VirtRegMap: Replace some identity copies with KILL instructions. An identity COPY like this: %AL = COPY %AL, %EAX<imp-def> has no semantic effect, but encodes liveness information: Further users of %EAX only depend on this instruction even though it does not define the full register. Replace the COPY with a KILL instruction in those cases to maintain this liveness information. (This reverts a small part of r238588 but this time adds a comment explaining why a KILL instruction is useful). llvm-svn: 274952

[x86] don't blindly transform SETB into SBB I noticed unnecessary 'sbb' instructions in D30472 and while looking at 'ptest' codegen recently. This happens because we were transforming any 'setb' - even when we only wanted a single-bit result. This patch moves those transforms under visitAdd/visitSub, so we we're only creating sbb/adc when it is a win. I don't know why we need a SETCC_CARRY node type, but I'm not proposing to change that existing behavior in this patch. Also, I'm skeptical that sbb/adc are a win for all micro-arches, so I added comments to the test files where this transform still fires. The test changes here are all cases where we no longer produce sbb/adc. Avoiding partial register stalls (generating an xor to clear a register) is not handled in some cases, but that's a separate issue.

[X86][AVX512] Make i1 illegal in the CodeGen This patch defines the i1 type as illegal in the X86 backend for AVX512. For DAG operations on <N x i1> types (build vector, extract vector element, ...) i8 is used, and should be truncated/extended. This should produce better scalar code for i1 types since GPRs will be used instead of mask registers. Differential Revision: https://reviews.llvm.org/D32273 llvm-svn: 303421

[AVX-512] Fix accidental uses of AH/BH/CH/DH after copies to/from mask registers We've had several bugs(PR32256, PR32241) recently that resulted from usages of AH/BH/CH/DH either before or after a copy to/from a mask register. This ultimately occurs because we create COPY_TO_REGCLASS with VK1 and GR8. Then in CopyToFromAsymmetricReg in X86InstrInfo we find a 32-bit super register for the GR8 to emit the KMOV with. But as these tests are demonstrating, its possible for the GR8 register to be a high register and we end up doing an accidental extra or insert from bits 15:8. I think the best way forward is to stop making copies directly between mask registers and GR8/GR16. Instead I think we should restrict to only copies between mask registers and GR32/GR64 and use EXTRACT_SUBREG/INSERT_SUBREG to handle the conversion from GR32 to GR16/8 or vice versa. Unfortunately, this complicates fastisel a bit more now to create the subreg extracts where we used to create GR8 copies. We can probably make a helper function to bring down the repitition. This does result in KMOVD being used for copies when BWI is available because we don't know the original mask register size. This caused a lot of deltas on tests because we have to split the checks for KMOVD vs KMOVW based on BWI. Differential Revision: https://reviews.llvm.org/D30968 llvm-svn: 298928

This change effectively extracts the old value and the new value, xors them together and then xors that single bit with the correct location in the original vector. This will cancel out the old value in the first xor leaving the new value in the position. The way I've implemented this uses 3 shifts and two xors and uses an additional register.

It then calculates the cost of converting the closure to another domain. If found profitable, the instructions are converted to instructions in the other domain and the register classes are changed accordingly. This commit adds the pass infrastructure and a simple conversion from the GPR domain to the Mask domain.

[X86] Handle alls version of vXi1 insert_vector_elt with a constant index without falling back to shuffles. We previously only supported inserting to the LSB or MSB where it was easy to zero to perform an OR to insert. This change effectively extracts the old value and the new value, xors them together and then xors that single bit with the correct location in the original vector. This will cancel out the old value in the first xor leaving the new value in the position. The way I've implemented this uses 3 shifts and two xors and uses an additional register. We can avoid the additional register at the cost of another shift. llvm-svn: 320120

[AVX-512] Fix accidental uses of AH/BH/CH/DH after copies to/from mask registers We've had several bugs(PR32256, PR32241) recently that resulted from usages of AH/BH/CH/DH either before or after a copy to/from a mask register. This ultimately occurs because we create COPY_TO_REGCLASS with VK1 and GR8. Then in CopyToFromAsymmetricReg in X86InstrInfo we find a 32-bit super register for the GR8 to emit the KMOV with. But as these tests are demonstrating, its possible for the GR8 register to be a high register and we end up doing an accidental extra or insert from bits 15:8. I think the best way forward is to stop making copies directly between mask registers and GR8/GR16. Instead I think we should restrict to only copies between mask registers and GR32/GR64 and use EXTRACT_SUBREG/INSERT_SUBREG to handle the conversion from GR32 to GR16/8 or vice versa. Unfortunately, this complicates fastisel a bit more now to create the subreg extracts where we used to create GR8 copies. We can probably make a helper function to bring down the repitition. This does result in KMOVD being used for copies when BWI is available because we don't know the original mask register size. This caused a lot of deltas on tests because we have to split the checks for KMOVD vs KMOVW based on BWI. Differential Revision: https://reviews.llvm.org/D30968 llvm-svn: 298928

