2001-12-11 Jakub Jelinek <jakub@redhat.com> * elf/Makefile (dl-routines): Add conflict. (rtld-ldscript-in, rtld-ldscript, rtld-parms): Remove. (ld.so): Add _begin local symbol. * elf/elf.h (DT_VALTAGIDX, DT_VALNUM, DT_ADDRTAGIDX, DT_ADDRNUM): Define. * elf/dl-deps.c (_dl_build_local_scope): New. (_dl_map_object_deps): If LD_TRACE_PRELINKING, compute local scopes of all libraries. * elf/do-rel.h (VALIDX): Define. (elf_dynamic_do_rel): If ELF_MACHINE_PLT_REL is defined, don't do lazy binding for RELA. If DT_GNU_PRELINKED, DT_RELACOUNT relocations can be skipped. * elf/dl-conflict.c: New file. * elf/dl-lookup.c (_dl_debug_bindings): New. (_dl_lookup_symbol): Use _dl_debug_bindings. Reference_name is always non-NULL. (_dl_lookup_symbol_skip): Likewise. (_dl_lookup_versioned_symbol): Likewise. (_dl_lookup_versioned_symbol_skip): Likewise. * elf/dl-runtime.c (PLTREL): If ELF_MACHINE_PLT_REL is defined, define to ElfW(Rel). * elf/dynamic-link.h (elf_get_dynamic_info): Record selected dynamic tags in the DT_VALRNGLO..DT_VALRNGHI and DT_ADDRRNGLO..DT_ADDRRNGHI ranges. Don't adjust address dynamic tags if l_addr is 0. * elf/rtld.c (_dl_trace_prelink, _dl_trace_prelink_map): New variables. (_dl_start): Skip ELF_DYNAMIC_RELOCATE if ld.so is prelinked. (VALIDX, ADDRIDX): Define. (_dl_start_final): Initialize _dl_rtld_map's l_map_start and l_map_end. (dl_main): Print library list for LD_TRACE_PRELINKING. If prelinking information can be used, skip relocating libraries and call _dl_resolve_conflicts instead. (process_envvars): Handle LD_TRACE_PRELINKING envvar. * elf/dl-load.c (_dl_map_object): Don't create fake libs if LD_TRACE_PRELINKING. * include/link.h (struct link_map) [l_info]: Add DT_VALNUM + DT_ADDRNUM. * sysdeps/generic/ldsodefs.h (_dl_trace_prelink_map): New declaration. (DL_DEBUG_PRELINK): Define. (_dl_resolve_conflicts): Add prototype. * sysdeps/alpha/dl-machine.h (elf_machine_runtime_setup): Reinitialize .plt for prelinked libraries where prelinking info cannot be used. (elf_machine_rela): If relocating R_ALPHA_JMP_SLOT in .gnu.conflict section, use RESOLVE_CONFLICT_FIND_MAP to find out reloc's link_map. * sysdeps/arm/bits/link.h: New file. * sysdeps/arm/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (ELF_MACHINE_NO_RELA): Only define if RTLD_BOOTSTRAP. (ELF_MACHINE_PLT_REL): Define. (elf_machine_rela, elf_machine_rela_relative): New. (elf_machine_lazy_rel): Reinitialize R_ARM_JUMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. * sysdeps/i386/bits/link.h: New file. * sysdeps/i386/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (ELF_MACHINE_NO_RELA): Only define if RTLD_BOOTSTRAP. (ELF_MACHINE_PLT_REL): Define. (elf_machine_rela, elf_machine_rela_relative): New. (elf_machine_lazy_rel): Reinitialize R_386_JUMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. * sysdeps/powerpc/dl-machine.h (elf_machine_rela): If relocating conflicts, skip finaladdr computation. Use RESOLVE_CONFLICT_FIND_MAP to find out map for R_PPC_JMP_SLOT relocs. * sysdeps/sparc/sparc32/dl-machine.h (VALIDX): Define. (OPCODE_BA): Define. (elf_machine_runtime_setup): Reinitialize .plt for prelinked libraries where prelinking info cannot be used. (sparc_fixup_plt): Renamed from elf_machine_fixup_plt. (elf_machine_fixup_plt): Call sparc_fixup_plt. (elf_machine_rela): Set value to 0 if relocating conflicts. Call sparc_fixup_plt for R_SPARC_JMP_SLOT. * sysdeps/sparc/sparc64/dl-machine.h (VALIDX): Define. (sparc64_fixup_plt): Fix a typo. (elf_machine_rela): Set value to 0 if relocating conflicts. Handle R_SPARC_JMP_SLOT relocs when relocating conflicts. (elf_machine_runtime_setup): Reinitialize .plt for prelinked libraries where prelinking info cannot be used. * sysdeps/sh/bits/link.h: New file. * sysdeps/sh/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (elf_machine_lazy_rel): Reinitialize R_SH_JMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. * sysdeps/s390/s390-32/bits/link.h: New file. * sysdeps/s390/s390-32/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (elf_machine_lazy_rel): Reinitialize R_390_JMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. * sysdeps/s390/s390-64/bits/link.h: New file. * sysdeps/s390/s390-64/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (elf_machine_lazy_rel): Reinitialize R_390_JMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. * sysdeps/x86_64/bits/link.h: New file. * sysdeps/x86_64/dl-machine.h (elf_machine_runtime_setup): Save original content of .got[1]. (elf_machine_lazy_rel): Reinitialize R_X86_64_JMP_SLOT address instead of adjusting it if prelinked and prelinking cannot be used. |
