From a60de03c6170ebd45927e318164e2306028df86d Mon Sep 17 00:00:00 2001 From: Jan Beulich <jbeulich@novell.com> Date: Wed, 13 Feb 2008 10:14:40 +0000 Subject: gas/ 2008-02-13 Jan Beulich <jbeulich@novell.com> * config/tc-i386.c (allow_pseudo_reg): New. (parse_real_register): Check for NULL just once. Allow all register table entries when allow_pseudo_reg is non-zero. Don't allow any registers without type when allow_pseudo_reg is zero. (tc_x86_regname_to_dw2regnum): Replace with ... (tc_x86_parse_to_dw2regnum): ... this. (tc_x86_frame_initial_instructions): Adjust for above change. * config/tc-i386.h (tc_regname_to_dw2regnum): Remove. (tc_parse_to_dw2regnum): New. (tc_x86_regname_to_dw2regnum): Replace with ...
