* i386-linux-tdep.c (i386_linux_sigtramp_saved_pc,
i386_linux_sigtramp_saved_sp): Make static. (i386_linux_frame_saved_pc): New function based on the old FRAME_SAVED_PC macro, but use read_memory_unsigned_integer instead of read_memory_integer. * config/i386/tm-linux.h (sigtramp_saved_pc): Remove definition. (i386_linux_sigtramp_saved_pc): Remove prototype. (FRAME_SAVED_PC): Redefine in terms of i386_linux_frame_saved_pc. (i386_linux_frame_saved_pc): New prototype.