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[x86] don't blindly transform SETB into SBB I noticed unnecessary 'sbb' instructions in D30472 and while looking at 'ptest' codegen recently. This happens because we were transforming any 'setb' - even when we only wanted a single-bit result. This patch moves those transforms under visitAdd/visitSub, so we we're only creating sbb/adc when it is a win. I don't know why we need a SETCC_CARRY node type, but I'm not proposing to change that existing behavior in this patch. Also, I'm skeptical that sbb/adc are a win for all micro-arches, so I added comments to the test files where this transform still fires. The test changes here are all cases where we no longer produce sbb/adc. Avoiding partial register stalls (generating an xor to clear a register) is not handled in some cases, but that's a separate issue.

[X86] Handle alls version of vXi1 insert_vector_elt with a constant index without falling back to shuffles. We previously only supported inserting to the LSB or MSB where it was easy to zero to perform an OR to insert. This change effectively extracts the old value and the new value, xors them together and then xors that single bit with the correct location in the original vector. This will cancel out the old value in the first xor leaving the new value in the position. The way I've implemented this uses 3 shifts and two xors and uses an additional register. We can avoid the additional register at the cost of another shift. llvm-svn: 320120

[X86] Make v2i1 and v4i1 legal types without VLX Summary: There are few oddities that occur due to v1i1, v8i1, v16i1 being legal without v2i1 and v4i1 being legal when we don't have VLX. Particularly during legalization of v2i32/v4i32/v2i64/v4i64 masked gather/scatter/load/store. We end up promoting the mask argument to these during type legalization and then have to widen the promoted type to v8iX/v16iX and truncate it to get the element size back down to v8i1/v16i1 to use a 512-bit operation. Since need to fill the upper bits of the mask we have to fill with 0s at the promoted type. It would be better if we could just have the v2i1/v4i1 types as legal so they don't undergo any promotion. Then we can just widen with 0s directly in a k register. There are no real v4i1/v2i1 instructions anyway. Everything is done on a larger register anyway. This also fixes an issue that we couldn't implement a masked vextractf32x4 from zmm to xmm properly. We now have to support widening more compares to 512-bit to get a mask result out so new tablegen patterns got added. I had to hack the legalizer for widening the operand of a setcc a bit so it didn't try create a setcc returning v4i32, extract from it, then try to promote it using a sign extend to v2i1. Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

[x86] don't blindly transform SETB into SBB I noticed unnecessary 'sbb' instructions in D30472 and while looking at 'ptest' codegen recently. This happens because we were transforming any 'setb' - even when we only wanted a single-bit result. This patch moves those transforms under visitAdd/visitSub, so we we're only creating sbb/adc when it is a win. I don't know why we need a SETCC_CARRY node type, but I'm not proposing to change that existing behavior in this patch. Also, I'm skeptical that sbb/adc are a win for all micro-arches, so I added comments to the test files where this transform still fires. The test changes here are all cases where we no longer produce sbb/adc. Avoiding partial register stalls (generating an xor to clear a register) is not handled in some cases, but that's a separate issue.

[X86] Handle alls version of vXi1 insert_vector_elt with a constant index without falling back to shuffles. We previously only supported inserting to the LSB or MSB where it was easy to zero to perform an OR to insert. This change effectively extracts the old value and the new value, xors them together and then xors that single bit with the correct location in the original vector. This will cancel out the old value in the first xor leaving the new value in the position. The way I've implemented this uses 3 shifts and two xors and uses an additional register. We can avoid the additional register at the cost of another shift. llvm-svn: 320120

