Subject: [PATCH bpf-next v3 3/4] selftests/bpf: Enable gotox liveness test for riscv64
Date: Mon, 28 Sep 2026 15:18:44 +0800	[thread overview]
Message-ID: <20260928071845.2432-4-cp0613@linux.alibaba.com> (raw)
In-Reply-To: <20260928071845.2432-1-cp0613@linux.alibaba.com>

The riscv64 JIT now supports gotox, so enable the gotox liveness test in
compute_live_registers.c on riscv64 as well.

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