Fix a bug in the type-legalization of vector integers. When we bitcast one vector type to another, we must not bitcast the result if one type is widened while the other is promoted. llvm-svn: 148383 2012-01-18 09:33:18 +01:00			`; RUN: llc < %s -march=x86-64 -mcpu=corei7 -mtriple=x86_64-pc-win32 \| FileCheck %s`

Update to more CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change. All changes were made by the following bash script: find test/CodeGen -name ".ll" \| \ while read NAME; do echo "$NAME" grep -q "^; RUN: llc.debug" $NAME && continue grep -q "^; RUN:.llvm-objdump" $NAME && continue grep -q "^; RUN: opt." $NAME && continue 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/;\([A-Za-z0-9_-]\)\([A-Za-z0-9_-]\):\( \)$FUNC[:] \$/;\1\2-LABEL:\3$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 done This script catches a superset of the cases caught by the script associated with commit r186280. It initially found some false positives due to unusual constructs in a minority of tests; all such cases were disambiguated first in commit r186621. llvm-svn: 186624 2013-07-19 00:47:09 +02:00			`;CHECK-LABEL: vcast:`
