2012-05-26Fix fma test for underflow.Marek Polacek2-1/+8
2012-05-26Fix stack size and address inconsistency due to executable stackSiddhesh Poyarekar5-16/+111
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.

2012-05-23Remove some sparc cob-webs leftover after Joseph's recent changes.David S. Miller1-3/+1
* sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (__libc_sigaction): Remove unused local variables.
2012-05-23Add sysdeps/unix/sysv/linux/x86_64/x32/configureH.J. Lu2-0/+22
2012-05-23mktime: avoid signed integer overflowPaul Eggert2-4/+8
* time/mktime.c (__mktime_internal): Do not mishandle the case where diff == INT_MIN.
2012-05-23mktime: simplify computation of averagePaul Eggert2-3/+5
* time/mktime.c (ranged_convert): Use new time_t_avg function instead of rolling our own (probably-slower) code.
2012-05-23mktime: do not assume signed right shift propagates sign bitPaul Eggert2-6/+18
* 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.
2012-05-23mktime: merge another wrapv change from gnulibPaul Eggert2-1/+5
* time/mktime.c (TYPE_MAXIMUM): Rework slightly to avoid diagnostics from some compilers.
2012-05-23mktime: remove incorrect attempt at unusual arithmeticsPaul Eggert2-9/+13
* 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).
2012-05-23mktime: check signed shifts on long_int and time_t, tooPaul Eggert2-3/+10
* 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.
2012-05-23mktime: do not assume 'long' is wide enoughPaul Eggert2-12/+26
* 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.
2012-05-23mktime: merge wrapv change from gnulibPaul Eggert2-25/+99
* 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.
