Subject: [PATCH v3 06/16] tcg/mips: Unify TCG_GUEST_BASE_REG tests
Date: Wed, 18 Aug 2021 10:19:21 -1000 [thread overview]
Message-ID: <20210818201931.393394-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210818201931.393394-1-richard.henderson@linaro.org>
In tcg_out_qemu_ld/st, we already check for guest_base matching int16_t.
Mirror that when setting up TCG_GUEST_BASE_REG in the prologue.
