Stephen Lin	d24ab20e9b	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	2013-07-14 06:24:09 +00:00
Nadav Rotem	a136939fa9	Reapply r162160 with a fix: Optimize Arith->Trunc->SETCC sequence to allow better compare/branch code. ... llvm-svn: 162172	2012-08-18 17:53:03 +00:00
Nadav Rotem	c324af609e	Revert r162160 because it made a few buildbots fail. ... llvm-svn: 162164	2012-08-18 05:02:36 +00:00
Nadav Rotem	2cb14a5c4b	The X86 backend has a number of optimizations for SETCC nodes which use ... arithmetic instructions. However, when small data types are used, a truncate node appears between the SETCC node and the arithmetic operation. This patch adds support for this pattern.
