quick and dirty patch to reduce code size
Here's a patch which doesn't mess up the stack pointer update in the epilogue.
The code size output is broken on mainline, so here's what I use:
$ gcc/xgcc -Bgcc/ -W -Wall ~/pr11180.c -S -dp -o /dev/stdout -O2 | awk
'match($0, /\[length = ([[:digit:]]+)\]/, field) { sum += field[1]; } END {
print sum; }'
27
Compare that to unpatched mainline:
$ gcc/xgcc -Bgcc/ -W -Wall ~/pr11180.c -S -dp -o /dev/stdout -O2 | awk
'match($0, /\[length = ([[:digit:]]+)\]/, field) { sum += field[1]; } END {
print sum; }'
