Subject: [PULL 34/37] tcg/riscv: Use tcg_pcrel_diff in tcg_out_ldst
Date: Fri, 20 Jan 2023 17:39:10 +1000 [thread overview]
Message-ID: <20230120073913.1028407-35-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20230120073913.1028407-1-alistair.francis@opensource.wdc.com>
From: Richard Henderson <richard.henderson@linaro.org>
We failed to update this with the w^x split, so misses the fact
that true pc-relative offsets are usually small.
