Subject: [PATCH 32/42] tcg/loongarch64: Simplify constraints on qemu_ld/st
Date: Fri, 7 Apr 2023 19:43:04 -0700 [thread overview]
Message-ID: <20230408024314.3357414-34-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230408024314.3357414-1-richard.henderson@linaro.org>
The softmmu tlb uses TCG_REG_TMP[0-2], not any of the normally available
registers. Now that we handle overlap betwen inputs and helper arguments,
we can allow any allocatable reg.
