Update Transforms tests to use CHECK-LABEL for easier debugging. No functionality change.
...
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
done
mv $TEMP $NAME
fi
done

float comparison to double 'zero' constant can just be a float 'zero.'
...
InstCombine was incorrectly considering the conversion of the constant
zero to be unsafe.
We want to transform:
define float @bar(float %x) nounwind readnone optsize ssp {
%conv = fpext float %x to double
%cmp = fcmp olt double %conv, 0.000000e+00
%conv1 = zext i1 %cmp to i32
%conv2 = sitofp i32 %conv1 to float
ret float %conv2
}
Into:
define float @bar(float %x) nounwind readnone optsize ssp {
%cmp = fcmp olt float %x, 0.000000e+00 ; <---- This
%conv1 = zext i1 %cmp to i32
%conv2 = sitofp i32 %conv1 to float
ret float %conv2
}
