Hi 2. I have compile my qemu to --target-list=x86_64-softmmu , in gdb, why the registers is 32 bits?
(gdb) i reax 0x0 0ecx 0xf7 247edx 0x19a804 1681412ebx 0x137 311esp 0x19a0d0 0x19a0d0ebp 0x9000 0x9000esi 0x19a120 1679648edi 0x0 0eip 0x1098b7 0x1098b7eflags 0x246 582cs 0x10 16ss 0x18 24ds 0x18 24es 0x18 24fs 0x2b 43gs 0x18 24

The remote gdb protocol does not yet include extended registers, so you
need to fall back to the QEMU monitor. Type "monitor info registers".
