Description Denise Dumas 2009-08-26 21:16:24 UTC

Description of problem:
compat-gcc-34 fails because this compiler doesn't seem to know about z9/z10 optimizations, we probably just need to remove those from CFLAGS:
  https://brewweb.devel.redhat.com/getfile?taskID=1943907&name=build.log


for details, talk with Karsten Hopp on #fedora-s390x
This is blocking the RHEL6 Alpha 2

Comment 2 Karsten Hopp 2009-08-28 17:36:09 UTC

Easily fixable by trimming the OPT_FLAGS similar to what we already do for the other archs.
The only question is if we should use -march=z900 or -march=z990.
I've already successfully tested a build with these modifications at
http://brewweb.devel.redhat.com/brew/taskinfo?taskID=1948114

Comment 3 Jakub Jelinek 2009-08-29 10:08:54 UTC

We should use the same options as were used in RHEL4 (where gcc 3.4 was the primary compiler), as that's what was tested most.  I believe we didn't pass any special -march= nor -mtune= for s390/s390x at that time, so we should just strip it from OPT_FLAGS on these arches.

Comment 4 Karsten Hopp 2009-08-31 13:40:35 UTC

fixed in compat-gcc-34-3.4.6-18

Comment 5 Karsten Hopp 2009-08-31 13:40:46 UTC

fixed in compat-gcc-34-3.4.6-18

Comment 6 releng-rhel@redhat.com 2009-10-28 15:50:54 UTC

Fixed in 'compat-gcc-34-3.4.6-18', included in compose 'RHEL6.0-20091027.3'.
Moving to ON_QA.

Comment 7 Michal Nowak 2009-11-26 15:04:17 UTC

Verified that compat-gcc-34-3.4.6-18 build for s390x another proof that compat-gcc-34-3.4.6-18 can be build is here: http://download.devel.redhat.com/brewroot/packages/compat-gcc-34/3.4.6/18/. Also had a look at changes 13 v. 18 in CVS and the changes are those proposed in this BZ.

Comment 8 releng-rhel@redhat.com 2010-07-02 18:55:55 UTC

Red Hat Enterprise Linux Beta 2 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
