* Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier ↵Stephen Lin2013-07-13
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186258 91177308-0d34-0410-b5e6-96231b3b80d8
* X86: Add a bunch of peeps for add and sub of SETB.Benjamin Kramer2011-05-08
"b + ((a < b) ? 1 : 0)" compiles into cmpl %esi, %edi adcl $0, %esi instead of cmpl %esi, %edi sbbl %eax, %eax andl $1, %eax addl %esi, %eax This saves a register, a false dependency on %eax (Intel's CPUs still don't ignore it) and it's shorter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131070 91177308-0d34-0410-b5e6-96231b3b80d8
