Thu Oct 21 12:16:26 1993 Ken Raeburn (raeburn@cygnus.com)
* elfcode.h (FILE_ALIGN): Renamed from EALIGN, to avoid conflict
with Ultrix header files.
* som.h (struct som_section_data_struct): Renamed from
som_section_data to avoid conflict with macro by that name.
Changes from Jeff Law and Peter Hoogenboom at Utah:
* elf32-hppa.c (hppa_elf_reloc): Target register for a 'jump
in delay slot' optimization in combination with a long call
stub should always be r31.
* elf32-hppa.c: (hppa_elf_relocate_insn): To be consistent
across all relocation types, retrieve instruction addends from
the relocation entry rather than from the instruction itself.
* elf32-hppa.c: (hppa_elf_relocate_insn): Fix a relocation
error that only occurred when the addend of an 'addil' or
'ldil' was larger than 21 bits and very close to a 2K byte
boundary.
* elf32-hppa.c: (hppa_elf_reloc): Handle the optimization in
which a jump is placed in the delay slot of a function call.
The jump was being accomplished via an adjustment to the
return pointer. This optimization would break the long call
stub code, if there was any.
* elf32-hppa.c: (hppa_elf_build_long_branch_stub): Corrections
to long branch stubs to avoid use of general register 2.
* hppa_stubs.h: New stub instructions.
* elfcode.h: Declare bfd_elf_find_section.
* som.h (som_section_data): Add new "subspace_index" field.
* som.c (setup_sections): Save the original SOM subspace index
in the BFD section associated with that subspace.
(som_get_symtab_upper_bound): Implement.
(som_get_symtab): Implement.
(som_print_symbol): Implement.
(som_slurp_string_table): New function to read a string table
from a SOM object file.
(som_section_from_subspace_index): New function to return the
section which corresponds to a SOM subspace index.
(som_slurp_symbol_table): New function to read the symbol
table from a SOM object file.
(som_make_empty_symbol): Check for errors from bfd_zalloc.
(som_new_section_hook): Initialize subspace_index field to
-1 instead of 0.
* som.c (som_object_setup): Fix polarity of test to set HAS_RELOC.
Set EXEC_P for executables.
(setup_sections): Correctly identify when a section has
relocations.
(log2): New function.
(setup_sections): Correctly convert between SOM alignments and BFD
alignments.
* som.c (setup_sections): Do not set SEC_ALLOC or SEC_LOAD
for sections which correspond to SOM spaces, doing so confuses
many utilities. Set assorted SEC_* flags for SOM subspaces
which correspond to BFD sections.
* elf32-hppa.c: (elf32_hppa_backend_fake_sections): The stab
string table should have sh_type == SHT_STRTAB. Add
processing to make it so.
* elfcode.h: (bfd_section_from_shdr): String tables (other
than .strtab) were not getting the file offsets recorded, so
they could not be read from disk.
* elfcode.h: (elf_make_sections): Leave the sh_addr field of
the section header and the vma field of a section at 0 if the
section is not part of the program execution image. (e.g.,
.stab)
* som.[hc]: Change target vector prefix from "hppa" to "som".
Consistently use obj_som prefix to access fields in backend data
structures. Fix all callers/references.
* som.h: Do not include files only needed for core file reading here.
Include a.out for both HOST_HPPAHPUX and HOST_HPPABSD. Delete
forward structure declarations, they are unnecessary.
(struct somdata): Delete aux_hdr, and hp_symbol_entry_size fields.
Change "symbols" to "symtab". Add "stringtab" and "reloc_filepos"
fields for future use. Change obj_som_* macros as appropriate.
(som_section_data): New structure to keep SOM specific information
about BFD sections (for future use).
* som.c: Provide PARAMS declarations for all functions currently
in this file.
(struct container): Delete unwanted structure definition.
(som_object_setup): Add comments. Use som_mkobject to allocate
SOM specific information in the BFD; use information from the
file and (possibly empty) auxiliary headers to initialize this
information. Delete redundant bfd_get_symcount (abfd) "calls".
(setup_sections): Return type is now boolean, fix return statements.
"Fix" handling of BSS like subspaces in the computation of the
containing space's size. If the subspace has relocations, set the
appropriate BFD section flags and record the index into and the
size of the fixup stream. Always return a value.
(som_object_p): Set bfd_error appropriately if errors are detected
from bfd_{read,seek} functions. Handle EXECLIBMAGIC type files.
Do not try to read a non-existant auxiliary header.
(som_mkobject): Flesh out.
(som_section_hook): Allocate space to hold SOM specific information
about sections.
