Subject: [PATCH 2/2] Arm64/gas: drop redundant feature prereqs
Date: Mon, 13 Feb 2023 09:12:45 +0100 [thread overview]
Message-ID: <c1e56cb2-a33f-59fd-a431-6a27460525cf@suse.com> (raw)
In-Reply-To: <85ea6922-fa11-0118-79d5-e69f1a66396d@suse.com>
Logic exists to deal with prereqs or prereqs, and in many cases
transitive prereqs are already not spelled out explicitly. Drop further
ones:
- FP is already a prereq to F16,
- SIMD and F16 are already prereqs to COMPNUM, and
- SVE2 and BFLOAT16 are already prereqs to SME.
