1325 in asymbol udata field.
1327 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1329 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
1330 reloc, used in embedded PIC code.

1338 link_order loop. Use _bfd_generic_link_add_symbols_collect for
1339 add_symbls entry point.
1341 * linker.c (_bfd_generic_final_link): Set reloc_count to 0 before
1342 counting relocs. Set SEC_RELOC flag for any section which has

1347 * linker.c (_bfd_generic_link_add_symbols): Just call
1348 generic_link_add_symbols.
1349 (_bfd_generic_link_add_symbols_collect): New function, like
1350 _bfd_generic_link_add_symbols but also collect constructors and
1351 destructors by name as collect2 does.
1352 (generic_link_add_symbols): New function, like old
1353 _bfd_generic_link_add_symbols but with collect argument.
1354 (generic_link_add_object_symbols): Take collect argument.

1366 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
1367 for first character in an extended name.
1368 (_bfd_write_archive_contents): If ar_padchar == '/', then use
1369 "//" as the name of the special archive member holding the
1370 extended name table.
1372 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1374 Support for link_order types which generate relocs in order to
1375 support -Ur in the linker.
1376 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
1377 from call to _bfd_generic_link_add_one_symbol.
1378 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
1379 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
1380 instead of bitsize to add_to_set call back.
1381 (_bfd_generic_final_link): Account for link_order relocs when
1382 allocating space for relocations. Handle them in link_order loop.
1383 (_bfd_generic_reloc_link_order): New function.
1384 (_bfd_default_link_order): If a reloc_link_order is seen here,
1386 (_bfd_count_link_order_relocs): New function.
1387 * libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
1388 argument from declaration.
1389 (_bfd_generic_reloc_link_order): Declare.
1390 (_bfd_count_link_order_relocs): Declare.

1392 * aoutx.h (aout_link_add_symbols): Remove bitsize argument from
1393 call to _bfd_generic_link_add_one_symbol.

1399 call to _bfd_generic_link_add_one_symbol.
1400 (ecoff_bfd_final_link): Account for link_order relocs when
1401 allocating space for relocations. Handle them in link_order loop.
1402 (ecoff_link_write_external): Set the storage class of a defined
1403 linker created symbol based on the section it is in. Correct
1404 bfd_link_hash_weak case to use .sc rather than .st.
1405 (ecoff_reloc_link_order): New function.
1406 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
1408 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

