 |
|
int test(int couleur)
{
int c;
__asm__ (
".set push\n"
".set noreorder\n"
"lv.s s000,%1\n"
"mfv %0, s000\n"
".set pop\n"
: "=&r"(c)
: "m"(couleur)
);
return (c);
}
this function just return the param couleur as the function result ok
but in my myps assembler documentation i don't find any trace of lv.s, mvfv etc...
where can i find documentation about inline assembler |

Because those ops are not standard mips, but special commands for the PSP-custom VFPU coprocessor.
There is no official documentation on that part. The only documentation for it is here:
