* linux-user/nios2 linux-user/riscv: Clean up header guardsMarkus Armbruster2019-05-131-3/+3
| | | | | | | | | | | | | | Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. scripts/clean-header-guards.pl can't tell, so it warns. Since we can avoid guard symbol reuse easily, do so: use guard symbol ${target^^}_${fname^^} for linux-user/$target/$fname, just like we did in commit a9c94277f0..3500385697.

* linux-user: define TARGET_ARCH_HAS_SETUP_FRAMELaurent Vivier2018-04-301-4/+0Star
| | | | | | | | | | | | | 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. Move declarations of setup_frame() and setup_rt_frame() to linux-user/signal-common.h Signed-off-by: Laurent Vivier <laurent@vivier.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20180424192635.6027-21-laurent@vivier.eu>
