Subject: [PATCH 03/12] tcg/mips: Unify TCG_GUEST_BASE_REG tests
Date: Fri, 7 Apr 2023 20:03:50 -0700 [thread overview]
Message-ID: <20230408030359.3368868-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230408030359.3368868-1-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.