[AVX-512] Fix accidental uses of AH/BH/CH/DH after copies to/from mask registers We've had several bugs(PR32256, PR32241) recently that resulted from usages of AH/BH/CH/DH either before or after a copy to/from a mask register. This ultimately occurs because we create COPY_TO_REGCLASS with VK1 and GR8. Then in CopyToFromAsymmetricReg in X86InstrInfo we find a 32-bit super register for the GR8 to emit the KMOV with. But as these tests are demonstrating, its possible for the GR8 register to be a high register and we end up doing an accidental extra or insert from bits 15:8. I think the best way forward is to stop making copies directly between mask registers and GR8/GR16. Instead I think we should restrict to only copies between mask registers and GR32/GR64 and use EXTRACT_SUBREG/INSERT_SUBREG to handle the conversion from GR32 to GR16/8 or vice versa. Unfortunately, this complicates fastisel a bit more now to create the subreg extracts where we used to create GR8 copies. We can probably make a helper function to bring down the repitition. This does result in KMOVD being used for copies when BWI is available because we don't know the original mask register size. This caused a lot of deltas on tests because we have to split the checks for KMOVD vs KMOVW based on BWI. Differential Revision: https://reviews.llvm.org/D30968 llvm-svn: 298928

[X86] Make v2i1 and v4i1 legal types without VLX Summary: There are few oddities that occur due to v1i1, v8i1, v16i1 being legal without v2i1 and v4i1 being legal when we don't have VLX. Particularly during legalization of v2i32/v4i32/v2i64/v4i64 masked gather/scatter/load/store. We end up promoting the mask argument to these during type legalization and then have to widen the promoted type to v8iX/v16iX and truncate it to get the element size back down to v8i1/v16i1 to use a 512-bit operation. Since need to fill the upper bits of the mask we have to fill with 0s at the promoted type. It would be better if we could just have the v2i1/v4i1 types as legal so they don't undergo any promotion. Then we can just widen with 0s directly in a k register. There are no real v4i1/v2i1 instructions anyway. Everything is done on a larger register anyway. This also fixes an issue that we couldn't implement a masked vextractf32x4 from zmm to xmm properly. We now have to support widening more compares to 512-bit to get a mask result out so new tablegen patterns got added. I had to hack the legalizer for widening the operand of a setcc a bit so it didn't try create a setcc returning v4i32, extract from it, then try to promote it using a sign extend to v2i1. Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

[X86] Make v2i1 and v4i1 legal types without VLX Summary: There are few oddities that occur due to v1i1, v8i1, v16i1 being legal without v2i1 and v4i1 being legal when we don't have VLX. Particularly during legalization of v2i32/v4i32/v2i64/v4i64 masked gather/scatter/load/store. We end up promoting the mask argument to these during type legalization and then have to widen the promoted type to v8iX/v16iX and truncate it to get the element size back down to v8i1/v16i1 to use a 512-bit operation. Since need to fill the upper bits of the mask we have to fill with 0s at the promoted type. It would be better if we could just have the v2i1/v4i1 types as legal so they don't undergo any promotion. Then we can just widen with 0s directly in a k register. There are no real v4i1/v2i1 instructions anyway. Everything is done on a larger register anyway. This also fixes an issue that we couldn't implement a masked vextractf32x4 from zmm to xmm properly. We now have to support widening more compares to 512-bit to get a mask result out so new tablegen patterns got added. I had to hack the legalizer for widening the operand of a setcc a bit so it didn't try create a setcc returning v4i32, extract from it, then try to promote it using a sign extend to v2i1. Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register.

[X86] Use min/max for vector ult/ugt compares if avoids a sign flip. Summary: Currently we only use min/max to help with ule/uge compares because it removes an invert of the result that would otherwise be needed. But we can also use it for ult/ugt compares if it will prevent the need for a sign bit flip needed to use pcmpgt at the cost of requiring an invert after the compare. I also refactored the code so that the max/min code is self contained and does its own return instead of setting up a flag to manipulate the rest of the function's behavior. Most of the test cases look ok with this. I did notice that we added instructions when one of the operands being sign flipped is a constant vector that we were able to constant fold the flip into. I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register. We could try to detect this and switch from min to max and change the compare operands to use the operand that gets reused in the compare.

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

This allows us to use the aligned opcode when we can which makes our test output more consistent between different modes. It also reduces the number of isel patterns we need.

