Update.
1997-03-23 02:11 Ulrich Drepper <drepper@cygnus.com> * time/sys/time.h: Make values ITIMER_* also available as macros. * elf/dl-support.c (_dl_sysdep_read_whole_file): Don't call __fstat but instead __fxstat directly to avoid dependency on libc.a when inline failed. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_read_whole_file): Likewise. * math/Makefile (libm-routines): Add s_remquo. * sysdeps/libm-i387/s_remquo.S: New file. * sysdeps/libm-i387/s_remquof.S: New file. * sysdeps/libm-i387/s_remquol.S: New file. * sysdeps/libm-ieee754/s_remquo.c: New file. * sysdeps/libm-ieee754/s_remquof.c: New file. * sysdeps/libm-ieee754/s_remquol.c: New file. * math/libm-test.c (remquo_test): New function. * sysdeps/libm-ieee754/s_rintl.c: Handle implicit leading one correctly. 1997-03-22 14:06 Ulrich Drepper <drepper@cygnus.com> * math/Makefile (libm-calls): Add s_nan. * sysdeps/libm-ieee754/s_nan.c: New file. Implement `nan' function. * sysdeps/libm-ieee754/s_nanf.c: New file. Implement `nanf' function. * sysdeps/libm-ieee754/s_nanl.c: New file. Implement `nanl' function. * math/libm-test.c (basic_tests): Add tests for `nan' function. * math/libm-test.c (copysign_test): New function. (main): Call copysign_test. 1997-03-22 06:28 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_nextafter.c: Return y if x == y. * sysdeps/libm-ieee754/s_nextafterf.c: Likewise. * sysdeps/libm-ieee754/s_nextafterl.c: Likewise. * sysdeps/libm-i387/s_nextafterl.c: Likewise. * math/libm-test.c (fdim_test, fmin_test, fmax_test, nextafter_test): New functions. Test these functions. (main): Call above new functions. 1997-03-22 04:53 Ulrich Drepper <drepper@cygnus.com> * Net release 2.0.2. 1997-03-22 04:37 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/termbits.h (OXTABS): Define as alias for XTABS. * sysdeps/unix/sysv/linux/alpha/termbits.h (OXTABS): Likewise. * termios/sys/ttydefaults.h: Partly revert patch by Andreas Schwab of Sun Dec 15 16:33:44 1996. Proposed by Thomas Bushnell <thomas@gnu.ai.mit.edu>. 1997-03-21 13:41 Roland McGrath <roland@baalperazim.frob.com> * sysdeps/sparc/dl-machine.h (elf_machine_rel): Rewritten as for i386. Check here for non-SHN_UNDEF STB_LOCAL symbols don't do any lookup or consult their values. (elf_machine_lookup_noexec_p, elf_machine_lookup_noplt_p, ELF_MACHINE_RELOC_NOPLT): New macros. * elf/rtld.c (dl_main): Pass ELF_MACHINE_RELOC_NOPLT to _dl_lookup_symbol in place of DL_LOOKUP_NOPLT. * sysdeps/i386/dl-machine.h (ELF_MACHINE_RELOC_NOPLT): New macro. * sysdeps/i386/dl-machine.h (elf_machine_rel): Rewritten to do the symbol lookup before checking reloc type except for R_386_RELATIVE. (elf_machine_lookup_noexec_p, elf_machine_lookup_noplt_p): New macros. * elf/dl-reloc.c (RESOLVE): Remove STB_LOCAL check; let it be per-machine since it supposedly can't happen on i386. * elf/dl-lookup.c (do_lookup): Change arg FLAGS to RELOC_TYPE. Use elf_machine_lookup_{noexec,noplt}_p macros on it. Remove gratuitous indirection from REF arg; change callers. (_dl_lookup_symbol, _dl_lookup_versioned_symbol): Change arg name. (_dl_lookup_symbol_skip, _dl_lookup_versioned_symbol_skip): Remove FLAGS arg altogether. * elf/dlsym.c: Remove argument of FLAGS parameter. * elf/dlvsym.c: Likewise. * elf/link.h: Update decls. * Makefile (distribute): Add BUGS.
