Force a fixed unroll count on the target independent tests. This should fix clang-native-arm-cortex-a9. Thanks Renato. llvm-svn: 171582

Add support for loops that don't start with Zero. This is important for loops in the LAPACK test-suite. These loops start at 1 because they are auto-converted from fortran. llvm-svn: 167084

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 llvm-svn: 186268

TBAA: remove !tbaa from testing cases if not used. This will make it easier to turn on struct-path aware TBAA since the metadata format will change. llvm-svn: 180796
