Hi,
The inlininer likes to recreate some MEM_REF, it copies most of the
bits (TREE_THIS_NOTRAP, TREE_THIS_VOLATILE, etc.) but forgets about
TREE_SIDE_EFFECTS. This causes the strlen optimization to think the
memory store does not have a side effects.
OK? Bootstrapped and tested on x86_64-linux

Hi,
The problem here is the strlen optimization tries to remove a null
character store as we already have done it but it does it for a
volatile store which is not a valid thing to do.
This patch fixes the problem by ignoring statements which have
volatile operands.
OK? Bootstrapped and tested o
