This update was done with the following bash script:
find test/Transforms -name "*.ll" | \
while read NAME; do
echo "$NAME"
if ! grep -q "^; *RUN: *llc" $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

; Test LSR's ability to prune formulae that refer to nonexistant
|
|
; AddRecs in other loops.
|
|
;
|
|
; Unable to reduce this case further because it requires LSR to exceed
|
|
; ComplexityLimit.
|
|
;
|
|
; We really just want to ensure that LSR can process this loop without
|
|
; finding an unsatisfactory solution and bailing out. I've added
|
|
; dummyout, an obvious candidate for postinc replacement so we can
|
|
; verify that LSR removes it.
