Subject: [PULL 10/33] tcg/tci: Move call-return regs to end of tcg_target_reg_alloc_order
Date: Sat, 19 Jun 2021 11:14:29 -0700 [thread overview]
Message-ID: <20210619181452.877683-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210619181452.877683-1-richard.henderson@linaro.org>
As the only call-clobbered regs for TCI, these should
receive the least priority.
Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
