ARM: fixup more tests to specify the target more explicitly This changes the tests that were targeting ARM EABI to explicitly specify the environment rather than relying on the default. This breaks with the new Windows on ARM support when running the tests on Windows where the default environment is no longer EABI. Take the opportunity to avoid a pointless redirect (helps when trying to debug with providing a command line invocation which can be copy and pasted) and removing a few greps in favour of FileCheck. llvm-svn: 205541

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

Codegen: Tail Merge: Be less aggressive with special cases. This change makes it possible for tail-duplication and tail-merging to be disjoint. By being less aggressive when merging during layout, there are no overlapping cases between tail-duplication and tail-merging, provided the thresholds are disjoint. There is a remaining TODO to benchmark the succ_size() test for non-layout tail merging. llvm-svn: 278265
