Browse Source 
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.
