This conversion 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/;\(.*\)\([A-Za-z0-9_]*\):\( *\)define\([^@]*\)@$FUNC\([( ]*\)\$/;\1\2-LABEL:\3define\4@$FUNC(/g" $TEMP
done
mv $TEMP $NAME
fi

; When inlining through a byval call site, the inliner creates allocas which may
|
|
; be used by inlined calls, so any inlined calls need to have their 'tail' flags
|
|
; cleared. If not then you can get nastiness like with this testcase, where the
|
|
; (inlined) call to 'ext' in 'foo' was being passed an uninitialized value.
