Should be fixed in glibc-2.8-3. Build available here:
Comment 2 Will Woods 2008-05-08 12:37:17 EDT
Can someone verify the fix, or give me a suggestion about how to verify it?
Comment 3 Jakub Jelinek 2008-05-08 12:51:32 EDT
It wasn't fixed, just worked around.  The real fix is being checked into GCC
today, so too late for F9.
Anyway, to verify cacoshl etc., just look for
in TESTING DETAILS in glibc 2.8-2 vs. 2.8-3 ppc64 build.log.
In 2.8-2 you will see a lot of errors, in 2.8-3 it isn't present (because the
test succeeded).
On ppc/ppc64 you need to ignore all the power6/ failures, because the lame koji
buildboxes don't have Altivec support, to get a clean testing you need to build
on Power6 or at least some Power box with Altivec ISA (e.g. G5).
Comment 4 Will Woods 2008-05-09 16:25:53 EDT
Thanks for the info, Jakub. Since we have a workaround in F9 I'm going to move
this off the blocker list.

I'm moving it to F9Target, under the assumption that the real fix will show up
as a F9 update.

Changing version to '9' as part of upcoming Fedora 9 GA.

The new gcc has long been deployed.  Closing.
