[SystemZ] Rename mapping table fields Rename Function->DispKey and PairType->DispSize. I'd originally used "Function" because I thought it might be useful for other InstMappings. However, it turns out that having two very similar instructions with the same Function makes it pretty useless for anything other than the displacement size key. Other InstMappings will want the key to be defined for only one instruction in the pair. No behavioural change intended. llvm-svn: 185526

[SystemZ] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529

// Many register-based <INSN>R instructions have a memory-based <INSN>
[SystemZ] Refactor InstRR* instruction format patterns This changes the InstRR (and related) patterns to no longer automatically add an "r" at the end of the mnemonic. This makes the .td files more obviously understandable, and also allows using the patterns for those few instructions that do not follow the *r scheme. Also add some more sub-formats of the RRF format class, to match operand names and sequence from the PoP better. No functional change. llvm-svn: 286267

[SystemZ] Reuse CC results for integer comparisons with zero This also fixes a bug in the predication of LR to LOCR: I'd forgotten that with these in-place instruction builds, the implicit operands need to be added manually.

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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] Register compare-and-branch support This patch adds support for the CRJ and CGRJ instructions. Support for the immediate forms will be a separate patch. The architecture has a large number of comparison instructions. I think it's generally better to concentrate on using the "best" comparison instruction first and foremost, then only use something like CRJ if CR really was the natual choice of comparison instruction. The patch therefore opportunistically converts separate CR and BRC instructions into a single CRJ while emitting instructions in ISelLowering. llvm-svn: 182764

[SystemZ] Add remaining branch instructions This patch adds assembler support for the remaining branch instructions: the non-relative branch on count variants, and all variants of branch on index. The only one of those that can be readily exploited for code generation is BRCTH (branch on count using a high 32-bit register as count). Do use it, however, it is necessary to also introduce a hew CHIMux pseudo to allow comparisons of a 32-bit value agains a short immediate to go into a high register as well (implemented via CHI/CIH). This causes a bit of codegen changes overall, but those have proven to be neutral (or even beneficial) in performance measurements. llvm-svn: 288029

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Refactor branch and conditional instruction patterns Rework patterns for branches, call & return instructions, compare-and-branch, compare-and-trap, and conditional move instructions. In particular, simplify creation of patterns for the extended opcodes of instructions that take a CC mask. Also, use semantical instruction classes for all the instructions instead of open-coding them in SystemZInstrInfo.td. Adds a couple of the basic branch instructions (that are unused for codegen) for the assembler/disassembler. llvm-svn: 286263

[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] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Refactor branch and conditional instruction patterns Rework patterns for branches, call & return instructions, compare-and-branch, compare-and-trap, and conditional move instructions. In particular, simplify creation of patterns for the extended opcodes of instructions that take a CC mask. Also, use semantical instruction classes for all the instructions instead of open-coding them in SystemZInstrInfo.td. Adds a couple of the basic branch instructions (that are unused for codegen) for the assembler/disassembler. llvm-svn: 286263

[SystemZ] Fix encoding of MVCK and .insn ss LLVM currently treats the first operand of MVCK as if it were a regular base+index+displacement address. However, it is in fact a base+displacement combined with a length register field. While the two might look syntactically similar, there are two semantic differences: - %r0 is a valid length register, even though it cannot be used as an index register. - In an expression with just a single register like 0(%rX), the register is treated as base with normal addresses, while it is treated as the length register (with an empty base) for MVCK. Fixed by adding a new operand parser class BDRAddr and reworking the assembler parser to distinguish between address + length register operands and regular addresses. llvm-svn: 285574

[SystemZ] Fix encoding of MVCK and .insn ss LLVM currently treats the first operand of MVCK as if it were a regular base+index+displacement address. However, it is in fact a base+displacement combined with a length register field. While the two might look syntactically similar, there are two semantic differences: - %r0 is a valid length register, even though it cannot be used as an index register. - In an expression with just a single register like 0(%rX), the register is treated as base with normal addresses, while it is treated as the length register (with an empty base) for MVCK. Fixed by adding a new operand parser class BDRAddr and reworking the assembler parser to distinguish between address + length register operands and regular addresses. llvm-svn: 285574

[SystemZ] Support transactional execution on zEC12 The zEC12 provides the transactional-execution facility. This is exposed to users via a set of builtin routines on other compilers. This patch adds LLVM support to enable those builtins. In partciular, the patch: - adds the transactional-execution and processor-assist facilities - adds MC support for all instructions provided by those facilities - adds LLVM intrinsics for those instructions and hooks them up for CodeGen - adds CodeGen support to optimize CC return value checking Since this is first use of target-specific intrinsics on the platform, the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix to return "s390" instead of "systemz", since the naming convention for GCC intrinsics uses "s390" on the platform, and it neemed more straight- forward to use the same convention for LLVM IR intrinsics. An associated clang patch makes the intrinsics (and command line switches) available at the source-language level. For reference, the transactional-execution instructions are documented in the z/Architecture Principles of Operation for the zEC12: http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf The associated builtins are documented in the GCC manual: http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html Index: llvm-head/lib/Target/SystemZ/SystemZOperators.td =================================================================== --- llvm-head.orig/lib/Target/SystemZ/SystemZOperators.td +++ llvm-head/lib/Target/SystemZ/SystemZOperators.td @@ -79,6 +79,9 @@ def SDT_ZI32Intrinsic : SDTypeProf def SDT_ZPrefetch : SDTypeProfile<0, 2, [SDTCisVT<0, i32>, SDTCisPtrTy<1>]>;

