1998-08-09 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/powerpc/Makefile [subdir=elf]: Add new files split out of dl-machine.h. * sysdeps/powerpc/dl-machine.c: New file. * sysdeps/powerpc/dl-machine.h: Move much stuff into separate files. Revise ELF_PREFERRED_ADDRESS to take account of the new mapping information (fixes bug involving huge bloated web browser). Set ELF_MACHINE_PLTREL_OVERLAP. * sysdeps/powerpc/dl-start.S: New file. * elf/dl-load.c (_dl_map_object_from_fd): Initialise l_map_start, l_map_end. * elf/do-rel.h: Call elf_machine_rel only once (to save space). * elf/dynamic-link.h: Allow PLT relocs to be in the middle of the others. Call elf_dynamic_do_##reloc only once (to save even more space). * elf/link.h: Add new members l_map_start and l_map_end to keep track of the memory map. * elf/rtld.c (_dl_start): Initialise l_map_start for ld.so and the executable. 1998-09-01 11:53 Ulrich Drepper <drepper@cygnus.com> * debug/Makefile (catchsegv): We need not rewrite SOVER anymore. Reported by Andreas Jaeger. * posix/glob.h: Use __size_t instead of size_t in definitions and make sure this is defined. * manual/locale.texi: Almost complete rewrite. Document more functions
