Maybe this is a little unnecesary since its amd64 and should support all extra
flags (at the end its a patch to the makefile), and the only file broken is
to get the configure arguments, cpu detection inside the mplayer binary works
perfectly
on TOOLS/cpuinfo.c:
static cpuid_regs_t
cpuid(int func) {
cpuid_regs_t regs;
#define CPUID ".byte 0x0f, 0xa2; "
asm("push %%ebx; "
"movl %4,%%eax; " CPUID
"movl %%eax,%0; movl %%ebx,%1; movl %%ecx,%2; movl %%edx,%3; "
"pop %%ebx"
: "=m" (regs.eax), "=m" (regs.ebx), "=m" (regs.ecx),
"=m" (regs.edx)
: "g" (func)
: "%eax", "%ecx", "%edx");
printf(""); // **** NOTE this *extra* printf()
return regs;
}
with the printf:
# TOOLS/cpuinfo
vendor_id : AuthenticAMD
cpu family : 15
model : 12
stepping : 0
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 cflsh mmx fxsr sse sse2 mmxext 3dnowext 3dnow k6_mtrr
cpu MHz : 2000.021
model name : AMD Athlon(tm) 64 Processor 3000+
w/o the printf()
# TOOLS/cpuinfo
vendor_id :
model name : Unknown CPU
why this works, i have no idea. Maybe its something to do with the registers,
etc.
I won't try to debug it further since we already know the flags of the CPU
(and the printf seems to fix the problem anyways)
this is a commitable patch to the makefile:
