OK, so I have a patch to fix the recursion depth in SCEV analysis but then we
hit
the next one in SLSR, in my case because with -O0 there's no tailcall performed
but even with -O2 we don't tailcall it.

This is the powers of simplify_subreg I guess. We're lucky it doesn't do

All,
this is my first post on these lists, so please bear with me.
My question is about gcc's __attribute__((aligned()). Please consider the
following code:
#include
typedef uint32_t uuint32_t __attribute__((aligned(1)));
uint32_t getuuint32(uint8_t p[]) {
return *(uuint32_t*)p;
}
