0002-Allow-constant-MEMs-through-calls.patch

Subject: 0002-Allow-constant-MEMs-through-calls.patch
References: <4C18F225.2040509@codesourcery.com>

The function gcse.c: compute_transpout() is responsible for filtering out expressions that do not survive function calls. Certain kinds of memory references, e.g., references to read-only memory can safely be propagated through calls. This patch improves compute_transpout() to allow that.

OK to apply?

Thank you,
