Re: Report: compil error on OSX for target=i386

[Bean]

Hi,

I also encounter this problem with apple gcc 4.0, the fix is to replace:

asm volatile ("jmp *%2" : : "b" (0), "S" (real_mode_mem), "g"
(params->code32_start));

With:
  asm volatile ("movl %0, %%ecx" : : "m" (params->code32_start));
  asm volatile ("movl %0, %%esi" : : "m" (real_mode_mem));

  asm volatile ("xorl %%ebx, %%ebx" : : );
  asm volatile ("jmp *%%ecx" : : );
