It is possible for several constants which aren't individually absorbing to combine to the absorbing element. Thanks to nbjoerg on IRC for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158399 91177308-0d34-0410-b5e6-96231b3b80d8 2012-06-13 12:15:56 +00:00			`; RUN: opt -S -reassociate < %s \| FileCheck %s`

Update Transforms tests to use CHECK-LABEL for easier debugging. No functionality change. This update was done with the following bash script: find test/Transforms -name ".ll" \| \ while read NAME; do echo "$NAME" if ! grep -q "^; RUN: llc" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]@\([A-Za-z0-9_]\)(.$/\1/p" < $NAME \| \ while read FUNC; do sed -i '' "s/;\(.\)\([A-Za-z0-9_]\):\( \)@$FUNC\([( ]\)\$/;\1\2-LABEL:\3@$FUNC(/g" $TEMP done mv $TEMP $NAME fi done git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186268 91177308-0d34-0410-b5e6-96231b3b80d8 2013-07-14 01:42:54 +00:00			`; CHECK-LABEL: @foo(`
