MIPS

[Wiz-IO]

I'm trying to port LiteOS for MIPS ( Microchip PIC32 )
can you explain in detail the function LOS_StartToRun()
or publish something like a C equivalent

IDA Pro deassembler give this code (approximately)
can you explain it in detail (???)

int LOS_StartToRun() {
int (* func)(int, int, int, int); // ????
OS_NVIC_SYSPRI2 = OS_NVIC_PENDSV_PRI; // ARM
g_bTaskScheduled = 1; // enable task schedule
__asm{ MSR.W CONTROL, #2 } // current stack pointer
g_stLosTask.pstRunTask = g_stLosTask.pstNewTask;
LOS_TASK_CB * V = g_stLosTask.pstNewTask;
g_stLosTask.pstNewTask->usTaskStatus |= OS_TASK_STATUS_RUNNING;
int * R = (int *) ((char ) V->pStackPointer + 100); // ???
int v7 = R[0];
int v8 = R[1];
int v9 = R[2];
int v10 = R[3];
func = (int () (int, int, int, int))R[6]; // ???
R += 26; // ???
__asm{ MSR.W PSP, R } // ARM Process Stack Pointer
__enable_irq(); // global
return func(v7, v8, v9, v10); // ???
}
