Subject: [PATCH] tree-optimization/107095 - fix typo in .MASK_STORE DSE handling
Date: Fri, 30 Sep 2022 12:50:03 +0200 (CEST)	[thread overview]
Message-ID: <20220930105003.7C8A813776@imap2.suse-dmz.suse.de> (raw)

We were using the size of the mask argument rather than the data
argument for the ao_ref.

Bootstrap and regtest running on x86_64-unknown-linux-gnu.

	PR tree-optimization/107095
	* tree-ssa-dse.cc (initialize_ao_ref_for_dse): Use data arg
	for .MASK_STORE size.
