im a patch newbie, sorry.. can someone add these 2 lines to
/allegro/src/i386/icpu.c
and also add the defines to the list in /include/allegro/system.h (approx
line 110)
line123: /* SSE has MMX+ included */
line124: cpu_capabilities |= (reg[3] & 0x2000000 ? CPU_SSE | CPU_MMXPLUS : 0);
line125: cpu_capabilities |= (reg[3] & 0x4000000 ? CPU_SSE2 : 0);
line126: cpu_capabilities |= (reg[3] & 0x8000 ? CPU_CMOV : 0);
// AJ addition, add this line here!!!
cpu_capabilities |= (reg[3] & 0x40000000 ? CPU_IA64 : 0);
}
_i_get_cpuid_info(0x80000000, reg);
if ((unsigned long)reg[0] > 0x80000000) {
_i_get_cpuid_info(0x80000001, reg);
cpu_capabilities |= (reg[3] & 0x80000000 ? CPU_3DNOW : 0);
// AJ addition, add this line also.
cpu_capabilities |= (reg[3] & 0x20000000 ? CPU_AMDx86_64 : 0); // bit29,
AMD specific: x86-64
/* Enhanced 3DNow! has MMX+ included */
cpu_capabilities |= (reg[3] & 0x40000000 ? CPU_ENH3DNOW | CPU_MMXPLUS : 0);
