Subject: [PATCH 32/89] linux-user/sh4: Create init_main_thread
Date: Tue, 29 Jul 2025 13:59:05 -1000 [thread overview]
Message-ID: <20250730000003.599084-33-richard.henderson@linaro.org> (raw)
In-Reply-To: <20250730000003.599084-1-richard.henderson@linaro.org>
Merge init_thread and target_cpu_copy_regs.
There's no point going through a target_pt_regs intermediate.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
