llvm-mirror/test/CodeGen/AArch64/setcc-takes-i32.ll
Stephen Lin 3ae734a60c Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier 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.

; Most important point here is that the promotion of the i1 works
; correctly. Previously LLVM thought that i64 was the appropriate SetCC output,
; which meant it proceded in two steps and produced an i64 -> i64 any_ext which
; couldn't be selected and faulted.
; It was expecting the smallest legal promotion of i1 to be the preferred SetCC
; type, so we'll satisfy it (this actually arguably gives better code anyway,
; with flag-manipulation operations allowed to use W-registers).