1413 * cisco-core.c (cisco_core_file_p): Only pass one argument to
1414 bfd_zmalloc. Free a pointer, not a union.
1415 (cisco_bfd_is_local_label): Correct cast from asection to asymbol.
1417 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1419 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
1421 * som.c (bfd_section_from_som_symbol): Only to do the value
1422 comparison for function symbols within executables.
1424 * som.c (bfd_section_from_som_symbol): Renamed from
1425 som_section_from_subspace_index. Pass in a native SOM symbol.
1426 For executables, iterate through the sections to find out
1427 which contains the symbol's address rather than using the
1428 symbol_info field. (symbol_info has a different meaning for
1429 dynamicly linked executables.)
1431 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
1434 * som.c (som_begin_writing): Fix braino (one call to align
1435 space/subspace data was done unconditionally rather than
1436 just for executables.)
1438 * som.c (som_begin_writing): Align text in all executables to
1439 make HPUX kernel happy. Fixes strip/objcopy for shared
1442 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1444 * som.c (som_begin_writing): Account for alignment needs of
1445 subspaces too when writing executables. Never request a negative
1446 bss size. Fixes some problems with demand paged executables,
1447 still having problems with pure executables and shared executables.
1449 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1451 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
1452 bfd_zalloc for rawptr, because later on we may call free, not
1455 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
1456 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
1457 * cisco-core.c: New file.
1458 * Makefile.in: Change accordingly.
1459 * configure.in: Recognize cisco_core_vec.
1460 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
1461 * targets.c: Add cisco_core_vec.
1462 * bfd-in2.h: Rebuilt.
1464 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1466 * som.h (som_copyable_section_data_struct): New structure
1467 containing all the private section information which needs
1468 to be copied from input section to output section during
1470 (som_section_data_struct): Remove several fields now in
1471 som_copyable_section_data_struct. Make the space and
1472 subspace dictionaries be pointers (to save space when
1473 only reading objects).
1475 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
1476 some references changed. Allocate a copyable data stucture if
1477 none exists. Store info into the copyable data structure.
1478 (bfd_som_set_subsection_attributes): Likewise.
1479 (som_is_space, som_is_subspace, som_is_container): New functions.
1480 Use these instead of directly accessing private data.
1481 (som_prep_headers): Allocate space and subspace headers here.
1482 Fill in some fields in the space/subspace headers from the
1484 (som_bfd_copy_private_section_data): Only copy the stuff
1485 that we really need to make objcopy and strip work. Allocate
1486 the copy_data structure for the output bfd before copying.
1488 * som.h (struct som_exec_data): New structure to hold exec
1489 info that must be preserved when running objcopy/strip.
1490 (struct somdata): Add new "exec_data" field and accessor
1491 macro. Add some comments on how the various fields are used.
1492 (som_section_data_struct): Make is_space and is_subspace bitfields.
1493 Delete unused subspace_index. All references now use the
1494 target_index field within the section structure itself.
1496 * som.c (make_unique_section): Delete unused declaration.
1497 (som_bfd_copy_private_bfd_data): New function.
1498 (som_object_setup): Allocate space for and save exec information
1499 that needs to be copied during objcopy/strip.
1500 (som_mkobject): Do not allocate space for a file header here.
1501 It is not used when only reading SOM objects.
1502 (som_prep_headers): Allocate space for and attach a file header
1503 to the output bfd. For executables, use the saved system_id
1504 value rather than trying to guess the right value. Do not abort
1505 wwhen setting file_hdr->entry* for executables.
1506 (som_begin_writing): For executables, set the exec_entry and
1508 (som_copy_private_backend_section_data): Always return a value.
1510 * libhppa.h (PA_PAGESIZE): Define.
1512 * som.c (SOM_ALIGN): Define.
1513 (som_begin_writing): If writing an executable, initialize all
1514 fields in the exec header to zero. Update fields in the exec
1515 header as sizes of loadable subspaces are computed. Carefully
1516 preserve alignments when building executables. Actually write the
1517 exec after all the fields are filled in.
1519 * Better long-filename handling. Reads SOM ABI compliant extended
1520 names, but doesn't quite write compliant extended names yet.
1521 * som.c (som_slurp_extended_name_table): Delete function. The
1522 generic code will handle things correctly.
1523 (som_slurp_armap): Seek to the beginning of the next member.
1524 (normalize): New function.
1525 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
1526 name table into account when computing the file offsets in the
1527 SOM dictionary. Make sure to align to an even boundary.
1528 (som_write_armap): Initialize the checksum to zero.
1529 (ar_maxchars): Fix. Opps.
1531 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1533 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
1534 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
1536 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1538 * bfd-in.h (BFD_VERSION): Use @VERSION@.
1539 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
1540 * bfd-in2.h: Regenerated.
1542 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
1543 this was also named trad_unix_bfd_copy_private_bfd_data.
1545 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1547 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
1548 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
1549 returns NULL, it is not an error. It's possible that some of
1550 these checks are not necessary (because the size can never be
1551 zero), but putting in the checks is the conservative thing to do
1552 in light of the fact that some of these malloc calls replaced
1553 unchecked alloca calls, in which a zero argument would work fine.
1555 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1557 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
1558 duplicate definition.
1559 (osf_core_bfd_is_local_label): Define.
1561 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
1562 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
1563 failure indication, it merely means there are no relocs.
1565 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
1566 after NAME, since SunOS /bin/cc can't handle it.
1568 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
1570 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
1571 From sukes@glue.umd.edu (Tasuki Hirata).
1573 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1575 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
1576 all that convoluted stuff with NAME, CAT3, etc. The convoluted
1577 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
1579 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1581 * som.c (som_prep_for_fixups): Detect section symbols based
1582 on either the lack of private data or the symbol flags. Do not
1583 munge section symbol names anymore -- they no longer confuse GDB.
1584 (som_begin_writing): Leave space for an exec header if writing
1586 (som_slurp_symbol_table): Recognize both forms of section symbol
1587 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
1588 section symbols to be the name of the section they represent.
1589 Debugging symbols begin with "L$0\001", not just "L$".
1591 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1593 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
1595 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
1596 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
1597 and bfd_is_local_label.
1599 * targets.c: Add new entries to the bfd_target structure.
1601 * bfd.c (bfd_copy_private_bfd_data): New definition.
1603 * section.c (bfd_copy_private_section_data): New definition.
1605 * syms.c (bfd_is_local_label): New definition.

