Subject: [PATCH] Fix ppc* libSegFault.so register dump
Date: Fri, 15 Sep 2006 22:52:00 -0000	[thread overview]
Message-ID: <20060915225144.GJ4556@sunsite.mff.cuni.cz> (raw)

Hi!

For ppc32 this just removes '\0' character that has been printed after
the register dump and before the backtrace.
For ppc64 libSegFault.so printed complete garbage.

2006-09-16  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc32/register-dump.h (register_dump): Don't
	write '\0' to the fd.
	* sysdeps/mach/hurd/powerpc/register-dump.h (register_dump): Likewise.
	* sysdeps/powerpc/powerpc64/register-dump.h (register_dump): Likewise.
	Change regs to unsigned long pointer from unsigned int, fix fscr offset.
