Where is source code of isr_setinterruptvector?

Hi
I have trouble with timer1,3.
The interrupt timer1 execute is to slowly (~=400KHz on P5.2pin) and doesn't 
depend of value TH1 and TL1.
The interrupt time of timer1 depend of _nop_() , P5 &=~4 and TH1=0xFF (body 
of interrupt function)
I  think one instruction for examples one NOP operation on TINI400 with 
CLOCK = 14.7MHz X 4 take time = 1/14.7MHz or am I wrong ?

Where is i can get source code of isr_setinterruptvector function for KEIL?

void myinterrupt(void) interrupt 3
{
		P5 &= ~4;
		_nop_ ();
		_nop_ ();
		_nop_ ();
		_nop_ ();
		_nop_ ();
		_nop_ ();
		_nop_ ();
		_nop_ ();
		TH1=0xFF;
		TL1=0xFF;
		P5 |= 4; //ET0 = 0;
}

Why Dallas doesn't support the sdcc compiler ?
No rom_init,rom_sock library for sdcc compiler.
