1997-09-25 00:23 Ulrich Drepper <drepper@cygnus.com> * elf/dl-profile.c: Correct implementation. * io/ftwtest-sh: Don't depend on TMPDIR == /tmp. * locale/setlocale.c: Rewrite a bit for more clarity. * math/Makefile (libm-calls): Add w_exp2. * math/math_private.h: Add prototypes for __ieee754_exp2{,f,l}. * sysdeps/libm-i387/s_exp2.S: Change name to __ieee754_exp2. * sysdeps/libm-i387/s_exp2f.S: Likewise. * sysdeps/libm-i387/s_exp2l.S: Likewise. * sysdeps/libm-ieee754/k_standard.c: Add error cases for exp2. * string/bits/string2.h (__strcpy_small): Optimize. (__stpcpy_small): Likewise. (strncpy): Use variable for dest argument since it's used more than once. (strncat): Likewise. (strcmp): Add optimization for this function. * sysdeps/i386/i486/string.h (strlen): Correctly use __builtin_strlen. (__strcpy_small): Optimize. (__stpcpy_small): Likewise. (__stpcpy_c): Correctly use __mempcpy_* macros. (__mempcpy_by2, __mempcpy_by4, __mempcpy_byn): Return pointer to byte following last copied. (strncat): Use variable for dest argument since it's used more than once. (strcmp): Add optimization for this function. * sysdeps/i386/dl-machine.h (ELF_MACHINE_RUNTIME_TRAMPOLINE): Use .text and .previous to select correct section. 1997-09-23 19:56 Philip Blundell <Philip.Blundell@pobox.com> * configure.in: Add `--disable-versioning' option to suppress the use of symbol versions even if binutils claims to support it. 1997-09-24 20:10 Philip Blundell <Philip.Blundell@pobox.com> * csu/Makefile (before-compile): Don't try to build abi-tags.h if not using ELF. 1997-09-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/sofini.c [HAVE_DWARF2_UNWIND_INFO]: Supply termination for the frame unwind info section. * elf/soinit.c [HAVE_DWARF2_UNWIND_INFO]: Register and unregister the frame unwind info. * config.h.in (HAVE_DWARF2_UNWIND_INFO): Add #undef. * configure.in: Check whether gcc supports DWARF2 unwind info. * libc.map: Export frame handling tables. 1997-09-10 06:56 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/unix/sysv/linux/powerpc/bits/kernel_termios.h: Use the size of the kernel's termios structure for ioctls. * sysdeps/powerpc/dl-machine.h: Prepare for library profiling. * sysdeps/powerpc/bits/mathinline.h: Add slightly slower versions of the C9X FP comparison macros. Delete 'fabs' and 'sqrt' inline routines, because gcc has them as internals. * sysdeps/powerpc/Makefile (pic-ccflags): Define this instead of CFLAGS-.os. * sysdeps/powerpc/bzero.S: New file. * sysdeps/powerpc/strcat.c: New file. * sysdeps/powerpc/strcpy.S: New file. * sysdeps/powerpc/stpcpy.S: New file. * math/Makefile: Add atest_exp2, test-reduce. * math/atest_exp2.c: New file. * math/test-reduce.c: New file. * sysdeps/libm-ieee754/Dist: New file. * sysdeps/libm-ieee754/s_exp2.c: New file. * sysdeps/libm-ieee754/s_exp2f.c: New file. * sysdeps/libm-ieee754/t_exp2.h: New file. * sysdeps/libm-ieee754/t_exp2f.h: New file. * math/libm-test.c (exp2_test): Add some more tests. * Rules: Use empty.os instead of empty.o, since it gets linked into libc.so... * configure.in: Add --disable-static to disable building .a files. * config.make.in: Substitute the new variable. * Makeconfig: Don't build .o files if not building .a files. * elf/dl-runtime.c (fixup): Factor out call to elf_machine_relplt. (profile_fixup): Likewise. 1997-09-23 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/globtest.c (main): Change to directory passed as first argument. * posix/globtest.sh: Don't cd before running the program, instead pass testdir as argument, so that $common_objpfx remains valid. 1997-09-23 18:01 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nis_call.c (__do_niscall2): Fix multiple Server support. * nis/nis_findserver.c: Save latest working sockaddr_in. 1997-09-17 22:07 Zack Weinberg <zack@rabi.phys.columbia.edu> * configure.in: Automatically determine whether as and ld are the GNU versions. (options): --with-gnu-{as,ld,binutils} replaced by single option --with-binutils=PATH specifying a -B option to gcc. * aclocal.m4: Two new macros defined, LIBC_PROG_FOO_GNU and LIBC_PROG_BINUTILS. * configure.in: Allow the user to force configuration for unsupported platforms with an undocumented option. 1997-09-22 16:55 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * sunrpc/get_myaddr.c (get_myaddress): Avoid loopback interfaces, return loopback address only if there is no other interface. * nis/Makefile: Add nis_callback libnsl-routines. * nis/nis_add.c: Use new __do_niscall* interface. * nis/nis_cache.c: Likewise. * nis/nis_checkpoint.c: Likewise. * nis/nis_lookup.c: Likewise. * nis/nis_mkdir.c: Likewise. * nis/nis_modify.c: Likewise. * nis/nis_ping.c: Likewise. * nis/nis_remove.c: Likewise. * nis/nis_rmdir.c: Likewise. * nis/nis_server.c: Likewise. * nis/nis_util.c: Likewise. * nis/rpcsvc/nis.h: Make C++ safe. * nis/nss_nisplus/nisplus-publickey.c (getsecretkey): Fix use of variables. * nis/nis_findserv.c: Make thread safe. * nis/nis_call.c: Add support for callback, Fix use of variables. * nis/nis_table.c: Add support for callback, FOLLOW_PATH and ALL_RESULTS. * nis/nis_callback.c: New, callback functions. * nis/nis_intern.h: Add callback declarations. 1997-09-20 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * string/bits/string2.h: Fix logic in preprocessor directive. (__strsep_1c, __strsep_g): Don't declare __retval as pointing to const, to save a cast and a possible warning. 1997-09-22 04:12 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/i486/atomicity.h (exchange_and_add): Really address memory in xadd not %1. 1997-09-21 13:56 Ulrich Drepper <drepper@cygnus.com> * manual/maint.texi (Supported Configurations): Add SPARC64 to list of supported platforms.
