+
+ * targets.c (target_vector): Re-enable generic ELF and NLM targets.
+
+
+ * elfcode.h (assign_file_position_for_section): Align sh_offset to

+ * targets.c (target_vector): Enable elf32-hppa vector.
+
+ * elf32-hppa.c (hppa_elf_get_section_contents): Add new comments

+Tue Oct 26 02:40:46 1993 Stu Grossman (grossman at cygnus.com)
+
+ * som.c (hppa_object_setup): Set SEC_CODE for .text section so
+ that GDB can figure out text_start and text_end.
+

+
+ 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.