[AVX-512] Don't use unmasked VMOVDQU8/16 for 8-bit or 16-bit element stores even when BWI instructions are supported. Always use VMOVDQA32/VMOVDQU32. We were already using the 32 bit element opcode if BWI isn't enabled, but there's no reason to change opcode if we have BWI. We will still use the 8/16 opcodes for masked stores though. This allows us to use the aligned opcode when we can which makes our test output more consistent between different modes. It also reduces the number of isel patterns we need. This is a slight inconsistency with loads which default to 64 bit element opcodes. I'll probably rectify that in a future patch.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370

[AVX-512] Don't use unmasked VMOVDQU8/16 for 8-bit or 16-bit element stores even when BWI instructions are supported. Always use VMOVDQA32/VMOVDQU32. We were already using the 32 bit element opcode if BWI isn't enabled, but there's no reason to change opcode if we have BWI. We will still use the 8/16 opcodes for masked stores though. This allows us to use the aligned opcode when we can which makes our test output more consistent between different modes. It also reduces the number of isel patterns we need. This is a slight inconsistency with loads which default to 64 bit element opcodes. I'll probably rectify that in a future patch.

[X86] Make v2i1 and v4i1 legal types without VLX Summary: There are few oddities that occur due to v1i1, v8i1, v16i1 being legal without v2i1 and v4i1 being legal when we don't have VLX. Particularly during legalization of v2i32/v4i32/v2i64/v4i64 masked gather/scatter/load/store. We end up promoting the mask argument to these during type legalization and then have to widen the promoted type to v8iX/v16iX and truncate it to get the element size back down to v8i1/v16i1 to use a 512-bit operation. Since need to fill the upper bits of the mask we have to fill with 0s at the promoted type. It would be better if we could just have the v2i1/v4i1 types as legal so they don't undergo any promotion. Then we can just widen with 0s directly in a k register. There are no real v4i1/v2i1 instructions anyway. Everything is done on a larger register anyway. This also fixes an issue that we couldn't implement a masked vextractf32x4 from zmm to xmm properly. We now have to support widening more compares to 512-bit to get a mask result out so new tablegen patterns got added. I had to hack the legalizer for widening the operand of a setcc a bit so it didn't try create a setcc returning v4i32, extract from it, then try to promote it using a sign extend to v2i1. Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

We now have to support widening more compares to 512-bit to get a mask result out so new tablegen patterns got added. I had to hack the legalizer for widening the operand of a setcc a bit so it didn't try create a setcc returning v4i32, extract from it, then try to promote it using a sign extend to v2i1. Now we create the setcc with v4i1 if the original setcc's result type is v2i1. Then extract that and don't sign extend it at all. There's definitely room for improvement with some follow up patches.

[X86] Make v2i1 and v4i1 legal types without VLX Summary: There are few oddities that occur due to v1i1, v8i1, v16i1 being legal without v2i1 and v4i1 being legal when we don't have VLX. Particularly during legalization of v2i32/v4i32/v2i64/v4i64 masked gather/scatter/load/store. We end up promoting the mask argument to these during type legalization and then have to widen the promoted type to v8iX/v16iX and truncate it to get the element size back down to v8i1/v16i1 to use a 512-bit operation. Since need to fill the upper bits of the mask we have to fill with 0s at the promoted type. It would be better if we could just have the v2i1/v4i1 types as legal so they don't undergo any promotion. Then we can just widen with 0s directly in a k register. There are no real v4i1/v2i1 instructions anyway. Everything is done on a larger register anyway.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370

[X86] Use min/max for vector ult/ugt compares if avoids a sign flip. Summary: Currently we only use min/max to help with ule/uge compares because it removes an invert of the result that would otherwise be needed. But we can also use it for ult/ugt compares if it will prevent the need for a sign bit flip needed to use pcmpgt at the cost of requiring an invert after the compare. I also refactored the code so that the max/min code is self contained and does its own return instead of setting up a flag to manipulate the rest of the function's behavior. Most of the test cases look ok with this. I did notice that we added instructions when one of the operands being sign flipped is a constant vector that we were able to constant fold the flip into. I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register. We could try to detect this and switch from min to max and change the compare operands to use the operand that gets reused in the compare.

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370

[X86] Use min/max for vector ult/ugt compares if avoids a sign flip. Summary: Currently we only use min/max to help with ule/uge compares because it removes an invert of the result that would otherwise be needed. But we can also use it for ult/ugt compares if it will prevent the need for a sign bit flip needed to use pcmpgt at the cost of requiring an invert after the compare. I also refactored the code so that the max/min code is self contained and does its own return instead of setting up a flag to manipulate the rest of the function's behavior. Most of the test cases look ok with this. I did notice that we added instructions when one of the operands being sign flipped is a constant vector that we were able to constant fold the flip into. I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register. We could try to detect this and switch from min to max and change the compare operands to use the operand that gets reused in the compare.

