* aout-target.h, aoutf1.h, trad-core.c, coffcode.h, libaout.h: Eliminate all PROTO calls, replace with PARAMS for readability. * aoutx.h: Add type to callback parameter. * coff-mips.c: Don't call trad-core.h, not needed. * trad-core.c: Incorporate trad-core.h declarations. Fix comments. * trad-core.h: Eliminate, unused.

* coff-mips.c (ecoff_mkobject_hook): Mark ZMAGIC files as D_PAGED. (ecoff_write_object_contents): If not D_PAGED, don't add the section headers to text_size. If not D_PAGED, set the magic number to OMAGIC rather than ZMAGIC. If creating a D_PAGED executable, the executable must fully occupy an even number of pages. (ecoff_set_symbol_info, make_bfd_asection, ecoff_little_vec, ecoff_big_vec): Consistently set section alignment power to 4, since ECOFF sections should be multiples of 16 bytes. (ecoff_little_vec, ecoff_big_vec): Added D_PAGED to object_flags. Made ar_pad_char and ar_max_namelen agree for both.

* coff-mips.c (ecoff_mkobject_hook): Mark ZMAGIC files as D_PAGED. (ecoff_write_object_contents): If not D_PAGED, don't add the section headers to text_size. If not D_PAGED, set the magic number to OMAGIC rather than ZMAGIC. If creating a D_PAGED executable, the executable must fully occupy an even number of pages. (ecoff_set_symbol_info, make_bfd_asection, ecoff_little_vec, ecoff_big_vec): Consistently set section alignment power to 4, since ECOFF sections should be multiples of 16 bytes. (ecoff_little_vec, ecoff_big_vec): Added D_PAGED to object_flags. Made ar_pad_char and ar_max_namelen agree for both.

Some of these are guesses, if you know different, just yell. Thu Oct 8 08:52:48 1992 Steve Chamberlain (sac@thepub.cygnus.com) Now a bfd knows whether underscores are normally prepended to symbols in its file format. Helps with error messages. * aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c, coff-z8k.c: targets set so they have leading underscore * coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c, coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set without leading underscore flag * targets.c: add symbol leading char to xvec description * bfd-in.h (bfd_get_symbol_leading_char): new macro.
