[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

def VLR : UnaryVRRa<"vlr", 0xE756, null_frag, v128any, v128any>;
[SystemZ] Add support for IBM z14 processor (2/3) This adds support for the new 32-bit vector float instructions of z14. This includes: - Enabling the instructions for the assembler/disassembler. - CodeGen for the instructions, including new LLVM intrinsics. - Scheduler description support for the instructions. - Update to the vector cost function calculations. In general, CodeGen support for the new v4f32 instructions closely matches support for the existing v2f64 instructions. llvm-svn: 308195

def VLR32 : UnaryAliasVRR<null_frag, v32sb, v32sb>;
[SystemZ] Add CodeGen support for scalar f64 ops in vector registers The z13 vector facility includes some instructions that operate only on the high f64 in a v2f64, effectively extending the FP register set from 16 to 32 registers. It's still better to use the old instructions if the operands happen to fit though, since the older instructions have a shorter encoding. Based on a patch by Richard Sandiford. llvm-svn: 236524

// Load GR from VR element.
[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] set 'guessInstructionProperties = 0' and set flags as needed. This has proven a healthy exercise, as many cases of incorrect instruction flags were corrected in the process. As part of this, IntrWriteMem was added to several SystemZ instrinsics. Furthermore, a bug was exposed in TwoAddress with this change (as incorrect hasSideEffects flags were removed and instructions could now be sunk), and the test case for that bugfix (r319646) is included here as test/CodeGen/SystemZ/twoaddr-sink.ll.

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add CodeGen support for v4f32 The architecture doesn't really have any native v4f32 operations except v4f32->v2f64 and v2f64->v4f32 conversions, with only half of the v4f32 elements being used. Even so, using vector registers for <4 x float> and scalarising individual operations is much better than generating completely scalar code, since there's much less register pressure. It's also more efficient to do v4f32 comparisons by extending to 2 v2f64s, comparing those, then packing the result. This particularly helps with llvmpipe.

// Use VLREP to load subvectors. These patterns use "12pair" because
// LEY and LDY offer full 20-bit displacement fields. It's often better
// to use those instructions rather than force a 20-bit displacement
// into a GPR temporary.
[SystemZ] set 'guessInstructionProperties = 0' and set flags as needed. This has proven a healthy exercise, as many cases of incorrect instruction flags were corrected in the process. As part of this, IntrWriteMem was added to several SystemZ instrinsics. Furthermore, a bug was exposed in TwoAddress with this change (as incorrect hasSideEffects flags were removed and instructions could now be sunk), and the test case for that bugfix (r319646) is included here as test/CodeGen/SystemZ/twoaddr-sink.ll.

This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add CodeGen support for v4f32 The architecture doesn't really have any native v4f32 operations except v4f32->v2f64 and v2f64->v4f32 conversions, with only half of the v4f32 elements being used. Even so, using vector registers for <4 x float> and scalarising individual operations is much better than generating completely scalar code, since there's much less register pressure. It's also more efficient to do v4f32 comparisons by extending to 2 v2f64s, comparing those, then packing the result. This particularly helps with llvmpipe.

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add CodeGen support for scalar f64 ops in vector registers The z13 vector facility includes some instructions that operate only on the high f64 in a v2f64, effectively extending the FP register set from 16 to 32 registers. It's still better to use the old instructions if the operands happen to fit though, since the older instructions have a shorter encoding. Based on a patch by Richard Sandiford. llvm-svn: 236524

// Use VSTE to store subvectors. These patterns use "12pair" because
// STEY and STDY offer full 20-bit displacement fields. It's often better
// to use those instructions rather than force a 20-bit displacement
// into a GPR temporary.
[SystemZ] set 'guessInstructionProperties = 0' and set flags as needed. This has proven a healthy exercise, as many cases of incorrect instruction flags were corrected in the process. As part of this, IntrWriteMem was added to several SystemZ instrinsics. Furthermore, a bug was exposed in TwoAddress with this change (as incorrect hasSideEffects flags were removed and instructions could now be sunk), and the test case for that bugfix (r319646) is included here as test/CodeGen/SystemZ/twoaddr-sink.ll. One temporary test regression (one extra copy) which will hopefully go away in upcoming patches for similar cases: test/CodeGen/SystemZ/vec-trunc-to-i1.ll Review: Ulrich Weigand. https://reviews.llvm.org/D40437 llvm-svn: 319756

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms.

Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields.

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions.

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

The patch includes some simple tests for sub-128 vectors and also tests that we can recognize various pack sequences, some of which use sub-128 vectors as temporary results. One of these forms is based on the pack sequences generated by llvmpipe when no intrinsics are used. Signed unpacks are recognized as BUILD_VECTORs whose elements are individually sign-extended. Unsigned unpacks can have the equivalent form with zero extension, but they also occur as shuffles in which some elements are zero. Based on a patch by Richard Sandiford. llvm-svn: 236525

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add CodeGen support for v4f32 The architecture doesn't really have any native v4f32 operations except v4f32->v2f64 and v2f64->v4f32 conversions, with only half of the v4f32 elements being used. Even so, using vector registers for <4 x float> and scalarising individual operations is much better than generating completely scalar code, since there's much less register pressure. It's also more efficient to do v4f32 comparisons by extending to 2 v2f64s, comparing those, then packing the result. This particularly helps with llvmpipe.

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add vector intrinsics This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

def VMAL : TernaryVRRdGeneric<"vmal", 0xE7AA>;
[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level.

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add vector intrinsics This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527

This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI.

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level.

