Subject: [PATCH 2/3] RISC-V: drop stray INSN_ALIAS flags
Date: Tue, 13 Sep 2022 15:03:25 +0200 [thread overview]
Message-ID: <348fe122-8296-716a-30ad-ce77746b9aa8@suse.com> (raw)
In-Reply-To: <7cb92a0b-d1ef-e3db-4773-0b6cd5183272@suse.com>
FENCE.TSO isn't an alias. ZIP and UNZIP in the long run likely are, but
presently they aren't. This fixes disassembly of these insns with
-Mno-aliases.
