[PATCH] x86: conditionalize x87 instructions and registers

Jan Beulich JBeulich@novell.com
Fri Jul 24 12:16:00 GMT 2009 
Just like with MMX, SSE, and AVX, FPU instructions and registers should
not be available for certain architecture settings, so that programmers
at least have the option of enforcing discipline on themselves.

Along with the core changes to accomplish this, the patch also adds
directives to selectively disable FPU, MMX, SSE, and AVX - with the
primary goal to have a way to make the respectively added registers
inaccessible (and available for use as normal symbols when not
requiring register prefixes).

gas/
2009-07-24  Jan Beulich  <jbeulich@novell.com>

	* tc-i386.c (cpu_arch): Add .8087, .287, .387, .no87, .nommx,
	.nosse, and .noavx.
	(cpu_flags_and_not): New.
	(set_cpu_arch): Check whether sub-architecture specified is a
	feature disable.
	(parse_real_register): Don't return floating point register
	when x87 functionality is disabled.

	* gas/i386/287.[ds]: New.
	* gas/i386/8087.[ds]: New.
	* gas/i386/no87.[ls]: New.
	* gas/i386/i386.exp: Run new tests.
	* gas/i386/att-regs.s: Also check FPU register access.
	* gas/i386/intel-regs.s: Likewise.
	* gas/i386/att-regs.d: Adjust expectations.

2009-07-24  Jan Beulich  <jbeulich@novell.com>

	* i386-dis.c (fgrps): Correct annotation for feni/fdisi. Add
	frstpm.
	* i386-gen.c (cpu_flag_init): Add FP enabling flags where needed.
	(cpu_flags): Add Cpu8087, Cpu287, Cpu387, Cpu687, and CpuFISTTP.
	(set_bitfield): Expand CpuFP to Cpu8087|Cpu287|Cpu387.
	* i386-opc.h (Cpu8087, Cpu287, Cpu387, Cpu687, CpuFISTTP):
	Define.
	(union i386_cpu_flags): Add cpu8087, cpu287, cpu387, cpu687,
	and cpufisttp.
	* i386-opc.tbl: Qualify floating point instructions by their
	respective CpuXXX flag. Fix fucom{,p,pp}, fprem1, fsin, fcos,
	and fsincos to be avilable only on 387. Fix fstsw ax to be
	available only on 287+. Add f{,n}eni, f{,n}disi, f{,n}setpm,
	and frstpm.
	* i386-init.h, i386-tbl.h: Regenerate.
