* config/i386/tm-i386.h (REGISTER_SIZE): Remove define.

Browse Source 
(NUM_GREGS, NUM_FREGS, NUM_SSE_REGS): Remove defines.
(FP_REGNUM, SP_REGNUM, PC_REGNUM, PS_REGNUM): Remove defines.
(FP0_REGNUM): Remove define.
(MAX_REGISTER_RAW_SIZE, MAX_REGISTER_VIRTUAL_SIZE,
MAX_REGISTER_VIRTUAL_SIZE): Remove define.
(i386_register_virtual_size): Remove protoype.
* i386-tdep.c (i386_register_virtual_size): Removed.
(i386_extract_return_value, i386_store_return_value): Use
FP0_REGNUM instead of NUM_FREGS to determine whether the
floating-point registers are available.
(i386_gdbarch_init): Tweak FIXME about FPU registers.
Adjust for removal of macros mentioned above.

/* This register file is parameterized by two macros:
HAVE_I387_REGS --- register file should include i387 registers
HAVE_SSE_REGS --- register file should include SSE registers
If HAVE_SSE_REGS is #defined, then HAVE_I387_REGS must also be #defined.
However, GDB code should not test those macros with #ifdef, since
that makes code which is annoying to multi-arch. Instead, GDB code
should check the values of NUM_GREGS, NUM_FREGS, and NUM_SSE_REGS,
which will eventually get mapped onto architecture vector entries.
It's okay to use the macros in tm-*.h files, though, since those
files will get completely replaced when we multi-arch anyway. */
