Description brankob 2014-07-16 18:11:30 UTC
new gcc version.

Existing ebuild for 4.9.0 works fine for 4.9.1, or so it seems at this point.
I have adapted existing gcc-4.9.0-patches for it.

Basically all I needed to do is delete last few patchfiles in it, as they were already applied upstream.

Deleted patches:


93_all_pr60971-wrong-code.patch
94_all_pr60902-ffmpeg-miscompile.patch
95_all_pr60960-wrong-code.patch
96_all_pr59952-avx2-no-rtm.patch
97_all_pr60965-devirt-placement-new.patch

I have attached  whole thing just in case.

i'm pretty sure they know about it.
Comment 3 brankob 2014-07-16 19:30:15 UTC
Well, it's not in the tree.

So their awareness of it is of no use to me.

I wanted to try it, adapted existing patch and compiled it.

And now there is a bug, which can be found by others to try it before 4.9.1 appears int the tree. Which can take a while.
Comment 5 brankob 2014-07-17 23:35:16 UTC
It doesn't apply here.

I haven't requested anything, just posted a patch for those that would like to play.

This isn't the first time that maintainers took far more to publish their ebuild.

thanks @Branko !


we/devs also should make sure that the following patch makes it into the in-tree gcc 4.9.1 (or even 4.9.0):

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61144

producing wrong code is a serious issue
Comment 7 David Heidelberg (okias) 2014-07-26 20:49:44 UTC
please also include this fix for kernel (with -Os) + gcc (4.5.0-4.9.1)

File a bug so we have a record of it please.

Also mariadb seems to be affected by a bug in 4.9.0 version.
See comment #3 in bug #518580: https://bugs.gentoo.org/show_bug.cgi?id=518580#c3

We'll wait until something is committed upstream.
