I added a replace-flags -O3 -O2 to the ebuild locally, but i suspect there
isn't much to be done except to be aware of the problem if we are using gcc 3.4
Exactly, the code is already hand-tuned to get the most of x86's reduced
register space. I don't see the flag handling in the ebuild actually, you can
commit it.
i still have this problem,the ebuild also has no replace-flags....
It should have, i'll add it tomorrow, in the mean time you can build with
CFLAGS="".
I added strip-flags which removes -O3 and other quite untested flags.
"strip-flags" doesn't remove -O3. Still the same ;)
Use "replace-flags -O? -O2"
I fixed that in CVS, now closing the bug :)
