Add clang.arc.used to ModuleHasARC so ARC always runs if said call is present in a module. clang.arc.used is an interesting call for ARC since ObjCARCContract needs to run to remove said intrinsic to avoid a linker error (since the call does not exist). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178369 91177308-0d34-0410-b5e6-96231b3b80d8 2013-03-29 21:15:23 +00:00			`; RUN: opt -objc-arc-contract -S < %s \| FileCheck %s`

Catch more CHECK that can be converted to CHECK-LABEL in Transforms for easier debugging. No functionality change. This conversion 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/;\(.\)\([A-Za-z0-9_]\):\( \)define\([^@]\)@$FUNC\([( ]*\)\$/;\1\2-LABEL:\3define\4@$FUNC(/g" $TEMP done mv $TEMP $NAME fi done git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186269 91177308-0d34-0410-b5e6-96231b3b80d8 2013-07-14 01:50:49 +00:00			`; CHECK-LABEL: define void @test0(`