[SystemZ] Add support for IBM z14 processor (3/3) This adds support for the new 128-bit vector float instructions of z14. Note that these instructions actually only operate on the f128 type, since only each 128-bit vector register can hold only one 128-bit float value. However, this is still preferable to the legacy 128-bit float instructions, since those operate on pairs of floating-point registers (so we can hold at most 8 values in registers), while the new instructions use single vector registers (so we hold up to 32 value in registers). Adding support includes: - Enabling the instructions for the assembler/disassembler. - CodeGen for the instructions. This includes allocating the f128 type now to the VR128BitRegClass instead of FP128BitRegClass. - Scheduler description support for the instructions. Note that for a small number of operations, we have no new vector instructions (like integer <-> 128-bit float conversions), and so we use the legacy instruction and then reformat the operand (i.e. copy between a pair of floating-point registers and a vector register). llvm-svn: 308196

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

However, this is still preferable to the legacy 128-bit float instructions, since those operate on pairs of floating-point registers (so we can hold at most 8 values in registers), while the new instructions use single vector registers (so we hold up to 32 value in registers). Adding support includes: - Enabling the instructions for the assembler/disassembler. - CodeGen for the instructions. This includes allocating the f128 type now to the VR128BitRegClass instead of FP128BitRegClass. - Scheduler description support for the instructions. Note that for a small number of operations, we have no new vector instructions (like integer <-> 128-bit float conversions), and so we use the legacy instruction and then reformat the operand (i.e. copy between a pair of floating-point registers and a vector register). llvm-svn: 308196

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add CodeGen support for v4f32 The architecture doesn't really have any native v4f32 operations except v4f32->v2f64 and v2f64->v4f32 conversions, with only half of the v4f32 elements being used. Even so, using vector registers for <4 x float> and scalarising individual operations is much better than generating completely scalar code, since there's much less register pressure. It's also more efficient to do v4f32 comparisons by extending to 2 v2f64s, comparing those, then packing the result. This particularly helps with llvmpipe.

Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add support for IBM z14 processor (3/3) This adds support for the new 128-bit vector float instructions of z14.

However, this is still preferable to the legacy 128-bit float instructions, since those operate on pairs of floating-point registers (so we can hold at most 8 values in registers), while the new instructions use single vector registers (so we hold up to 32 value in registers). Adding support includes: - Enabling the instructions for the assembler/disassembler. - CodeGen for the instructions. This includes allocating the f128 type now to the VR128BitRegClass instead of FP128BitRegClass. - Scheduler description support for the instructions. Note that for a small number of operations, we have no new vector instructions (like integer <-> 128-bit float conversions), and so we use the legacy instruction and then reformat the operand (i.e. copy between a pair of floating-point registers and a vector register). llvm-svn: 308196

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction.

[SystemZ] Add support for IBM z14 processor (3/3) This adds support for the new 128-bit vector float instructions of z14. Note that these instructions actually only operate on the f128 type, since only each 128-bit vector register can hold only one 128-bit float value. However, this is still preferable to the legacy 128-bit float instructions, since those operate on pairs of floating-point registers (so we can hold at most 8 values in registers), while the new instructions use single vector registers (so we hold up to 32 value in registers). Adding support includes: - Enabling the instructions for the assembler/disassembler. - CodeGen for the instructions. This includes allocating the f128 type now to the VR128BitRegClass instead of FP128BitRegClass. - Scheduler description support for the instructions. Note that for a small number of operations, we have no new vector instructions (like integer <-> 128-bit float conversions), and so we use the legacy instruction and then reformat the operand (i.e. copy between a pair of floating-point registers and a vector register). llvm-svn: 308196

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

Note that these instructions actually only operate on the f128 type, since only each 128-bit vector register can hold only one 128-bit float value. However, this is still preferable to the legacy 128-bit float instructions, since those operate on pairs of floating-point registers (so we can hold at most 8 values in registers), while the new instructions use single vector registers (so we hold up to 32 value in registers).

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add vector intrinsics This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527

[SystemZ] Add CodeGen support for integer vector types This the first of a series of patches to add CodeGen support exploiting the instructions of the z13 vector facility. This patch adds support for the native integer vector types (v16i8, v8i16, v4i32, v2i64). When the vector facility is present, we default to the new vector ABI. This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

This is characterized by two major differences: - Vector types are passed/returned in vector registers (except for unnamed arguments of a variable-argument list function). - Vector types are at most 8-byte aligned. The reason for the choice of 8-byte vector alignment is that the hardware is able to efficiently load vectors at 8-byte alignment, and the ABI only guarantees 8-byte alignment of the stack pointer, so requiring any higher alignment for vectors would require dynamic stack re-alignment code. However, for compatibility with old code that may use vector types, when *not* using the vector facility, the old alignment rules (vector types are naturally aligned) remain in use. These alignment rules are not only implemented at the C language level (implemented in clang), but also at the LLVM IR level. This is done by selecting a different DataLayout string depending on whether the vector ABI is in effect or not. Based on a patch by Richard Sandiford. llvm-svn: 236521

[SystemZ] Add CodeGen support for v4f32 The architecture doesn't really have any native v4f32 operations except v4f32->v2f64 and v2f64->v4f32 conversions, with only half of the v4f32 elements being used. Even so, using vector registers for <4 x float> and scalarising individual operations is much better than generating completely scalar code, since there's much less register pressure. It's also more efficient to do v4f32 comparisons by extending to 2 v2f64s, comparing those, then packing the result. This particularly helps with llvmpipe.

[SystemZ] Add z13 vector facility and MC support This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520

[SystemZ] Add missing vector instructions for the assembler Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586

[SystemZ] Add vector intrinsics This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527
