[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[DAGCombiner] eliminate shuffle of insert element I noticed this pattern in D38316 / D38388. We failed to combine a shuffle that is either repeating a scalar insertion at the same position in a vector or translated to a different element index. Like the earlier patch, this could be an instcombine too, but since we opted to make this a DAG transform earlier, I've made this one a DAG patch too. We do not need any legality checking because the new insert is identical to the existing insert except that it may have a different constant insertion operand. The constant insertion test in test/CodeGen/X86/vector-shuffle-combining.ll was the motivation for D38756. Differential Revision: https://reviews.llvm.org/D40209 llvm-svn: 320050

[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[DAGCombiner] eliminate shuffle of insert element I noticed this pattern in D38316 / D38388. We failed to combine a shuffle that is either repeating a scalar insertion at the same position in a vector or translated to a different element index. Like the earlier patch, this could be an instcombine too, but since we opted to make this a DAG transform earlier, I've made this one a DAG patch too. We do not need any legality checking because the new insert is identical to the existing insert except that it may have a different constant insertion operand.

[X86] Handle COPYs of physregs better (regalloc hints) Enable enableMultipleCopyHints() on X86. Original Patch by @jonpa: While enabling the mischeduler for SystemZ, it was discovered that for some reason a test needed one extra seemingly needless COPY (test/CodeGen/SystemZ/call-03.ll). The handling for that is resulted in this patch, which improves the register coalescing by providing not just one copy hint, but a sorted list of copy hints. On SystemZ, this gives ~12500 less register moves on SPEC, as well as marginally less spilling. Instead of improving just the SystemZ backend, the improvement has been implemented in common-code (calculateSpillWeightAndHint(). This gives a lot of test failures, but since this should be a general improvement I hope that the involved targets will help and review the test updates.

[DAGCombiner] eliminate shuffle of insert element I noticed this pattern in D38316 / D38388. We failed to combine a shuffle that is either repeating a scalar insertion at the same position in a vector or translated to a different element index. Like the earlier patch, this could be an instcombine too, but since we opted to make this a DAG transform earlier, I've made this one a DAG patch too. We do not need any legality checking because the new insert is identical to the existing insert except that it may have a different constant insertion operand. The constant insertion test in test/CodeGen/X86/vector-shuffle-combining.ll was the motivation for D38756. Differential Revision: https://reviews.llvm.org/D40209 llvm-svn: 320050
