2000-10-28 Jes Sorensen <jes@linuxcare.com> * sysdeps/unix/sysv/linux/ia64/Versions: Export ioperm, iopl, inb, inw, inl, _inb, _inw, _inl, outb, outw, outl, _outb, _outw, _outl. Reported by Bill Nottingham. 2000-04-06 Andreas Schwab <schwab@suse.de> * sysdeps/ia64/dl-machine.h (TRAMPOLINE_TEMPLATE): Save and restore register r8 for functions that return a structure. 2000-10-12 Jakub Jelinek <jakub@redhat.com> * math/libm-test.inc (M_PI_6l, M_E2l, M_E3l, M_2_SQRT_PIl, M_SQRT_PIl): Increase precision. (cbrt_test): If cbrt is not implemented, don't test it. Add L suffix to double constants in results which differ from their L suffixed counterparts. (exp10_test, fmod_test, frexp_test, hypot_test, sqrt_test): Likewise. * sysdeps/sparc/sparc64/fpu/libm-test-ulps: Update. 2000-10-11 Jakub Jelinek <jakub@redhat.com> * inet/rexec.c (rexec_af): Convert rport to host order before passing it to snprintf. 2000-10-14 Ulrich Drepper <drepper@redhat.com> * sysdeps/gnu/netinet/tcp.h: Use u_intXX_t types instead of uintXX_t since this is what <sys/types.h> defines and we include this header. Reported by Bernhard Rosenkraenzer <bero@redhat.de>. * intl/localealias.c (read_alias_file): Update string pointers in map[] if realloc() changed the values. Patch by Jakub Jelinek <jakub@redhat.com>. * manual/stdio.texi: Update printf extension documentation after z became a valid modifier. Patch by Joseph S. Myers <jsm28@cam.ac.uk>. * timezone/africa: Update from tzcode2000g and tzdata2000g. * timezone/asia: Likewise. * timezone/australasia: Likewise. * timezone/backward: Likewise. * timezone/europe: Likewise. * timezone/iso3166.tab: Likewise. * timezone/northamerica: Likewise. * timezone/southamerica: Likewise. * timezone/zone.tab: Likewise.
