1994-04-06 * targets.c (bfd_target): Rearranged fields in target vector.Ian Lance Taylor1-15/+35
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.

1991-05-02Merge devo/bfd with GDB's bfd.John Gilmore1-0/+2
Remove obstack.h to ../include and obstack.c to ../libiberty. Move COFF symbol swapping code to coffswap.c where GDB can call it but it won't be duplicated if we have N different COFF targets. Add support for traditional Unix core files (with a upage). This support is from an Ultrix port, but is probably slightly broken now. Improve bfd_release's of obstack'd items on error returns. gcc -Wall fixes. Handle section alignment slightly better in coff, and comment where it needs more work (on page-aligning virtual vs file addresses for DPAGED). Use set_tdata everywhere that tdata is set, to avoid "cast to the left of assignment" problems with some compilers. Move bfd_alloc, bfd_zalloc, bfd_realloc, and bfd_release into libbfd.h (from bfd.h) since they are internal routines. Remove the redundant suffix "_struct" from struct tags. Set symbol count early in file reading, before slurping in the syms, for GDB's use.
