Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name ".ll" \| \ while read NAME; do echo "$NAME" if ! grep -q "^; RUN: llc.debug" $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 sed -i '' "s/;\(.\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done llvm-svn: 186280 2013-07-14 08:24:09 +02:00			`; CHECK-LABEL: foo:`
