extern void abort (); extern void exit (int); #ifndef __thumb__ /* There used to be a couple of bugs in the ARM's prologue and epilogue generation for ISR routines. The wrong epilogue instruction would be generated to restore the IP register if it had to be pushed onto the stack, and the wrong offset was being computed for local variables if r0 - r3 had to be saved. This tests for both of these cases. */ int z = 9; int bar (void) { return z; } int foo (int a, int b, int c, int d, int e, int f, int g, int h) { volatile int i = (a + b) - (g + h) + bar (); volatile int j = (e + f) - (c + d); return a + b + c + d + e + f + g + h + i + j; } int foo1 (int a, int b, int c, int d, int e, int f, int g, int h) __attribute__ ((interrupt ("IRQ"))); int foo1 (int a, int b, int c, int d, int e, int f, int g, int h) { volatile int i = (a + b) - (g + h) + bar (); volatile int j = (e + f) - (c + d); return a + b + c + d + e + f + g + h + i + j; } #endif int main (void) { #ifndef __thumb__ if (foo (1, 2, 3, 4, 5, 6, 7, 8) != 32) abort (); if (foo1 (1, 2, 3, 4, 5, 6, 7, 8) != 32) abort (); #endif exit (0); }
