33/* GDB's i386 target supports both the 32-bit Intel Architecture
34 (IA-32) and the 64-bit AMD x86-64 architecture. Internally it uses
35 a similar register layout for both.
36
37 - General purpose registers
38 - FPU data registers
39 - FPU control registers
40 - SSE data registers
41 - SSE control register
42
43 The general purpose registers for the x86-64 architecture are quite
44 different from IA-32. Therefore, gdbarch_fp0_regnum
45 determines the register number at which the FPU data registers
46 start. The number of FPU data and control registers is the same
47 for both architectures. The number of SSE registers however,
48 differs and is determined by the num_xmm_regs member of `struct
49 gdbarch_tdep'. */
