Issue with shrink wrapping
Hello,
So, I have this testcase:
void f(int n, int x[]) {
if (n < 0)
return;
int a[n];
for (int i = 0; i < n; i++)
a[i] = x[n - i - 1];
for (int i = 0; i < n; i++)
x[i] = a[i] + 1;
}
that, compiled with -O1/-Os for AArch64 and X86, generates machine code,
which
fails to properly restore the stack pointer upon function return.
