Subject: [PATCH] RFC: Fix GCSE bug optimization/11440 (3.3 regression)

Hi,

this patch against the 3_3-branch fixes the testcase for me (no completed
bootstrap/regtest so far). I'm not 100% sure if it's the right place to reject
the note, but it looks reasonable to me. And do I need to reject
STRICT_LOW_PART and SUBREG too?

Franz.

	* gcse.c (try_replace_reg): Don't attach notes to ZERO_EXTRACT or
	SIGN_EXTRACT SETs.
