Subject: [PATCH v3 40/70] tcg/tci: Move call-return regs to end of tcg_target_reg_alloc_order
Date: Sun, 7 Feb 2021 18:37:22 -0800 [thread overview]
Message-ID: <20210208023752.270606-41-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210208023752.270606-1-richard.henderson@linaro.org>
As the only call-clobbered regs for TCI, these should
receive the least priority.
