Bug 72755 – sys-kernel/ppc64-headers are buggy

• Product: Gentoo Linux
• Status: VERIFIED WONTFIX

[Description Jocelyn Mayer 2004-11-28 12:42:07 UTC]

Please update sys-kernl/ppc64-headers.
There is at least one bug in /usr/include/asm/ptrace.h
Here, we find:
#define PT_FPSCR (PT_FPR0 + 32 + 1)
when it's defined with:
#define PT_FPSCR (PT_FPR0 + 32) in recent kernels.

This prevent gdb to work well as it gets EIO while trying to retrieve this register.

I'm running a linux-2.6.10-rc2 kernel with patches to make it run on the new Imac G5. Refer to http://bugs.gentoo.org/show_bug.cgi?id=68970 for more infos on the used patchset (but I can assure it changes nothing to ptrace behaviour).

Greetings,

sys-kernel/ppc64-headers shouldn't be in use anymore.  linux26-headers and linux-headers (for 2.4 and 2.6 based headers) is what we've been steering people towards.

[Comment 2 Jocelyn Mayer 2004-12-14 14:00:00 UTC]

Hi,

Thanks for the tip...
I checked that sys-kernel/linux26-headers merged well on my Imac and is safe from this bug.
May this packages be deleted or masked ?

[Comment 3 Markus Rothe (RETIRED) 2005-02-22 06:23:41 UTC]

ppc64-headers will be moved to package.mask and then they will be removed in a
few weeks.
