Description Pascal de Bruijn 2003-08-13 10:22:27 UTC

python-fcksum didn't emerge with the following
CFLAGS="-march=k6 -O2 -fomit-frame-pointer -funroll-loops"

after I removed the -funroll-loops it did emerge!

This seems to be a known upstream bug with gcc-3.2.x. 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=8412 
If using -funroll-loops the workaround given is to use -march=i586

pascal, can you please attach the output of emerge info?

i'm using gcc 3.2.3 and -march=k6 -funroll-loops -O2 works for me. can you also attach the output of the compile error?

brandy, thanks for your link :)

hrmm .. well, according to the bug, 3.3 and newer 3.2.3 has the compiler
bug fixed. 

since the reporter didn't supply emerge info, i don't think we can do much
about it.
