Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though. Patch by Ron Ofir. llvm-svn: 188173

Avoid NEON SP-FP unless unsafe-math or Darwin NEON is not IEEE 754 compliant, so we should avoid lowering single-precision floating point operations with NEON unless unsafe-math is turned on. The equivalent VFP instructions are IEEE 754 compliant, but in some cores they're much slower, so some archs/OSs might still request it to be on by default, such as Swift and Darwin. llvm-svn: 177651

; NEON is not fully IEEE 754 compliant, unless unsafe-math is selected.

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
