[SDAG] Introduce a new BITREVERSE node along with a corresponding LLVM intrinsic Several backends have instructions to reverse the order of bits in an integer. Conceptually matching such patterns is similar to @llvm.bswap, and it was mentioned in http://reviews.llvm.org/D14234 that it would be best if these patterns were matched in InstCombine instead of reimplemented in every different target. This patch introduces an intrinsic @llvm.bitreverse.i* that operates similarly to @llvm.bswap. For plumbing purposes there is also a new ISD node ISD::BITREVERSE, with simple expansion and promotion support. The intention is that InstCombine's BSWAP detection logic will be extended to support BITREVERSE too, and @llvm.bitreverse intrinsics emitted (if the backend supports lowering it efficiently). llvm-svn: 252878

; These tests just check that the plumbing is in place for @llvm.bitreverse. The
; actual output is massive at the moment as llvm.bitreverse is not yet legal.

[X86FixupBWInsts] More precise register liveness if no <imp-use> on MOVs. Summary: Subregister liveness tracking is not implemented for X86 backend, so sometimes the whole super register is said to be live, when only a subregister is really live. That might happen if the def and the use are located in different MBBs, see added fixup-bw-isnt.mir test. However, using knowledge of the specific instructions handled by the bw-fixup-pass we can get more precise liveness information which this change does.

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

[X86FixupBWInsts] More precise register liveness if no <imp-use> on MOVs. Summary: Subregister liveness tracking is not implemented for X86 backend, so sometimes the whole super register is said to be live, when only a subregister is really live. That might happen if the def and the use are located in different MBBs, see added fixup-bw-isnt.mir test. However, using knowledge of the specific instructions handled by the bw-fixup-pass we can get more precise liveness information which this change does.

[SDAG] Introduce a new BITREVERSE node along with a corresponding LLVM intrinsic Several backends have instructions to reverse the order of bits in an integer. Conceptually matching such patterns is similar to @llvm.bswap, and it was mentioned in http://reviews.llvm.org/D14234 that it would be best if these patterns were matched in InstCombine instead of reimplemented in every different target. This patch introduces an intrinsic @llvm.bitreverse.i* that operates similarly to @llvm.bswap. For plumbing purposes there is also a new ISD node ISD::BITREVERSE, with simple expansion and promotion support. The intention is that InstCombine's BSWAP detection logic will be extended to support BITREVERSE too, and @llvm.bitreverse intrinsics emitted (if the backend supports lowering it efficiently). llvm-svn: 252878

Conceptually matching such patterns is similar to @llvm.bswap, and it was mentioned in http://reviews.llvm.org/D14234 that it would be best if these patterns were matched in InstCombine instead of reimplemented in every different target. This patch introduces an intrinsic @llvm.bitreverse.i* that operates similarly to @llvm.bswap. For plumbing purposes there is also a new ISD node ISD::BITREVERSE, with simple expansion and promotion support. The intention is that InstCombine's BSWAP detection logic will be extended to support BITREVERSE too, and @llvm.bitreverse intrinsics emitted (if the backend supports lowering it efficiently). llvm-svn: 252878
