* sysdeps/mach/hurd/dl-sysdep.c (__open): Define this instead of open. (__close, __mmap): Likewise define with __ names now. Mon Jun 10 05:13:18 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/dl-support.c: New file. * elf/Makefile (CFLAGS-dl-support.c): New variable. (routines, elide-routines.so): Add dl-support. * elf/dl-minimal.c (_dl_pagesize): Remove common defn. * elf/dl-load.c (_dl_pagesize): Define it here. (_dl_map_object_from_fd): Initialize it if zero. * elf/link.h (_dl_pagesize): Remove const. Sun Jun 9 04:04:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/Makefile (routines): Add dl-symbol. * elf/dl-lookup.c (_dl_symbol_value): Moved to ... * elf/dl-symbol.c: New file. * elf/elf.h (Elf32_Xword, Elf32_Sxword): New types. (Elf32_Section, Elf64_Section): New types, 16 bits. (Elf32_Sym, Elf64_Sym): Use it. * elf/dl-deps.c (_dl_open): Moved to ... * elf/dl-open.c: New file. * Makefile (routines): Add dl-open. * elf/Makefile (dl-routines): New variable. (routines): Add $(dl-routines). (elide-routines.so): New variable, set to $(dl-routines). (libdl-inhibit-o): Variable removed; build all flavors of -ldl. (rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to $(dl-routines). * elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage. * elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND. * elf/dl-load.c (open_path): Use __ names for open and close. Avoid using strdup. (_dl_map_object): Likewise. (_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect. * elf/dl-minimal.c (malloc): Likewise. * elf/dl-reloc.c (_dl_relocate_object): Likewise. * elf/dl-minimal.c (_dl_pagesize): New variable. (malloc): Use that instead of a static variable. * elf/dl-reloc.c (_dl_relocate_object): Use _dl_pagesize instead of calling getpagesize. * elf/dl-load.c (_dl_map_object_from_fd): Likewise. * elf/link.h: Declare _dl_pagesize. * elf/rtld.c (dl_r_debug): Renamed to _dl_r_debug. * elf/link.h (struct link_map): Use Half for l_phnum instead of Word. * elf/rtld.c (dl_main): Use Half for phdr count arg. (_dl_sysdep_start): Update prototype of DL_MAIN function ptr arg. * elf/dl-load.c (_dl_map_object_from_fd): Use explicit Elf32_Word to extract 4-byte magic number, not ElfW(Word). Match EI_CLASS against native wordsize, either 32 or 64. * elf/elf.h (Elf64_Byte, Elf64_Section): Typedefs removed. In C a char is always a byte, no need for a typedef. Section indices are 16-bit quantities in elf64, which already have a typedef Elf64_Half. Remove partial -lelf implementation. There is now a separately-distributed `libelf' package that implements it. * elf/dl-lookup.c: Don't #include <libelf.h> any more. (_dl_elf_hash): New function, moved from libelf.h:elf_hash. (_dl_lookup_symbol): Use it instead of elf_hash. * elf/libelf.h: File removed. * elf/elf_hash.c: File removed. * elf/Makefile (headers): Remove libelf.h. (extra-libs): Remove libelf. (libelf-routines): Variable removed. * elf/Makefile (libdl.so): Remove commands from this target. The implicit rule commands are correct, this explicit rule just serves to add some dependencies. * elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of ELF32_ST_TYPE. Likewise ST_BIND. * elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM. * elf/link.h (ElfW): New macro for wordsize-independent ElfXX_* type naming. (ELFW): New macro, likewise for ELFXX_* macro naming. (_ElfW, _ElfW_1): New macros, subroutines of ElfW and ELF. Sat Jun 8 20:52:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/link.h, elf/do-rel.h, elf/dynamic-link.h, elf/dl-deps.c, elf/dl-init.c, elf/dl-load.c, elf/dl-lookup.c, elf/dl-reloc.c, elf/dl-runtime.c, elf/dladdr.c, elf/dlclose.c, elf/dlsym.c, elf/linux-compat.c, elf/rtld.c: Change all uses of `Elf32_XXX' to `ElfW(XXX)' for wordsize-independence. Sat Jun 8 20:50:42 1996 Richard Henderson <rth@tamu.edu> * elf/elf.h: Move Elf64_* types in parity with Elf32 counterparts. (Elf64_auxv_t): New type. (EM_ALPHA, R_ALPHA_*): New macros for elf64-alpha format.