[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

//===----------------------------------------------------------------------===//
// Variants of instructions with condition mask
//===----------------------------------------------------------------------===//
//
// For instructions using a condition mask (e.g. conditional branches,
// compare-and-branch instructions, or conditional move instructions),
// we generally need to create multiple instruction patterns:
//
// - One used for code generation, which encodes the condition mask as an
// MI operand, but writes out an extended mnemonic for better readability.
// - One pattern for the base form of the instruction with an explicit
// condition mask (encoded as a plain integer MI operand).
// - Specific patterns for each extended mnemonic, where the condition mask
// is implied by the pattern name and not otherwise encoded at all.
//
// We need the latter primarily for the assembler and disassembler, since the
// assembler parser is not able to decode part of an instruction mnemonic
// into an operand. Thus we provide separate patterns for each mnemonic.
//
// Note that in some cases there are two different mnemonics for the same
// condition mask. In this case we cannot have both instructions available
// to the disassembler at the same time since the encodings are not distinct.
// Therefore the alternate forms are marked isAsmParserOnly.
//
// We don't make one of the two names an alias of the other because
// we need the custom parsing routines to select the correct register class.
//
// This section provides helpers for generating the specific forms.

The only one of those that can be readily exploited for code generation is BRCTH (branch on count using a high 32-bit register as count). Do use it, however, it is necessary to also introduce a hew CHIMux pseudo to allow comparisons of a 32-bit value agains a short immediate to go into a high register as well (implemented via CHI/CIH).

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Refactor branch and conditional instruction patterns Rework patterns for branches, call & return instructions, compare-and-branch, compare-and-trap, and conditional move instructions. In particular, simplify creation of patterns for the extended opcodes of instructions that take a CC mask. Also, use semantical instruction classes for all the instructions instead of open-coding them in SystemZInstrInfo.td.

[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

The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529

[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.

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though.

[SystemZ] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529

[SystemZ] Improve use of conditional instructions This patch moves formation of LOC-type instructions from (late) IfConversion to the early if-conversion pass, and in some cases additionally creates them directly from select instructions during DAG instruction selection. To make early if-conversion work, the patch implements the canInsertSelect / insertSelect callbacks. It also implements the commuteInstructionImpl and FoldImmediate callbacks to enable generation of the full range of LOC instructions. Finally, the patch adds support for all instructions of the load-store-on-condition-2 facility, which allows using LOC instructions also for high registers. Due to the use of the GRX32 register class to enable high registers, we now also have to handle the cases where there are still no single hardware instructions (conditional move from a low register to a high register or vice versa). These are converted back to a branch sequence after register allocation. Since the expandRAPseudos callback is not allowed to create new basic blocks, this requires a simple new pass, modelled after the ARM/AArch64 ExpandPseudos pass. Overall, this patch causes significantly more LOC-type instructions to be used, and results in a measurable performance improvement. llvm-svn: 288028

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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.

[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] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

RegisterOperand cls, SDPatternOperator load, bits<5> bytes>
[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[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] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists.

The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Refactor branch and conditional instruction patterns Rework patterns for branches, call & return instructions, compare-and-branch, compare-and-trap, and conditional move instructions. In particular, simplify creation of patterns for the extended opcodes of instructions that take a CC mask. Also, use semantical instruction classes for all the instructions instead of open-coding them in SystemZInstrInfo.td. Adds a couple of the basic branch instructions (that are unused for codegen) for the assembler/disassembler. llvm-svn: 286263

[SystemZ] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands. The main complication is that addresses are compound operands, and as far as I know there is no mechanism to allow individual suboperands to be selected by name in "let Inst{...} = ..." assignments. Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order. (It was easier to do this at the same time as the rename, since otherwise the intermediate step was too confusing.) No functional change intended. llvm-svn: 181769

[SystemZ] Refactor InstRR* instruction format patterns This changes the InstRR (and related) patterns to no longer automatically add an "r" at the end of the mnemonic. This makes the .td files more obviously understandable, and also allows using the patterns for those few instructions that do not follow the *r scheme. Also add some more sub-formats of the RRF format class, to match operand names and sequence from the PoP better. No functional change. llvm-svn: 286267

[SystemZ] Fold more spills Add a mapping from register-based <INSN>R instructions to the corresponding memory-based <INSN>. Use it to cut down on the number of spill loads. Some instructions extend their operands from smaller fields, so this required a new TSFlags field to say how big the unextended operand is. This optimisation doesn't trigger for C(G)R and CL(G)R because in practice we always combine those instructions with a branch. Adding a test for every other case probably seems excessive, but it did catch a missed optimisation for DSGF (fixed in r185435). llvm-svn: 185529

[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 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] Match operands to fields by name rather than by order The SystemZ port currently relies on the order of the instruction operands matching the order of the instruction field lists. This isn't desirable for disassembly, where the two are matched only by name. E.g. the R1 and R2 fields of an RR instruction should have corresponding R1 and R2 operands.

