Create a cpu_loop-common.h for future use by these new files and use it in the existing main.c Introduce target_cpu_copy_regs(): declare the function in cpu_loop-common.h and an empty function for each target, to move all the cpu_loop prologues to this function.

Instead of calling setup_frame() conditionally to a list of known targets, define TARGET_ARCH_HAS_SETUP_FRAME if the target provides the function and call it only if the macro is defined.

2018-02-25linux-user: Move CPU type name selection to a functionLaurent Vivier1-0/+14
Instead of a sequence of "#if ... #endif" move the selection to a function in linux-user/*/target_elf.h We can't add them in linux-user/*/target_cpu.h because we will need to include "elf.h" to use ELF flags with eflags, and including "elf.h" in "target_cpu.h" introduces some conflicts in elfload.c Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20180220173307.25125-2-laurent@vivier.eu>
