Fri Sep 29 03:43:51 1995 Paul Eggert <eggert@twinsun.com>
Rewrite mktime from scratch for performance, and for correctness in the presence of leap seconds. * time/mktime.c (ydhms_tm_diff, not_equal_tm, print_tm, check_result): New functions. (LEAP_SECONDS_POSSIBLE, CHAR_BIT, INT_MIN, INT_MAX, TIME_T_MIN, TIME_T_MAX, TM_YEAR_BASE, EPOCH_YEAR): New macros. <limits.h>, <stdlib.h>: New #includes. (main): Support tests with given broken-down value; support benchmarks. (__mon_lengths, debugging_enabled, printtm, dist_tm, doit, do_normalization, normalize, BAD_STRUCT_TM, SKIP_VALUE, <ctype.h>): Remove. * time/time.h, time/mktime.c (__mktime_internal): New offset arg. * time/mktime.c (mktime), time/timegm.c (timegm): Use it. * time/mktime.c (__mon_yday): New variable; replaces `__mon_lengths'. time/offtime.c (__offtime), time/tzset.c (compute_change): Use it. * time/offtime.c (__offtime): Remove useless assignment `tp->tm_isdst = -1'. * manual/maint.texi: Update credits. Fri Oct 6 00:28:53 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/unix/common/readv.S: Moved to sysdeps/unix/bsd. * sysdeps/unix/common/writev.S: Moved to sysdeps/unix/bsd. * sysdeps/unix/sysv/linux/readv.c: File removed. * sysdeps/unix/sysv/linux/writev.c: File removed. * sysdeps/unix/configure.in: Check for readv and writev syscalls. * sysdeps/unix/configure.in: If eval doesn't set $unix_srcname, set it to $unix_syscall instead of $unix_function.
