When emitting a cmp with 0 for a lowered select, mask out the high bits of the value carying the boolean condition, as their contents are undefined. This fixes rdar://10887484. llvm-svn: 151310

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

; CHECK: ldrb r[[R0:[0-9]+]], [r0]
[ARM] Allow CMPZ transforms even if the input has multiple uses. It looks like this got left in by accident in r289794; I can't think of any reason this check would be necessary. (Maybe it was meant to be a check that the AND has one use? But we check that a few lines earlier.) Differential Revision: https://reviews.llvm.org/D47921 llvm-svn: 334322
