Re: [PATCH] enhance register parsing in .cfi_* handling (v2)


Hi Jan,

2008-02-11  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 ...
	(tc_x86_parse_to_dw2regnum): ... this.
	* dw2gencfi.c (tc_parse_to_dw2regnum): New, broken out of ...
	(cfi_parse_reg): ... this. Use tc_parse_to_dw2regnum. Adjust
	error handling.

	fields.
	(process_i386_registers): Process new (optional) fields.
	* i386-opc.h (reg_entry): Shrink reg_flags and reg_num to
	unsigned char. Add dw2_regnum.
	* i386-reg.tbl: Provide initializers for dw2_regnum for all
