* Fix printing of long doubles to match the size thatAndrew Gallatin2004-07-192-11/+8
| | | | | | | | | | | | | | | | gcc is using. This fixes devstat consumers (like vmstat, iostat, systat) so they don't print crazy zillion digit numbers for disk transfers and bandwidth. According to gcc, long doubles are 64-bits, rather than 128 bits like the SVR4 ABI spec wants them to be.. Note that MacOSX also treats long doubles as 64-bits, and not 128 bits, so we are in good company. Reviewed by: das Approved by: grehan Notes: svn path=/head/; revision=132421

| | | | | | | | | | | | | | | | | | 1. Add global varible _libkse_debug, debugger uses the varible to identify libpthread. when the varible is written to non-zero by debugger, libpthread will take some special action at context switch time, it will check TMDF_DOTRUNUSER flags, if a thread has the flags set by debugger, it won't be scheduled, when a thread leaves KSE critical region, thread checks the flag, if it was set, the thread relinquish CPU. 2. Add pq_first_debug to select a thread allowd to run by debugger. 3. Some names prefixed with _thr are renamed to _thread prefix. which is allowed to run by debugger.

* Make regular expression matching aware of multibyte characters. The generalTim J. Robbins2004-07-125-324/+478
| | | | | | | | | | | | | | | | | | | | idea is that we perform multibyte->wide character conversion while parsing and compiling, then convert byte sequences to wide characters when they're needed for comparison and stepping through the string during execution. As with tr(1), the main complication is to efficiently represent sets of characters in bracket expressions. The old bitmap representation is replaced by a bitmap for the first 256 characters combined with a vector of individual wide characters, a vector of character ranges (for [A-Z] etc.), and a vector of character classes (for [[:alpha:]] etc.). One other point of interest is that although the Boyer-Moore algorithm had to be disabled in the general multibyte case, it is still enabled for UTF-8 because of its self-synchronizing nature. This greatly speeds up matching by reducing the number of multibyte conversions that need to be done. Notes: svn path=/head/; revision=132019
