1997-09-27 01:14 Ulrich Drepper <drepper@cygnus.com> * Makeconfig (extra-objs): Depend in before-compile. * configure.in: Locate Perl and substitute with complete path. * config.make.in: Add PERL for substitution. * elf/Makefile (routines): Add dl-addr. * elf/dladdr.c: Move the real code into ... * elf/dl-addr.c: New file. * elf/link.h: Add prototype for _dl_addr. * elf/dladdr.c (dladdr): Change address argument to be const. * elf/dlfcn.h: Likewise. * locale/C_name.c: Add _nl_POSIX_name. * locale/localeinfo.h: Add declaration of _nl_POSIX_name. * locale/findlocale.c (_nl_find_locale): Use _nl_POSIX_name. (_nl_remove_locale): Free name of data set. * locale/setlocale.c (clever_copy): Remove. (new_composite_name): Use _nl_C_name and _nl_POSIX_name in compare. (setname): Only remove old name when it is for category LC_ALL. Change malloc, free, realloc, and memalign hooks for glibc to take another parameter indicating the location of the caller. * malloc/malloc.c: Change hook functions and variables. * malloc/malloc.h: Likewise. * malloc/mcheck.c: Likewise. Make sure later hooked function also get the original caller address. * malloc/mtrace.c: Likewise. (tr_where): If no information in _mtrace_file is given use the information about the caller. * malloc/Makefile (distribute): Replace mtrace.awk by mtrace.pl. Add rules to install mtrace.pl after rewriting. * malloc/mtrace.pl: New file. Based on the old AWK script but with extended functionality. * malloc/mtrace.awk: Removed. * po/fr.po: New version. * string/Makefile: Do use builtins for tester.c and inl-tester.c. * string/tester.c: Rewrite. Split in many small functions to not exceed gcc's limits. * sysdeps/unix/sysv/linux/syscalls.list: Add prctl. 1997-09-25 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * string/bits/string2.h (__stpcpy_small): Don't use casts as lvalues. 1997-09-26 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/time.texi (Formatting Date and Time): Clarify explanation of strftime flags a bit. Suggested by Robert Bihlmeyer <robbe@orcus.priv.at>. 1997-09-25 00:13 David S. Miller <davem@tanya.rutgers.edu> * sysdeps/libm-ieee754/s_exp2f.c: Protect _GNU_SOURCE definition. Fix typo, it is FLT_MANT_DIG. 1997-09-24 18:52 H.J. Lu <hjl@gnu.ai.mit.edu> * math/atest-exp2.c: Include <stdlib/gmp.h> instead of <gmp.h>. 1997-08-27 08:10 H.J. Lu <hjl@gnu.ai.mit.edu> * libio/libio.h, libio/libioP.h: Support libio in libstdc++. * libio/libio.h (_IO_peekc): Defined as _IO_peekc_unlocked if _IO_MTSAFE_IO is undefined. 1997-09-24 23:27 Richard Henderson <rth@cygnus.com> * elf/dl-runtime.c (fixup): Don't go through elf_machine_relplt, but lookup the value of the target symbol ourselves and call the new elf_machine_fixup_plt. This kills the ELF_FIXUP_RETURN_VALUE hack. (profile_fixup): Likewise, but don't fix up the plt. * elf/rtld.c (_dl_main): ELF_MACHINE_RELOC_NOPLT renamed _JMP_SLOT. * sysdeps/alpha/dl-machine.h (ELF_MACHINE_RELOC_NOPLT): Renamed. (elf_alpha_fix_plt): Renamed elf_machine_fixup_plt. * sysdeps/i386/dl-machine.h (elf_machine_relplt): Killed. (ELF_MACHINE_JMP_SLOT): Renamed. (elf_machine_fixup_plt): New function. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/powerpc/dl-machine.h: Likewise. (elf_machine_rela): Moved JMP_SLOT fixup out to elf_machine_fixup_plt. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise. * sysdeps/stub/dl-machine.h: Update, sorta. * sysdeps/alpha/dl-machine.h (elf_machine_runtime_setup): Do profiling. (TRAMPOLINE_TEMPLATE): From the carcas of _RUNTIME_TRAMPOLINE, do both normal and profile code. (elf_machine_rela): Handle r_addend for .got and .plt too.
