Subject: * config/i386/tm-i386.h (REGISTER_SIZE): Remove define.
X-Git-Tag: pre-no-this~1943
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9ab73e7218fee22528e1af0c76b747be969b637b;p=pf3gnuchains%2Fpf3gnuchains4x.git

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


* i386-tdep.c (i386_gdbarch_init): Tewak
