* On i386, gcc truncates long double constants to double precisionDavid Schultz2008-08-024-8/+127
| | | | | | | | | | | | | | | | | | | at compile time regardless of the dynamic precision, and there's no way to disable this misfeature at compile time. Hence, it's impossible to generate the appropriate tables of constants for the long double inverse trig functions in a straightforward way on i386; this change hacks around the problem by encoding the underlying bits in the table. Note that these functions won't pass the regression test on i386, even with the FPU set to extended precision, because the regression test is similarly damaged by gcc. However, the tests all pass when compiled with a modified version of gcc. Reported by: bde Notes: svn path=/head/; revision=181152
* Detect if the application has cleared the environ variable by settingSean Farley2008-08-021-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | the first value (environ[0]) to NULL. This is in addition to the current detection of environ being replaced, which includes being set to NULL. Without this fix, the environment is not truly wiped, but appears to be by getenv() until an *env() call is made to alter the enviroment. This change is necessary to support those applications that use this method for clearing environ such as Dovecot and Postfix. Applications such as Sendmail and the base system's env replace environ (already detected). While neither of these methods are defined by SUSv3, it is best to support them due to historic reasons and in lieu of a clean, defined method. Add extra units tests for clearing environ using four different methods: 1. Set environ to NULL pointer. 2. Set environ[0] to NULL pointer. 3. Set environ to calloc()'d NULL-terminated array. 4. Set environ to static NULL-terminated array. Noticed by: Timo Sirainen MFC after: 3 days Notes: svn path=/head/; revision=181150
* Fix some problems with asinf(), acosf(), atanf(), and atan2f():David Schultz2008-08-014-71/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | - Adjust several constants for float precision. Some thresholds that were appropriate for double precision were never changed when these routines were converted to float precision. This has an impact on performance but not accuracy. (Submitted by bde.) - Reduce the degrees of the polynomials used. A smaller degree suffices for float precision. - In asinf(), use double arithmetic in part of the calculation to avoid a corner case and some complicated arithmetic involving a division and some buggy constants. This improves performance and accuracy. Max error (ulps): asinf acosf atanf before 0.925 0.782 0.852 after 0.743 0.804 0.852 As bde points out, it's cheaper for asin*() and acos*() to use polynomials instead of rational functions, but that's a task for another day.

* Convert popen()'s `pidlist' to a SLIST, for consistency.Ed Schouten2008-07-291-11/+13
| | | | | | | | | | | | | | | | I guess the original author of the popen() code didn't want to use our <sys/queue.h> macro's, because the single linked list macro's didn't offer O(1) deletion. Because I introduced SLIST_REMOVE_NEXT() some time ago, we can now use the macro's here. By converting the code to an SLIST, it is more consistent with other parts of the C library and the operating system.
