Subject: [djgpp/RFA] Fix crashes due to invalid numregs
Date: Thu, 30 Apr 2009 19:10:00 -0000	[thread overview]
Message-ID: <83iqkmdkkb.fsf@gnu.org> (raw)

This patch avoids internal_error's in the DJGPP port in places like
"finish", when GDB refills its regcache and tries to request too many
registers.

OK to commit?

	* i386-tdep.c (i386_go32_init_abi): Override the number of
	registers due to non-support of SSE.
