I added the above option to gcc and did core-image-sato build to see
if I would gain some compile time performance.
http://git.openembedded.org/openembedded-core-contrib/commit/?h=kraj/gcc-4.7&id=2d7004457a23c6c952f81e55b8ab7e3cc69bd905
The results were not very astounding but I do see some improvement
original
real 102m50.131s
user 437m7.463s
sys 67m29.237s
with --enable-checking=release
real 102m19.762s
user 439m41.749s
sys 66m10.376s
This was using shared state for native packages but cross packages
were all built too. overall gain in pecents will be more since we
would then
subtract the time it took to compile the cross tools.
This patch is for gcc-4.7 recipes as of now.
Thanks
