* tramp-frame.h (struct tramp_frame): Change "insn" to a struct containing both bytes and mask. Add "frame_type". * tramp-frame.c (tramp_frame_start): Update. (tramp_frame_prepend_unwinder): Update. * mips-linux-tdep.c (mips_linux_o32_sigframe) (mips_linux_o32_rt_sigframe, mips_linux_n32_rt_sigframe) (mips_linux_n64_rt_sigframe): Update. Make "static const". * ppcnbsd-tdep.c (tramp_frame ppcnbsd_sigtramp): Update.
