Ian Lance Taylor	b6eb341bf8	Mon Jun 16 18:56:27 1997 Geoff Keating <geoffk@ozemail.com.au> * elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL* relocs in shared libraries which refer to local symbols. Cope with addend when processing a GOT relocation. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols for sections that the linker didn't create. (ppc_elf_finish_dynamic_sections): Only try to write out a section symbol if it was created in ppc_elf_size_dynamic_sections. (ppc_elf_relocate_section): Complain if we have to generate a reloc relative to a section for which we didn't output a symbol. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up. PLT relocs are 'rela' relocs, like everything else. .rela.plt is not a read-only section, so we don't have to special-case it. * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the .rela.bss section are (of course) 'rela' relocs not 'rel' relocs. * elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot. (ppc_elf_relocate_section): @got offsets are 4 from start of the actual .got section. * elflink.c (_bfd_elf_create_got_section): The three reserved words start from the symbol '_GLOBAL_OFFSET_TABLE_'. * elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5 characters, not 4. * elf32-ppc.c (ppc_elf_check_relocs): Use _bfd_elf_create_got_section to create the GOT rather than ppc_elf_create_linker_section. Create the '.rela.got' section ourselves. (ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a symbol has a GOT entry. (ppc_elf_relocate_section): Record when a symbol is used through the GOT, and allocate space in the GOT for each such symbol. (ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff. (ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT stuff. * elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be treated in a similar way to ADDR16_HA relocs. (ppc_elf_relocate_section): PLTREL24 relocs do not get copied into shared objects; the linker must deal with them. (ppc_elf_create_linker_section): Stop setting _GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused LINKER_SECTION_PLT stuff. (ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff. (ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT section, not ELF-specific calls. (elf_backend_plt_not_loaded): Set to 1. (elf_backend_got_symbol_offset): Set to 4. * elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member for when ld.so fills in the PLT; and 'got_symbol_offset' member. * elflink.c (_bfd_elf_create_dynamic_sections): Apply plt_not_loaded member. (_bfd_elf_create_got_section): Apply got_symbol_offset. * elfxx-target.h (elf_backend_plt_not_loaded): Set default to 'loaded'. (elf_backend_G_O_T_offset): Set default to 0. (elfNN_bed): Set added fields. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting DT_RELENT in shared objects; should be DT_RELAENT. * elf32-ppc.c (ppc_elf_relocate_section): Propagate R_PPC_ADDR16_HA relocs to shared objects. Cope with case where such a reloc (in a non-shared object) refers to a symbol that's not defined.	30 years ago

Ian Lance Taylor	ff12f30335	Fri Jan 3 16:58:31 1997 Richard Henderson <rth@tamu.edu> elf64-alpha multiple .got rewrite: * elf-bfd.h (struct elf_backend_data): Add always_size_sections entry.

Michael Meissner	dd82c578be	Add support -mrelocatable-lib	31 years ago
Ken Raeburn	ede4eed483	Added new files elflink.c, elflink.h, elfcore.h. Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data structure to elfcode.h with some misc data and callback functions. Added a pointer to that structure to the target back end data. More work can be done here. Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or _bfd_elf. Updated most call sites, sometimes defined some macros. Moved some dynamic linking support code from m68k, sparc, i386 to common files, using target back end flags to control behavior. More work can probably be done here too. Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h, elflink.h, or elflink.c. Now elfcode.h contains only .o and executable support, plus #includes of elfcore.h and elflink.h. Much of the contents of these other header files can probably still be moved from the .h files to the .c files, to get compiled only once. Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized variables, in generic and cpu-specific code.	32 years ago
Michael Meissner	bcbe2c719c	Fix powerpc PC relative reloc & add some 16 bit relocs.	32 years ago
