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] Split bmi.ll into a bmi test and a bmi2 test. This moves all the bmi2 specific intrinsics to a separate test file and adds a bmi1 only command line to the existing bmi test. This will allow us to see the missed opportunity to use bextr to handle 64-bit 'and' with a large mask. This will be improved in an upcoming patch. llvm-svn: 309700

[CodeGen] Use MachineOperand::print in the MIRPrinter for MO_Register. Work towards the unification of MIR and debug output by refactoring the interfaces. For MachineOperand::print, keep a simple version that can be easily called from `dump()`, and a more complex one which will be called from both the MIRPrinter and MachineInstr::print.

[X86] Move matching of (and (srl/sra, C), (1<<C) - 1) to BEXTR/BEXTRI instruction to custom isel Recognizing this pattern during DAG combine hides information about the 'and' and the shift from other combines. I think it should be recognized at isel so its as late as possible. But it can't be done with table based isel because you need to be able to look at both immediates. This patch moves it to custom isel in X86ISelDAGToDAG.cpp. This does break a couple tests in tbm_patterns because we are now emitting an and_flag node or (cmp and, 0) that we dont' recognize yet. We already had this problem for several other TBM patterns so I think this fine and we can address of them together. I've also fixed a bug where the combine to BEXTR was preventing us from using a trick of zero extending AH to handle extracts of bits 15:8. We might still want to use BEXTR if it enables load folding. But honestly I hope we narrowed the load instead before got to isel. I think we should probably also support matching BEXTR from (srl/srl (and mask << C), C). But that should be a different patch. Differential Revision: https://reviews.llvm.org/D37592 llvm-svn: 313054

I've also fixed a bug where the combine to BEXTR was preventing us from using a trick of zero extending AH to handle extracts of bits 15:8. We might still want to use BEXTR if it enables load folding. But honestly I hope we narrowed the load instead before got to isel. I think we should probably also support matching BEXTR from (srl/srl (and mask << C), C). But that should be a different patch. Differential Revision: https://reviews.llvm.org/D37592 llvm-svn: 313054

[X86] Add more patterns for BZHI isel This patch adds more patterns that a reasonable person might write that can be compiled to BZHI. This adds support for (~0U >> (32 - b)) & a; and a << (32 - b) >> (32 - b); This was inspired by the code in APInt::clearUnusedBits. This can pass an index of 32 to the bzhi instruction which a quick test of Haswell hardware shows will not mask any bits. Though the description text in the Intel manual says the "index is saturated to OperandSize-1". The pseudocode in the same manual indicates no bits will be zeroed for this case. I think this is still missing cases where the subtract portion is an 8-bit operation. Differential Revision: https://reviews.llvm.org/D32616 llvm-svn: 302549

[X86] Add more patterns for BZHI isel This patch adds more patterns that a reasonable person might write that can be compiled to BZHI. This adds support for (~0U >> (32 - b)) & a; and a << (32 - b) >> (32 - b); This was inspired by the code in APInt::clearUnusedBits. This can pass an index of 32 to the bzhi instruction which a quick test of Haswell hardware shows will not mask any bits. Though the description text in the Intel manual says the "index is saturated to OperandSize-1". The pseudocode in the same manual indicates no bits will be zeroed for this case. I think this is still missing cases where the subtract portion is an 8-bit operation. Differential Revision: https://reviews.llvm.org/D32616 llvm-svn: 302549

[X86] Add more patterns for BZHI isel This patch adds more patterns that a reasonable person might write that can be compiled to BZHI. This adds support for (~0U >> (32 - b)) & a; and a << (32 - b) >> (32 - b); This was inspired by the code in APInt::clearUnusedBits. This can pass an index of 32 to the bzhi instruction which a quick test of Haswell hardware shows will not mask any bits. Though the description text in the Intel manual says the "index is saturated to OperandSize-1". The pseudocode in the same manual indicates no bits will be zeroed for this case. I think this is still missing cases where the subtract portion is an 8-bit operation. Differential Revision: https://reviews.llvm.org/D32616 llvm-svn: 302549

[X86] Add more patterns for BZHI isel This patch adds more patterns that a reasonable person might write that can be compiled to BZHI. This adds support for (~0U >> (32 - b)) & a; and a << (32 - b) >> (32 - b); This was inspired by the code in APInt::clearUnusedBits. This can pass an index of 32 to the bzhi instruction which a quick test of Haswell hardware shows will not mask any bits. Though the description text in the Intel manual says the "index is saturated to OperandSize-1". The pseudocode in the same manual indicates no bits will be zeroed for this case. I think this is still missing cases where the subtract portion is an 8-bit operation. Differential Revision: https://reviews.llvm.org/D32616 llvm-svn: 302549

[X86] Use BEXTR/BEXTRI for 64-bit 'and' with a large mask Summary: The 64-bit 'and' with immediate instruction only supports a 32-bit immediate. So for larger constants we have to load the constant into a register first. If the immediate happens to be a mask we can use the BEXTRI instruction to perform the masking. We already do something similar using the BZHI instruction from the BMI2 instruction set.
