|
||||
|
||||
* 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.
