* Allow strerror(0) and strerror_r(0, ...).Jilles Tjoelker2011-04-052-2/+5
| | | | | | | | | | | | | | | | Of course, strerror_r() may still fail with ERANGE. Although the POSIX specification said this could fail with EINVAL and doing this likely indicates invalid use of errno, most other implementations permitted it, various POSIX testsuites require it to work (matching the older sys_errlist array) and apparently some applications depend on it.

* Two optimizations to MI strlen(3) inspired by David S. Miller'sXin LI2010-03-121-12/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | blog posting [1]. - Use word-sized test for unaligned pointer before working the hard way. Memory page boundary is always integral multiple of a word alignment boundary. Therefore, if we can access memory referenced by pointer p, then (p & ~word mask) must be also accessible. - Better utilization of multi-issue processor's ability of concurrency. The previous implementation utilized a formular that must be executed sequentially. However, the ~, & and - operations can actually be caculated at the same time when the operand were different and unrelated. The original Hacker's Delight formular also offered consistent performance regardless whether the input would contain characters with their highest-bit set, as it catches real nul characters only. These two optimizations has shown further improvements over the previous implementation on microbenchmarks on i386 and amd64 CPU including Pentium 4, Core Duo 2 and i7.
