from call to _bfd_generic_link_add_one_symbol.

Update copyright notices
2001-03-09 05:04:02 +08:00
* som.c (som_begin_writing): Fix thinko (off by one error).
19990502 sourceware import
1999-05-03 15:29:11 +08:00
* som.c (bfd_section_from_som_symbol): Only to do the value
comparison for function symbols within executables.
* som.c (bfd_section_from_som_symbol): Renamed from
som_section_from_subspace_index. Pass in a native SOM symbol.
For executables, iterate through the sections to find out
which contains the symbol's address rather than using the
symbol_info field. (symbol_info has a different meaning for
dynamicly linked executables.)
* trad-core.c (trad_unix_core_file_p): Don't pass abfd to
bfd_zmalloc.
* som.c (som_begin_writing): Fix braino (one call to align
space/subspace data was done unconditionally rather than
just for executables.)
* som.c (som_begin_writing): Align text in all executables to
make HPUX kernel happy. Fixes strip/objcopy for shared
executables.
Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* som.c (som_begin_writing): Account for alignment needs of
subspaces too when writing executables. Never request a negative
bss size. Fixes some problems with demand paged executables,
still having problems with pure executables and shared executables.
Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
bfd_zalloc for rawptr, because later on we may call free, not
bfd_release, on it.
* bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
* libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
* cisco-core.c: New file.

Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* som.h (som_copyable_section_data_struct): New structure
containing all the private section information which needs
to be copied from input section to output section during
objcopy or strip.
(som_section_data_struct): Remove several fields now in
som_copyable_section_data_struct. Make the space and
subspace dictionaries be pointers (to save space when
only reading objects).
* som.c (bfd_som_set_section_attributes): Now returns a boolean;
some references changed. Allocate a copyable data stucture if
none exists. Store info into the copyable data structure.
(bfd_som_set_subsection_attributes): Likewise.
(som_is_space, som_is_subspace, som_is_container): New functions.
Use these instead of directly accessing private data.
(som_prep_headers): Allocate space and subspace headers here.
Fill in some fields in the space/subspace headers from the
copyable data.
(som_bfd_copy_private_section_data): Only copy the stuff
that we really need to make objcopy and strip work. Allocate
the copy_data structure for the output bfd before copying.
* som.h (struct som_exec_data): New structure to hold exec
info that must be preserved when running objcopy/strip.
(struct somdata): Add new "exec_data" field and accessor
macro. Add some comments on how the various fields are used.
(som_section_data_struct): Make is_space and is_subspace bitfields.
Delete unused subspace_index. All references now use the
target_index field within the section structure itself.
* som.c (make_unique_section): Delete unused declaration.
(som_bfd_copy_private_bfd_data): New function.
(som_object_setup): Allocate space for and save exec information
that needs to be copied during objcopy/strip.
(som_mkobject): Do not allocate space for a file header here.
It is not used when only reading SOM objects.
(som_prep_headers): Allocate space for and attach a file header
to the output bfd. For executables, use the saved system_id
value rather than trying to guess the right value. Do not abort
wwhen setting file_hdr->entry* for executables.
(som_begin_writing): For executables, set the exec_entry and
exec_flags fields.
(som_copy_private_backend_section_data): Always return a value.
* libhppa.h (PA_PAGESIZE): Define.
* som.c (SOM_ALIGN): Define.
(som_begin_writing): If writing an executable, initialize all
fields in the exec header to zero. Update fields in the exec
header as sizes of loadable subspaces are computed. Carefully
preserve alignments when building executables. Actually write the
exec after all the fields are filled in.
* Better long-filename handling. Reads SOM ABI compliant extended
names, but doesn't quite write compliant extended names yet.
* som.c (som_slurp_extended_name_table): Delete function. The
generic code will handle things correctly.
(som_slurp_armap): Seek to the beginning of the next member.
(normalize): New function.
(som_bfd_ar_write_symbol_stuff): Take the size of the extended
name table into account when computing the file offsets in the
SOM dictionary. Make sure to align to an even boundary.
(som_write_armap): Initialize the checksum to zero.
(ar_maxchars): Fix. Opps.

machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
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

linker stubs into a single function (so they can easily share a
ton of common code).
Sat Feb 26 10:00:45 1994 Ian Lance Taylor (ian@cygnus.com)
* reloc.c (_bfd_relocate_contents): Adjust handling of overflow to

(only testing for m68k and vax at the moment); do verify that the
preprocessor didn't trash the arch name inside the string version.
Don't print out "pagesize =" line that prevents output from
compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
results.
* Makefile.in (aout-params.h): Pass gen-aout a dummy target name.
(check, installcheck): Identify directory in "no testsuites"
message.

.pdata section based on lnnoptr field, not section header.
(alpha_relocate_section): Don't bother to check if r_symndx >= 0,
