Documentation about inline psp assembler

[sauron_le_noir]

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 take a param and return the same param ok
but what is lv.s, mfv etc ... i can find this instruction in my mips asm documentation
what are the impact of the noreorder .
Does somebody have documentation about inline programming for the psp?
