| * | [X86] Handle COPYs of physregs better (regalloc hints) | Simon Pilgrim | 2018-09-19 | 1 | -18/+18 |
| | | | | | | | | | | | | | | | 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.

| * | [CodeGen] Unify MBB reference format in both MIR and debug output | Francis Visoiu Mistrih | 2017-12-04 | 1 | -9/+9 |
| | | | | | | | | | | | | | | | | | As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'. The MIR printer prints the IR name of a MBB only for block definitions. * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)->getNumber\(\)/" << printMBBReference(*\1)/g' * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)\.getNumber\(\)/" << printMBBReference(\1)/g' * find . \( -name "*.txt" -o -name "*.s" -o -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#([0-9]+)/%bb.\1/g' * grep -nr 'BB#' and fix Differential Revision: https://reviews.llvm.org/D40422 llvm-svn: 319665 | ||||

| * | Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵ | Stephen Lin | 2013-07-13 | 1 | -8/+8 |
| | | | | | | | | | | | debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258 | ||||
| * | Add some x86 specific dagcombines for conditional increments. | Benjamin Kramer | 2010-12-21 | 1 | -0/+89 |
| (add Y, (sete X, 0)) -> cmp X, 1; adc 0, Y (add Y, (setne X, 0)) -> cmp X, 1; sbb -1, Y (sub (sete X, 0), Y) -> cmp X, 1; sbb 0, Y (sub (setne X, 0), Y) -> cmp X, 1; adc -1, Y for unsigned foo(unsigned a, unsigned b) { if (a == 0) b++; return b; } we now get: foo: cmpl $1, %edi movl %esi, %eax adcl $0, %eax ret instead of: foo: testl %edi, %edi sete %al movzbl %al, %eax addl %esi, %eax ret llvm-svn: 122364 | |||||