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here.

Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370

[DAGCombiner] Set the right SDLoc on a newly-created sextload (6/N) This teaches tryToFoldExtOfLoad to set the right location on a newly-created extload. With that in place, the logic for performing a certain ([s|z]ext (load ...)) combine becomes identical for sexts and zexts, and we can get rid of one copy of the logic. The test case churn is due to dependencies on IROrders inherited from the wrong SDLoc. Part of: llvm.org/PR37262 Differential Revision: https://reviews.llvm.org/D46158 llvm-svn: 332118

We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type.

Summary: Currently we only use min/max to help with ule/uge compares because it removes an invert of the result that would otherwise be needed. But we can also use it for ult/ugt compares if it will prevent the need for a sign bit flip needed to use pcmpgt at the cost of requiring an invert after the compare. I also refactored the code so that the max/min code is self contained and does its own return instead of setting up a flag to manipulate the rest of the function's behavior. Most of the test cases look ok with this. I did notice that we added instructions when one of the operands being sign flipped is a constant vector that we were able to constant fold the flip into. I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register. We could try to detect this and switch from min to max and change the compare operands to use the operand that gets reused in the compare.

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[DAGCombiner] Set the right SDLoc on a newly-created sextload (6/N) This teaches tryToFoldExtOfLoad to set the right location on a newly-created extload. With that in place, the logic for performing a certain ([s|z]ext (load ...)) combine becomes identical for sexts and zexts, and we can get rid of one copy of the logic. The test case churn is due to dependencies on IROrders inherited from the wrong SDLoc. Part of: llvm.org/PR37262 Differential Revision: https://reviews.llvm.org/D46158 llvm-svn: 332118

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370

[X86] Legalize v32i1 without BWI via splitting to v16i1 rather than the default of promoting to v32i8. Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[X86] Use min/max for vector ult/ugt compares if avoids a sign flip. Summary: Currently we only use min/max to help with ule/uge compares because it removes an invert of the result that would otherwise be needed. But we can also use it for ult/ugt compares if it will prevent the need for a sign bit flip needed to use pcmpgt at the cost of requiring an invert after the compare. I also refactored the code so that the max/min code is self contained and does its own return instead of setting up a flag to manipulate the rest of the function's behavior. Most of the test cases look ok with this. I did notice that we added instructions when one of the operands being sign flipped is a constant vector that we were able to constant fold the flip into. I also noticed that sometimes the SSE min/max clobbers a register that is needed after the compare. This resulted in an extra move being inserted before the min/max to preserve the register. We could try to detect this and switch from min to max and change the compare operands to use the operand that gets reused in the compare.

Summary: For the most part its better to keep v32i1 as a mask type of a narrower width than trying to promote it to a ymm register. I had to add some overrides to the methods that get the types for the calling convention so that we still use v32i8 for argument/return purposes. There are still some regressions in here. I definitely saw some around shuffles. I think we probably should move vXi1 shuffle from lowering to a DAG combine where I think the extend and truncate we have to emit would be better combined. I think we also need a DAG combine to remove trunc from (extract_vector_elt (trunc)) Overall this removes something like 13000 CHECK lines from lit tests.

[SelectionDAG][X86] Fix insert_vector_elt lowering for v32i1/v64i1 with non-constant index Summary: Currently we don't handle v32i1/v64i1 insert_vector_elt correctly as we fail to look at the number of elements closely and assume it can only be v16i1 or v8i1. We also can't type legalize v64i1 insert_vector_elt correctly on KNL due to the type not being byte addressable as required by the legalizing through memory accesses path requires. For the first issue, the patch now tries to pick a 512-bit register with the correct number of elements and promotes to that. For the second issue, we now extend the vector to a byte addressable type, do the stores to memory, load the two halves, and then truncate the halves back to the original type. Technically since we changed the type, we may not need two loads, but actually checking that is more work and for the v64i1 case we do need them.

[SelectionDAG] Reverse the order of operands in the ISD::ADD created by TargetLowering::getVectorElementPointer so that the FrameIndex is on the left. This seems to improve X86's ability to match this into an address computation. Otherwise the other operand gets assigned to the base register and the stack pointer + frame index ends up in the index register. But index registers can't encode ESP/RSP so we end up having to move it into another register to meet the constraint. I could try to improve the address matcher in X86, but swapping the producer seemed easier. Several other places already have the operands in this order so this is at least consistent. llvm-svn: 321370
