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).
