f8591f8049 mktime: avoid signed integer overflow
* time/mktime.c (__mktime_internal): Do not mishandle the case
where diff == INT_MIN.

Paul Eggert
94c7d826c9 mktime: simplify computation of average
* time/mktime.c (ranged_convert): Use new time_t_avg function
instead of rolling our own (probably-slower) code.

ce73d68397 mktime: do not assume signed right shift propagates sign bit
* time/mktime.c (isdst_differ): New static function.
(__mktime_internal): No need to normalize tm_isdst now.
(__mktime_internal, not_equal_tm): Use isdst_differ to compare
tm_isdst values.

72a22e596c mktime: merge another wrapv change from gnulib

from some compilers.

6860543348 mktime: remove incorrect attempt at unusual arithmetics
* time/mktime.c (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove.
The code didn't really work on such machines anyway.
(TYPE_MINIMUM): Assume two's complement.
(twos_complement_arithmetic): Verify that long_int and time_t
are two's complement (or unsigned, in the latter case).

Paul Eggert
03cf7fe31b mktime: check signed shifts on long_int and time_t, too
* time/mktime.c (SHR): Check that shifts work as desired
on the types long_int and time_t too, as SHR is used on
such types.

f04dfbc244 mktime: do not assume 'long' is wide enough
* time/mktime.c (verify): Move decl up.
(long_int): New type.
(leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it,
to remove assumption in the code that 'long' is wide enough to
store year values.  This assumption is not true on x32 and on
some non-glibc platforms.

(time_t_avg, time_t_add_ok, time_t_int_add_ok): New static functions.
(guess_time_tm, __mktime_internal): Do not assume that signed
integer overflow wraps around; modern compilers generate code
where this assumption is no longer valid.

	[BZ #1061]
	* sysdeps/generic/glob.c (glob): Only a 0 return from

2005-06-23  Paul Eggert  <eggert@cs.ucla.edu>

	[BZ #1033]
	* time/mktime.c: Import from gnulib.
	The following macros are now consistent with other gnulib code.
	This does not change mktime's behavior.
	(TYPE_IS_INTEGER): New macro.
	(time_t_is_integer): Use it.
	(TYPE_TWOS_COMPLEMENT): New macro.
	(twos_complement_arithmetic): Use it.
	(TYPE_ONES_COMPLEMENT): New macro.
	(TYPE_MINIMUM, TYPE_MAXIMUM): Now supports signed-magnitude.
	mktime doesn't use this, but the code now matches other gnulib code.
	(ranged_convert): Pacify GCC 4.0 in a different way, which
	generates a few bytes less code.
	(ranged_convert, __mktime_internal): When calling a function via a
	pointer P, use P () rather than (*P) (), as we now assume C89 or
	better.

	[BZ #541]
	* time/mktime.c (SHR): New macro, which is a portable
	substitute for >> that should work even on Crays.
	(TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it.

e507cc5673 [BZ #473, BZ #487]
2004-10-27  Derek R. Price  <derek@ximbiot.com>
	[BZ #487] This change is imported from gnulib.
	* time/mktime.c (not_equal_tm) [DEBUG]: Remove redundant check.

2004-10-24  Paul Eggert  <eggert@cs.ucla.edu>

	[BZ #473]
	* time/tst-mktime.c (main): Don't assume that mktime fails
	when given time stamps before 1970.  It returns negative
	time_t values instead, for compatibility with BSD.

	* time/tst-mktime2.c: New file.
	* time/Makefile (tests): Add it.

	[BZ #473] Import from gnulib.  Revamp to avoid several problems near
	time_t extrema, and on hosts with 64-bit time_t and 32-bit int.
	This fixes Debian bug 177940.
	* time/mktime.c (TIME_T_MIDPOINT): New macro.
	(ydhms_diff): Renamed from ydhms_tm_diff, with a new signature,
	which avoids overflow problems on hosts with 64-bit time_t and
	32-bit int.  All callers changed.  Now an inline function.
	Verify at compile-time that long int is wide enough to avoid
	these overflow problems.
	(guess_time_tm): New function.
	(__mktime_internal): Use it.  Avoid overflow when computing yday on
	hosts with 64-bit long and 32-bit int.  Remove tests for 69;
	no longer needed.  Use if rather than #ifdef for LEAP_SECONDS_POSSIBLE
	so that the code is checked by more compilers.
	Do not rely on floating point to probe: stick to integer arithmetic,
	to avoid potential porting problems.
	Repair potential overflow correctly in the Southern Hemisphere.
	(localtime_offset): Add a FIXME for the case where time_t is unsigned.

030d37152a [BZ #471] Fix imported from gnulib.
* time/mktime.c (leapyear, ydms_tm_diff): Year is of type
	long int, not int, to avoid problems when tm_year == INT_MAX
	and tm_mon > 12.
	(__mktime_intenral): Compute year using long int arithmetic,
	not int arithmetic, to avoid problems on hosts where time_t
	and long are 64 bits but int is 32.
