<pre>Given the following test case:
------------------------------------------------------------------------
extern int printf(const char*, ...);
void foo(unsigned int i, int array[2]) __attribute__((noinline));
void foo(unsigned int i, int array[2]) {
printf("%d %d %d\n", i, array[0], array[1]);
}
int main() {
int array[2], i;
array[0] = 0;
array[1] = 1;
foo(0, array);
array[0] = 0;
array[1] = 1;
foo(1, array);
return 0;
}
---------------------------------------------------------------------------------
Target aarch64 and compile with "-O3" should produce:
0 0 1
1 0 1
Target aarch64 and compile with "-O3 -mllvm -enable-ipra" should incorrectly
produce:
0 0 1
1 -56 -128</pre>
