IRQ and xTaskResumeFromISR

I’m using ARM7 based board without Interrupt Controller like on LPCxxx.
I have only one task suspends yourself:

task1( void *pvParameters ){
    int i;
    for (;;){
        i++;
        vTaskSuspend(NULL);
        i++;
    }
     }

I have declaration of IRQ handler (not ISR task) like below:

_interruptHandler()   __attribute__ ((naked))
_interruptHandler(){
     portENTER_SWITCHING_ISR();
     if( IRQ1 ){
        eventTeack++;
        xYieldReq=xTaskResumeFromISR(xhTask1);
        if(xYieldReq== pdTRUE)
           vTaskSwitchContext();
     }
      portEXIT_SWITCHING_ISR();
}

I’ve tried use portEXIT_SWITCHING_ISR but these macrosses are only for ISR’s task.

How exactli can I perform resumming within IRQ hendler?

Should this not be:

_interruptHandler() __attribute__ ((naked))
_interruptHandler(){
portENTER_SWITCHING_ISR();
int xYieldReq = 0;
if( IRQ1 ){
eventTeack++;
xYieldReq=xTaskResumeFromISR(xhTask1);
}
portEXIT_SWITCHING_ISR(xYieldReq); 
}

xYieldReq is a parameter to portEXIT_SWITCHING_ISR.

Alternatively just save the context of the task on entry to the IRQ using portSAVE_CONTEXT and restore it on exit using portRESTORE_CONTEXT, then call vTaskSwitchContext as you were.
