Ext: support the ‘pragma’ that makes the fiq/irq handler without vector setting.

Syntax :

#pragma function=interrupt_fiq_novector

#pragma function=interrupt_irq_novector

Ex> making the fiq handler without vector

#pragma function=interrupt_fiq_novector

void fiq_handler(void) {

}

Fixed: When variable’s definition follows the definition of function and there is the

function’s declaration, sorting variables for the address optimization is incorrect. It

occurs only over the optimization level 1.

Ex>

#include <stdio.h>

int a0;

char c4;

void foo(void);

void main(void); // declaration

void main(void) // body of function defined before the definition of variables a2

{

a0 = 1;

c4 = 2;

foo(); // a2 = 0;

if (c4 != 2) printf("fail\n");

}

int a2; // When a variable’s definition follows the definition of function

// and there is the function’s declaration,

// sorting variables for the address optimization is incorrect.

void foo(void)

{

a2 = 0;

}
