History

Ken Raeburn d24928c05b * elfcode.h (elf_build_phdrs): Unused function deleted. (bfd_shdr_from_section): Ditto. (write_relocs): Don't change section contents for addend. (elf_locate_sh): Return type is now always elf_internal_shdr, since the other types were really aliases for this type anyways. Don't compile this function, since it is static and doesn't appear to be used in this file. (sym_is_global): Return non-zero for weak symbols. Abort if sec ptr is null. (swap_out_syms): Reorder tests so function symbols can be weak. (elf_slurp_symbol_table): Don't use BSF_EXPORT. (elf_slurp_reloca_table): Make RELOC_PROCESSING section smaller by extracting out some common code. Abort if BFD section symbol has null name. (elf_slurp_reloc_table): Translate ELF section symbols into BFD section symbols. Don't read section contents to fill in addend field. * Merged from OSF: Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org) * libelf.h (struct Elf_Sym_Extra): New structure to contain ELF specific information for a symbol. Put in elf_sym_num, which gives the external symbol number in the elf object file, since local symbols must come before global symbols. (elf_sym_extra): New macro. (elf_symtab_map): Delete, in favor of using Elf_Sym_Extra. * elfcode.h (elf_map_symbols): Use Elf_Sym_Extra to map internal symbol number to external number. Store the address of the Elf_Sym_Extra field for the symbol in the udata field. (elf_write_object_contents): Use Elf_Sym_Extra to map out symbols. Sun Jun 20 16:30:11 1993 Michael Meissner (meissner@osf.org) * elfcode.h (elf_obj_tdata): Add field to count the size of the array of pointers to section symbols. (elf_map_symbols): Bump the max index of the section symbols so that we don't overwrite memory. Store the max index into the elf_obj_tdata field. Sat Jun 19 10:12:27 1993 Michael Meissner (meissner@osf.org) * elfcode.h (elf_obj_tdata): Add pointer to an array of pointers to the section symbols we created. Remove unused field internal_syms. (elf_map_symbols): Fill in array of pointers to section symbols. Only create section symbols for sections that have SEC_ALLOC set, and have non-zero size. (elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol, look up the section in the list of section symbols, and set the udata pointer appropriately. Otherwise, if udata is still NULL, fail an assertion, and use 0, instead of dropping core.		33 years ago

README.hppaelf

HPPA/ELF README file:

	HP PA-RISC support was contributed by the Center for Software Science
	at the University of Utah.

This is the status of the hppa/elf code in bfd 2.0 as of January 29, 1993:

1. It generates correct ELF files for all of the input I've given it
so far.  I've used this version of libbfd.a to build an hppa/elf
version of gas 1.36 (emits SOM).  I've run files as large as 200K
lines of assembly through it.

2. ELF executables that are created *always* have 3 program header
table entries.  This is due to the exec() support we have in the
kernel for ELF executables.  It expects *exactly* 3 program header
table entries -- one for text, one for data, and one for bss.
Currently, there's no support for any other types of program header
table entries.
