Bug 309279 – sys-devel/gcc-4.3.4 fails to build on alpha with PR42113 fix

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Raúl Porcel (RETIRED) 2010-03-13 17:05:01 UTC]

From a fresh *STABLE* stage3, build log as follows...

The culprit is the 02_all_gcc-4.3-alpha-PR42113.patch patch, excluding it it compiles successfully.

The patch is used in the 4.3, 4.4, and 4.5 branches and is included in 4.4.3 already.

The problem is, apparently, that we're missing some other necessary patch from 4.3 SVN. I'll see if I can track it down.

[Comment 3 Raúl Porcel (RETIRED) 2010-03-20 11:06:02 UTC]

@toolchain: could we exclude the patch meanwhile?

Thanks

The problem with that is that the patch fixes internal compiler errors itself. So gcc will compile, but rsync and libperl won't.

(Sorry I haven't had time to figure out what patches we need to make this compile.)

yes, i can vouch for the rsync ICE.  i saw the same problem with 4.4.2 and upgrading to 4.4.3 fixed rsync building.

I tracked the commits done to the gcc-4_3-branch until the patch from PR42113. This patch replaces 02_all_gcc-4.3-alpha-PR42113.patch , since that patch is included in this one as well.

Thanks

i would want to extract some info from each svn commit to put into the patch header ...

Nope. Looks great to me.

Thanks a _ton_ armin76! I owe you a beer, whenever I come to Spain. :D

Ugh. Apparently there is another fix to this:

http://gcc.gnu.org/ml/gcc-patches/2010-03/msg01146.html

Please include that as well after we test it.

[Comment 12 Mark Loeser (RETIRED) 2010-03-25 20:34:27 UTC]

Excluded in the ebuild until we have a full patch.

[Comment 13 Raúl Porcel (RETIRED) 2010-04-05 13:44:49 UTC]

Reducing priority as this isn't a problem now.

I'd vote for waiting for a 4.3.5 release, to be honest...at least i'm not going to bother to fix this, with the small improvement it gives(fixing -O3).

[Comment 14 Raúl Porcel (RETIRED) 2010-05-29 15:30:15 UTC]

Since 4.4.3 is supposed to go to stable, can we forget about this bug?

[Comment 15 SpanKY 2010-06-08 22:11:45 UTC]

there is a 4.3.5 release which i'm working on, so i'll close this once i bump

[Comment 16 SpanKY 2010-06-10 03:07:59 UTC]

gcc-4.3.5 is now in the tree
