| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two optimizations to MI strlen(3) inspired by David S. Miller's 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.

* MFC r206760: getcwd(3): Clarify that EACCES may or may not be checked.Jilles Tjoelker2010-05-051-3/+11
| | | | | | | | | | | | | | | | | | POSIX permits but does not require checking access on the current and parent directories. Because various programs do not like it if getcwd(3) fails, it seems best to avoid checking access as much as possible. There are various reports in GNATS about this (search for getcwd). Our getcwd(3) implementation first queries the kernel for the pathname directly, which does not check any permissions but sometimes fails, and then falls back to reading all parent directories for the names.

| | | | | | | | | | | | | | | | | | | | - The OPSZ macro actually only does the right thing for int32 and int64 operands but not for double and extended double ones. Instead of trying to fix the macro just nuke it and unroll the loops in the correct way though as extended double operands turn out to be the only special case. - For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded after setting type accordingly as it's generally decoded using the low 2 bits as the type, which are 0 for these three instructions. - Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be re-decoded using not only the operand mask appropriate for int64 but also the correct register number encoding. - Use const where appropriate. - Wrap long lines.
