#include "harness.h" /* This problem occurs if a function is inlined. When its local variables get allocated space on the caller's (the function to which it is inlined) stack frame, they don't get 16-byte alignment even if they need it. Here's an example with a union (that's the first case I uncovered, but it's probably a general occurrence on inlining). */ #define N 10 /* adjust N = size of buffer to try to get bad alignment for inlined union */ #define DO_INLINE __attribute__ ((always_inline)) #define DONT_INLINE __attribute__ ((noinline)) static DO_INLINE int inline_me(vector signed short data) { union {vector signed short v; signed short s[8];} u; u.v = data; return u.s[7]; } static DONT_INLINE int foo(vector signed short data) { int c, buffer[N], i; c = inline_me(data); for (i=0; i<N; i++) { if (i == 0) buffer[i] = c; else buffer[i] = buffer[i-1] + c*i; } return buffer[N-1]; } static void test() { check(foo((vector signed short) ((vector unsigned char){1,2,3,4,5,6,7,8, 9,10,11,12,13,14,15,16})) == 0x2b4e0, "foo"); }
