When compiling x11-wm/windowmaker-0.91.0-r1 with
sys-devel/gcc-3.3.5.20050130-r1
or sys-devel/gcc-3.3.6 with the -Os flag, the error below results. Removing
-Os
from the cflags allows the emerge to complete with no errors. I can't
reproduce
the error with sys-devel/gcc-3.3.4-r1 installed on a different system.
Reproducible: Always
Steps to Reproduce:
1.add -Os to your cflags
2.emerge windowmaker
Actual Results:

Could you humor me and try (with gcc-3.3.5/6):
CFLAGS="-Os -pipe"
and then if that works / fails:
CFLAGS="-Os -pipe -march=k6-2"
and then if that works / fails:
CFLAGS="-Os -pipe -fomit-frame-pointer"
... and report back if any of those succeeded / failed.
These don't work:
CFLAGS="-Os -march=k6-2 -pipe -fomit-frame-pointer"
CFLAGS="-Os -march=k6-2 -fomit-frame-pointer"
These work:
CFLAGS="-Os -fomit-frame-pointer"
CFLAGS="-O2 -march=k6-2 -pipe -fomit-frame-pointer"
CFLAGS="-march=k6-2 -pipe -fomit-frame-pointer"
CFLAGS="-Os -pipe"
CFLAGS="-Os -pipe -march=k6-2"
CFLAGS="-Os -pipe -fomit-frame-pointer"
This is a new gentoo system built from stage 1, all other packages build
correctly with the original CFLAGS.
It seems that removing any one flag (besides -pipe which shouldn't effect output
anyway) allows it to emerge correctly. Note that even replaing -Os with -O2 works.
I'll be transferring the setup to an actual k6-2 soon, and will post a comment
indicating it's success in compiling on that system soon.
The same error occurs when compiling on a real k6-2. That eliminates the
possibility of some strange amd64 issue.
wait wait -- are you running this on an amd64 machine or a k6-2? k6-2's are
the
early AMD chips...
Please confirm what machine this actually is ... maybe a `cat /proc/cpuinfo`
would do.
The error occurs on all the machines I have tried it on. That would be an
Athlon64 and a K6-2. I also tried it inside VMWare on the Athlon64 and got the
same error. Notice the original emerge info shows Athlon64.

Now -Os is filtered. Thanks for the feedback.
filter-flags is not appropriate, as it just removes the flag causing
windowmaker to be built without any -Ox optimization. Please use replace-flags
"-Os" "-O2" instead.
