Subject: [PATCH bpf-next v2 2/2] selftests/bpf: Enable gotox tests for riscv64
Date: Mon, 28 Sep 2026 10:21:09 +0800	[thread overview]
Message-ID: <20260928022109.1093-3-cp0613@linux.alibaba.com> (raw)
In-Reply-To: <20260928022109.1093-1-cp0613@linux.alibaba.com>

The riscv64 JIT now supports the gotox instruction and jump tables, so
run the tests in verifier_gotox.c on riscv64 too, mirroring what was done
for arm64 and powerpc.

The guard is 64-bit only because the RV32 JIT does not implement gotox.
