Subject: [PATCH v3 03/12] Makefile: Use common binary compilation rule
Date: Tue, 12 May 2026 15:52:47 +1000 [thread overview]
Message-ID: <20260512055256.1800449-4-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20260512055256.1800449-1-david@gibson.dropbear.id.au>
Each of our binaries (passt, passt.avx2, qrap and passt-repair) has a
separate Make rule instructing how to compile it, but they're all basically
identical. Combine these all into a single pattern rule, just using
different dependencies and variable overrides where necessary.
