9 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
11 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
12 cruft (like the #pragma alloca for AIX).
13 In addition to that problem, the C alloca calls xmalloc, which
14 means checking for being out of memory can't work right. The
15 following changes remove all uses of alloca from BFD.

135 PARAMize and staticize rest of functions. Delete unused
136 functions. Delete unused/unnecessary arguments to some functions.
137 Group static vars together. Abort for bad errors until we have

236 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

359 link_order size field against cooked size, not raw size, of input
362 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
364 (aligncode): When shrinking, the addend should be set to the
365 current offset in the section plus the number of bytes of padding
366 that will actually be retained.
367 (b_out_relax_section): If a section contains no relocations, don't
368 bother processing them.

453 Make all callers of malloc or realloc (including via obstacks)
454 check the result for NULL. Most set bfd_error to no_memory and
455 return in that case; a few are harder to fix, and are marked

826 bfd_coff_symname_in_debug returns true, don't put symbol name in

852 symbol has a value in the ECOFF symbol but not in the BFD symbol,
853 keep the value in the ECOFF symbol. This helps gas.
855 * linker.c (_bfd_generic_link_output_symbols,
856 _bfd_generic_link_write_global_symbol): Don't require that all
857 references to a common symbol be themselves common symbols.

875 * coff-mips.c (mips_ecoff_backend_data), coff-alpha.c
876 (alpha_ecoff_backend_data): Change casts of aux_in and aux_out

882 coff-m68k.c, coff-sh.c, coff-we32k.c, coff-z8k.c: Changed

892 * libcoff.h: Rebuilt.
893 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
894 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT

897 new arguments to swap_aux functions.
899 Sun Jan 30 15:14:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
901 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
902 (only testing for m68k and vax at the moment); do verify that the

905 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
907 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.
908 (check, installcheck): Identify directory in "no testsuites"

923 * linker.c (generic_link_add_symbol_list): If symbol is common,

934 bfd_som_set_subsection_attributes): Change parameters from char
935 to int. Following a prototype with an old-style function definition
936 in the presence of widened parameters is a GCC-ism not supported

1072 The sparc (and possibly other?) NLM format requires a different
1073 way to write exports, so add a write_export field to the backend
1074 data (and set it to NULL for everything but the sparc).
