Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com) * bfd-in.h (BFD_VERSION): Use @VERSION@. * Makefile.in (bfd.h): Replace it with contents of VERSION file. * bfd-in2.h: Regenerated. * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where this was also named trad_unix_bfd_copy_private_bfd_data. Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com) * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0) returns NULL, it is not an error. It's possible that some of these checks are not necessary (because the size can never be zero), but putting in the checks is the conservative thing to do in light of the fact that some of these malloc calls replaced unchecked alloca calls, in which a zero argument would work fine. Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com) * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove duplicate definition. (osf_core_bfd_is_local_label): Define. * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a failure indication, it merely means there are no relocs. * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space after NAME, since SunOS /bin/cc can't handle it. Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com) * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field. From sukes@glue.umd.edu (Tasuki Hirata). Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com) * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than all that convoluted stuff with NAME, CAT3, etc. The convoluted stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess). Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu) * som.c (som_prep_for_fixups): Detect section symbols based on either the lack of private data or the symbol flags. Do not munge section symbol names anymore -- they no longer confuse GDB. (som_begin_writing): Leave space for an exec header if writing an executable. (som_slurp_symbol_table): Recognize both forms of section symbol names "L$0\002" and "$$". Change the name of "L$0\002" section symbols to be the name of the section they represent. Debugging symbols begin with "L$0\001", not just "L$". Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu) * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt. * bfd-in.h (JUMP_TABLE): Add new entries to the jump table for bfd_copy_private_section_data, bfd_copy_private_bfd_data, and bfd_is_local_label. * targets.c: Add new entries to the bfd_target structure. * bfd.c (bfd_copy_private_bfd_data): New definition. * section.c (bfd_copy_private_section_data): New definition. * syms.c (bfd_is_local_label): New definition. * libbfd-in.h (bfd_generic_is_local_label): Declare. * libbfd.c (bfd_generic_is_local_label): New function. * *-core.c: Provide default definitions for new functions in the target vector which all point to bfd_false. * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c Default new vectors for copying private backend data to bfd_true. Default new vector for determining if a symbol is a local label to bfd_generic_is_local_label. * som.c (som_bfd_copy_private_section_data): New function. (som_bfd_is_local_label): New function. (som_bfd_copy_private_bfd_data): For now default to bfd_true. * elf32-hppa.c (hppa_elf_is_local_label): New function.

Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu) * som.c (som_prep_for_fixups): A relocation involving the section symbol for the *ABS* section is really a relocation involving no symbol. (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for undefined symbols. Correctly distinguish between debugger symbols and section symbols. * som (setup_sections): Set SEC_DEBUGGING and the section attributes for spaces and subspaces. * som.c (som_bfd_count_ar_symbols): Fix typo. * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and HAS_RELOC based on the object's magic number. (make_unique_section): Delete function. BFD and its users are prepared to handle multiple sections with the same name. (setup_sections): Allocate space on the BFD's obstack to hold section names. Use bfd_make_setion_anyway rather than the obsolete make_unique_section. (som_prep_headers): Choose the correct SOM magic number based on the BFD's flags.

Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com) * libbfd-in.h: Remove alloca cruft. It was missing some necessary cruft (like the #pragma alloca for AIX). In addition to that problem, the C alloca calls xmalloc, which means checking for being out of memory can't work right. The following changes remove all uses of alloca from BFD. * hosts/solaris2.h: Remove alloca cruft. * som.c: Replace alloca with a fixed size auto array. * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c, ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c, sunos.c: Replace alloca with malloc and appropriate error checking and freeing. * linker.c: Replace alloca with obstack_alloc. * libbfd.h: Rebuilt.

(bfd_som_attach_aux_hdr): Add prototype. (hppa_som-gen_reloc_type): Likewise. * elf32-hppa.c: Add a couple casts to make HP compiler happy. (hppa_look_for_stubs_in_section): Do not return false on failure until rest of code is ready to handle it. Abort for now. Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com) * bfd-in2.h: Rebuilt.
