Hi , I am looking for some helps on the issue i have in my project after this change for the compiler.

typedef void (*callback_t)(uint32_t icciar, void * context);

callback_t callee1;
void _ _attribute__((interrupt("IRQ"))) __cs3_isr_irq() {

  callee1(icciar , context);

}

the above code gives me the expected error " call to function without interrupt attribute could clobber interruptee's VFP registers"

below is my attempt
===================

typedef void _ _attribute__((interrupt("IRQ")))  (*callback_t)(uint32_t icciar, void * context);

callback_t _ _attribute__((interrupt("IRQ"))) callee1;
void _ _attribute__((interrupt("IRQ"))) __cs3_isr_irq() {

  callee1(icciar , context);

}

However, it is still giving me the error "" call to function without interrupt attribute could clobber interruptee's VFP registers" 
What is the best way to modify the code for this compiler change ?

thanks all in advance !!