Luckily it doesn't really matter though. The SystemZ instruction encoding groups all address fields together in a predictable order, so it's just as valid to see the entire compound address operand as a single field. That's the approach taken in this patch. Matching by name in turn means that the operands to COPY SIGN and CONVERT TO FIXED instructions can be given in natural order.

[SystemZ] Add remaining branch instructions This patch adds assembler support for the remaining branch instructions: the non-relative branch on count variants, and all variants of branch on index. The only one of those that can be readily exploited for code generation is BRCTH (branch on count using a high 32-bit register as count). Do use it, however, it is necessary to also introduce a hew CHIMux pseudo to allow comparisons of a 32-bit value agains a short immediate to go into a high register as well (implemented via CHI/CIH). This causes a bit of codegen changes overall, but those have proven to be neutral (or even beneficial) in performance measurements. llvm-svn: 288029

[SystemZ] Improve use of conditional instructions This patch moves formation of LOC-type instructions from (late) IfConversion to the early if-conversion pass, and in some cases additionally creates them directly from select instructions during DAG instruction selection. To make early if-conversion work, the patch implements the canInsertSelect / insertSelect callbacks. It also implements the commuteInstructionImpl and FoldImmediate callbacks to enable generation of the full range of LOC instructions. Finally, the patch adds support for all instructions of the load-store-on-condition-2 facility, which allows using LOC instructions also for high registers. Due to the use of the GRX32 register class to enable high registers, we now also have to handle the cases where there are still no single hardware instructions (conditional move from a low register to a high register or vice versa). These are converted back to a branch sequence after register allocation. Since the expandRAPseudos callback is not allowed to create new basic blocks, this requires a simple new pass, modelled after the ARM/AArch64 ExpandPseudos pass. Overall, this patch causes significantly more LOC-type instructions to be used, and results in a measurable performance improvement. llvm-svn: 288028

[SystemZ] Be more careful about inverting CC masks System z branches have a mask to select which of the 4 CC values should cause the branch to be taken. We can invert a branch by inverting the mask. However, not all instructions can produce all 4 CC values, so inverting the branch like this can lead to some oddities. For example, integer comparisons only produce a CC of 0 (equal), 1 (less) or 2 (greater). If an integer EQ is reversed to NE before instruction selection, the branch will test for 1 or 2. If instead the branch is reversed after instruction selection (by inverting the mask), it will test for 1, 2 or 3. Both are correct, but the second isn't really canonical. This patch therefore keeps track of which CC values are possible and uses this when inverting a mask. Although this is mostly cosmestic, it fixes undefined behavior for the CIJNLH in branch-08.ll. Another fix would have been to mask out bit 0 when generating the fused compare and branch, but the point of this patch is that we shouldn't need to do that in the first place. The patch also makes it easier to reuse CC results from other instructions. llvm-svn: 187495

However, not all instructions can produce all 4 CC values, so inverting the branch like this can lead to some oddities. For example, integer comparisons only produce a CC of 0 (equal), 1 (less) or 2 (greater). If an integer EQ is reversed to NE before instruction selection, the branch will test for 1 or 2. If instead the branch is reversed after instruction selection (by inverting the mask), it will test for 1, 2 or 3. Both are correct, but the second isn't really canonical. This patch therefore keeps track of which CC values are possible and uses this when inverting a mask. Although this is mostly cosmestic, it fixes undefined behavior for the CIJNLH in branch-08.ll. Another fix would have been to mask out bit 0 when generating the fused compare and branch, but the point of this patch is that we shouldn't need to do that in the first place. The patch also makes it easier to reuse CC results from other instructions. llvm-svn: 187495

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] Use upper words of GR64s for codegen This just adds the basics necessary for allocating the upper words to virtual registers (move, load and store). The move support is parameterised in a way that makes it easy to handle zero extensions, but the associated zero-extend patterns are added by a later patch. The easiest way of testing this seemed to be add a new "h" register constraint for high words.

[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] Use upper words of GR64s for codegen This just adds the basics necessary for allocating the upper words to virtual registers (move, load and store). The move support is parameterised in a way that makes it easy to handle zero extensions, but the associated zero-extend patterns are added by a later patch. The easiest way of testing this seemed to be add a new "h" register constraint for high words. I don't expect the constraint to be useful in real inline asms, but it should work, so I didn't try to hide it behind an option. llvm-svn: 191739
