* dwarf2-frame.c (dwarf2_frame_cache, dwarf2_frame_this_id)
(dwarf2_frame_sniffer): Update. (dwarf2_signal_frame_this_id): New function. (dwarf2_signal_frame_unwind): Use it. (dwarf2_frame_base_sniffer): Use frame_unwind_address_in_block. * frame.c (frame_func_unwind): Add this_type argument. (get_frame_func): Update. (frame_unwind_address_in_block): Add this_type argument and check it. Fix a typo. (get_frame_address_in_block): Update. * frame.h (enum frame_type): Move higher in the file. (frame_unwind_address_in_block, frame_func_unwind): Add enum frame_type argument. * alpha-mdebug-tdep.c, alpha-tdep.c, amd64-tdep.c, amd64obsd-tdep.c, arm-tdep.c, avr-tdep.c, cris-tdep.c, frv-tdep.c, h8300-tdep.c, hppa-tdep.c, i386-tdep.c, i386obsd-tdep.c, ia64-tdep.c, libunwind-frame.c, m32c-tdep.c, m32r-linux-tdep.c, m32r-tdep.c, m68hc11-tdep.c, m68k-tdep.c, m88k-tdep.c, mips-mdebug-tdep.c, mips-tdep.c, mn10300-tdep.c, mt-tdep.c, rs6000-tdep.c, s390-tdep.c, score-tdep.c, sh-tdep.c, sh64-tdep.c, sparc-tdep.c, sparc64obsd-tdep.c, spu-tdep.c, v850-tdep.c, vax-tdep.c, xstormy16-tdep.c, xtensa-tdep.c: Update calls to frame_func_unwind and frame_unwind_address_in_block to specify the frame type. Use frame_unwind_address_in_block instead of frame_pc_unwind in sniffers. * gdb.arch/i386-signal.c, gdb.arch/i386-signal.exp: New files.
