binutils-gdb/gas/config/tc-i386.h
Jan Beulich a60de03c61 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 ...
	(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.

gas/testsuite/
2008-02-13  Jan Beulich  <jbeulich@novell.com>

	* gas/cfi/cfi-i386.s: Add code testing use of all registers.
	Fix a few comments.
	* gas/cfi/cfi-x86_64.s: Likewise.
	* gas/cfi/cfi-i386.d, gas/cfi/cfi-x86_64.d: Adjust.

opcodes/
2008-02-13  Jan Beulich  <jbeulich@novell.com>

	* i386-gen.c (process_i386_registers): Process new fields.
	* i386-opc.h (reg_entry): Shrink reg_flags and reg_num to
	unsigned char. Add dw2_regnum and Dw2Inval.
	* i386-reg.tbl: Provide initializers for dw2_regnum. Add pseudo
	register names.
	* i386-tbl.h: Re-generate.
