[PATCH] Add a TARGET_GEN_MEMSET_VALUE hook
- From: "H.J. Lu" <hongjiu dot lu at intel dot com>

- Subject: [PATCH] Add a TARGET_GEN_MEMSET_VALUE hook
- Authentication-results: sourceware.org; auth=none
- Reply-to: "H.J. Lu" <hjl dot tools at gmail dot com>
builtin_memset_gen_str returns a register used for memset, which only
supports integer registers. But a target may use vector registers in
memmset. This patch adds a TARGET_GEN_MEMSET_VALUE hook to duplicate
QImode value to mode derived from STORE_MAX_PIECES, which can be used
with vector instructions. The default hook is the same as the original
builtin_memset_gen_str. A target can override it to support vector
instructions for STORE_MAX_PIECES.
Tested on x86-64 and i686. Any comments?
H.J.
