9c6ea9facb Fix stack size and address inconsistency due to executable stack 
When a stack is marked executable due to loading a DSO that requires
an executable stack, the logic tends to leave out a portion of stack
after the first frame, thus causing a difference in the value returned
by pthread_getattr_np before and after the stack is marked
executable. It ought to be possible to fix this by marking the rest of
the stack as executable too, but in the interest of marking as less of
the stack as executable as possible, the path this fix takes is to
make pthread_getattr_np also look at the first frame as the underflow
end of the stack and compute size and stack top accordingly.

The above happens only for the main process stack. NPTL thread stacks
are not affected by this change.

f8591f8049 mktime: avoid signed integer overflow 
* time/mktime.c (__mktime_internal): Do not mishandle the case
where diff == INT_MIN.
 2012-05-23 14:36:25 -07:00
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.
 2012-05-23 14:36:25 -07:00
Paul Eggert
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.
 2012-05-23 14:36:24 -07:00
Paul Eggert
72a22e596c mktime: merge another wrapv change from gnulib 
* time/mktime.c (TYPE_MAXIMUM): Rework slightly to avoid diagnostics
from some compilers.
 2012-05-23 14:36:24 -07:00
Paul Eggert
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).
 2012-05-23 14:36:24 -07:00
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.
 2012-05-23 14:36:24 -07:00
Paul Eggert
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.

Paul Eggert
62bdf9a683 mktime: merge wrapv change from gnulib 
* time/mktime.c (WRAPV): New macro.
(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.