1609 * libbfd.c (bfd_generic_is_local_label): New function.
1611 * *-core.c: Provide default definitions for new functions in
1612 the target vector which all point to bfd_false.
1614 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
1615 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
1616 Default new vectors for copying private backend data to bfd_true.
1617 Default new vector for determining if a symbol is a local label
1618 to bfd_generic_is_local_label.
1620 * som.c (som_bfd_copy_private_section_data): New function.
1621 (som_bfd_is_local_label): New function.
1622 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
1624 * elf32-hppa.c (hppa_elf_is_local_label): New function.
1626 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1628 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
1630 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
1633 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
1634 Indent some of them to GNU standards.
1636 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
1637 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
1638 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
1639 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
1640 Update copyright years.
1642 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1644 * som.c (som_prep_for_fixups): A relocation involving the section
1645 symbol for the *ABS* section is really a relocation involving
1647 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
1648 undefined symbols. Correctly distinguish between debugger symbols
1649 and section symbols.
1651 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
1652 for spaces and subspaces.
1654 * som.c (som_bfd_count_ar_symbols): Fix typo.
1656 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
1657 HAS_RELOC based on the object's magic number.
1658 (make_unique_section): Delete function. BFD and its users are
1659 prepared to handle multiple sections with the same name.
1660 (setup_sections): Allocate space on the BFD's obstack to hold
1661 section names. Use bfd_make_setion_anyway rather than the
1662 obsolete make_unique_section.
1663 (som_prep_headers): Choose the correct SOM magic number based
1665 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
1667 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
1669 * elf32-ppc.c: Renamed from elf32-powerpc.c.

1679 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
1680 is always located at the start of the data section to allow
1681 recovery of the dynamic info from a stripped executable.
1682 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
1685 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1687 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
1688 cruft (like the #pragma alloca for AIX).
1689 In addition to that problem, the C alloca calls xmalloc, which
1690 means checking for being out of memory can't work right. The
1691 following changes remove all uses of alloca from BFD.
1692 * hosts/solaris2.h: Remove alloca cruft.
1693 * som.c: Replace alloca with a fixed size auto array.

1699 * libbfd.h: Rebuilt.
1701 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
1703 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
1706 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1708 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
1709 Elf*_Off typedefs by their expansion, the typedefs have been
1710 removed from include/elf/internal.h.
1711 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
1712 SHT_PROGBITS section.
1714 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1716 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

1720 * configure.host: Recognize i[34]86-sequent-*.
1722 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
1723 return from bfd_seek indicates an error.
1724 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
1725 TRAD_CORE_STACK_OFFSET.
1726 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
1727 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
1729 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1731 * som.[ch]: Do not include libhppa.h in som.c, instead include
1734 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
1735 include it in elf32-hppa.h.
1737 * som.c (log2): Return -1 on error rather than aborting.
1738 (setup_sections): Bubble up an error from log2.
1740 * Changes to make HP C compiler happy in both traditional
1742 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
1744 (bfd_som_set_section_attributes): Use unsigned int rather than
1745 unsigned char to avoid GNU-C extensions.
1746 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
1747 or failure rather than aborting on failure.
1749 * som.h (bfd_som_set_section_attributes): Fix prototype to match
1751 (bfd_som_attach_aux_hdr): Add prototype.
1752 (hppa_som-gen_reloc_type): Likewise.
1754 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
1755 (hppa_look_for_stubs_in_section): Do not return false on failure
1756 until rest of code is ready to handle it. Abort for now.
1758 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)

1866 COMPLEX relocation support (it's never used anyway).
1867 (hppa_elf_rebuild_insn): Delete. Moved into libhppa.h.
1868 (elf_hppa_tc_symbol): Accept and use new arguments (symext chains).
1869 (elf_hppa_tc_make_sections): Likewise.

2041 (b_out_relax_section): If a section contains no relocations, don't
2042 bother processing them.
2043 (b_out_get_relocated_section_contents): Set reloc_done. Assert

2746 The sparc (and possibly other?) NLM format requires a different
2747 way to write exports, so add a write_export field to the backend
2748 data (and set it to NULL for everything but the sparc).
