Subject: [gcc r13-204] Remove GIMPLE restriction of ! using match.pd patterns
Date: Mon,  9 May 2022 11:42:53 +0000 (GMT)	[thread overview]
Message-ID: <20220509114253.1A56A3838002@sourceware.org> (raw)

commit r13-204-g93416de0cb72358b95a96fa4341b7b93a6805842
Author: Richard Biener <rguenther@suse.de>
Date:   Mon May 9 11:50:55 2022 +0200

    Remove GIMPLE restriction of ! using match.pd patterns
    
    This removes #if GIMPLE guards around patterns using ! which is
    now also provided in the GENERIC implementation.
