Bug 108687 – sys-apps/busybox/busybox-1.00-r4 fails to compile on ppc with hardened gcc profile

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description nixnut (RETIRED) 2005-10-09 22:43:10 UTC]

Using the hardened gcc profile emerging busybox causes an internal compiler error.
After switching to the vanilla profile busybox compiler without problems.

As requested

[Comment 2 SpanKY 2005-10-10 07:04:07 UTC]

not a bug in busybox

[Comment 3 Olivier Castan 2005-10-11 01:17:09 UTC]

Same bug here. Any recipe to rebuild a clean toolchain on PPC (like bug #79852
for x86) ?

[Comment 4 Lars Weiler (RETIRED) 2006-01-21 08:55:52 UTC]

Another ppc/hardened bug?  Probably we should keyword and group them...

[Comment 5 Joe Jezak (RETIRED) 2006-02-17 09:19:03 UTC]

This is a hardened bug, re-assigning to them.

[Comment 6 Kevin F. Quinn (RETIRED) 2006-02-17 11:51:21 UTC]

Looks like another -fno-strict-aliasing problem.  Why do ppc people like to put this in their CFLAGS?

(In reply to comment #6)
> Looks like another -fno-strict-aliasing problem.

No it doesn't.  Just confirmed the same behaviour with the hardened compiler with standard make.default settings (busybox-1.1.0; the relevant source file hasn't changed much).

The combination that fails is -fstack-protector and -funit-at-a-time (which is enabled at -O2, -Os and higher).  It's a start, anyway.

[Comment 8 solar (RETIRED) 2009-07-24 02:37:15 UTC]

Please reopen with upstream if this is still a problem.

[Comment 9 Gordon Malm (RETIRED) 2009-07-24 03:31:41 UTC]

nixnut if still having problems please also file a new hardened+ppc+busybox bug here so we're aware and for tracking against any upstream bug report/URL.  Thanks.
