Subject: [RFC] legacy_virtual_frame_pointer: SP_REGNUM might be a  pseudo-register
Date: Mon, 07 May 2007 21:48:00 -0000	[thread overview]
Message-ID: <20070507144824.1110b520@ironwood.lan> (raw)

Any comments on the patch below?

I found this change necessary to avoid internal errors in some gdb.trace
tests when running against the mips simulator.

	* arch-utils.c (legacy_virtual_frame_pointer): SP_REGNUM might
	be a pseudo-register; revise test accordingly.
