disassembled listing :

setIntrVSync:
    lui     v0,_hi(sectbase(.data))
    addiu   v0,v0,_lo(sectbase(.data))
    sll     a0,a0,2

source code :

static void (*cbIntrVSync[8])();

static void *setIntrVSync(int index, void (*callback)())
{
    void (*old)() = cbIntrVSync[index];

    if(callback != old)
        cbIntrVSync[index] = callback;

    return old;

reversed listing :
