• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Raúl Porcel (RETIRED) 2009-08-28 15:58:39 UTC]

Looks like it sigbuses. Build log to follow...

Steps to reproduce:
1. Extract fresh stage3 tarball
2. Add ACCEPT_KEYWORDS="~sparc" to /etc/make.conf
3. emerge gcc
4. gcc-config sparc-unknown-linux-gnu-4.4.1; source /etc/profile, etc...
5. emerge -evuDN world

Portage 2.1.6.13 (default/linux/sparc/2008.0, gcc-4.4.1, glibc-2.8_p20080602-r1, 2.6.28-gentoo-r5 sparc64)

It's PR37344

[Comment 3 Raúl Porcel (RETIRED) 2009-11-03 16:44:18 UTC]

same with 4.4.2

[Comment 4 Raúl Porcel (RETIRED) 2010-01-08 20:03:32 UTC]

bumb?

[Comment 5 SpanKY 2010-01-08 23:16:41 UTC]

there's no patch here and there's no clear patch listed upstream, just ideas

try the patch upstream and see if it fixes the sparc problem, then post it here so it can be included

[Comment 7 Raúl Porcel (RETIRED) 2010-06-08 18:49:24 UTC]

Mike,

This happens when using STAGE1_CFLAGS=-O . Works with -O2, could we make an exception on sparc and use -O2 on STAGE1_CFLAGS on gcc-4.4 and above? I don't think this is going to get fixed soon...

[Comment 8 SpanKY 2010-06-08 22:10:52 UTC]

i hate this BS.  i'm guessing you want something like:
+    elif tc_version_is_at_least 4.4 && [[ ${CTARGET} == sparc*linux* ]] ; then
+        STAGE1_CFLAGS=${STAGE1_CFLAGS-"-O2"} #283041
     else
         STAGE1_CFLAGS=${STAGE1_CFLAGS-"-O"}
     fi

[Comment 9 Ryan Hill (RETIRED) 2010-07-07 17:02:19 UTC]

what about STAGE1_CFLAGS=-O0?
