linux-user: Clean up target_signal.h header guards These headers all use TARGET_SIGNAL_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_SIGNAL_H for linux-user/$target/target_signal.h.

linux-user: move generic signal definitions to generic/signal.h No code change. Signed-off-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <20180529194207.31503-10-laurent@vivier.eu> 2018-05-29 21:42:01 +02:00			`#include "../generic/signal.h"`

linux-user: define TARGET_ARCH_HAS_SETUP_FRAME 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> 2018-04-24 21:26:35 +02:00			`#define TARGET_ARCH_HAS_SETUP_FRAME`
linux-user/arm: Implement setup_sigtramp Mirror what the kernel does in arch/arm/kernel/signal.h, using the old sigframe struct in the rt sigframe struct. Update the trampoline code to match the kernel: this uses sp-relative accesses rather than pc-relative. Copy the code into frame->retcode from the trampoline page. This minimises the different cases wrt arm vs thumb vs fdpic.
