Removed _bfd_debug_info_start, _bfd_debug_info_end and _bfd_debug_info_accumulate, which were never used. (BFD_JUMP_TABLE_GENERIC, BFD_JUMP_TABLE_COPY): Defined. (BFD_JUMP_TABLE_CORE, BFD_JUMP_TABLE_ARCHIVE): Defined. (BFD_JUMP_TABLE_SYMBOLS, BFD_JUMP_TABLE_RELOCS): Defined. (BFD_JUMP_TABLE_WRITE, BFD_JUMP_TABLE_LINK): Defined. * All backends: Changed to use the new BFD_JUMP_TABLE_* macros rather than the single JUMP_TABLE macro. Removed many of the weird macro definitions needed to support the monolithic JUMP_TABLE. * bfd-in.h (JUMP_TABLE): Removed. * libbfd-in.h: Define a bunch of macros, and declare a few functions, for use with the new BFD_JUMP_TABLE_* macros. * libbfd.c (_bfd_dummy_new_section_hook): Removed. (bfd_false): Set bfd_error_invalid_operation. (bfd_nullvoidptr): Likewise. (bfd_n1): New function. (_bfd_nocore_core_file_matches_executable_p): Renamed from _bfd_dummy_core_file_matches_executable_p. (_bfd_nocore_core_file_failing_command): Similar rename. Set bfd_error_invalid_operation. (_bfd_nocore_core_file_failing_signal): Likewise. (_bfd_generic_get_section_contents): Renamed from bfd_generic_get_section_contents. Changed all callers. (_bfd_generic_set_section_contents): Similar rename. * ieee.c: #if 0 out ieee_bfd_debug_info_start, ieee_bfd_debug_info_end, ieee_bfd_debug_info_accumulate. They were never called. * bfd-in2.h: Rebuilt. * libbfd.h: Rebuilt.
