ARM: yet another round of ARM test clean ups llvm-svn: 205586
2014-04-04 07:47:24 +08:00
; RUN: llc -mtriple=thumb-eabi -mcpu=arm1156t2-s -mattr=+thumb2 %s -o - | FileCheck %s
Make tBX_RET and tBX_RET_vararg predicable. The normal tBX instruction is predicable, so there's no reason the pseudos for using it as a return shouldn't be. Gives us some nice code-gen improvements as can be seen by the test changes. In particular, several tests now have to disable if-conversion because it works too well and defeats the test. llvm-svn: 134746

; If-conversion defeats the purpose of this test, which is to check CBZ
Improve test cases from r134746. Use memory barriers to force if-conversion off for these tests instead of the internal llc command line option ifcvt-limit. llvm-svn: 134986

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
