cbench

Numerous major enhancements.

This release makes cbench work with gcc-3.2, so it can be compared in
terms of performance with older gccs.

New micro benchmarks for regex and simpler glibc functions (sscanf, cos, sqrt, hypot, and rand).

For this release, more micro benchmarks were added. The focus was on C code benchmarks (like strpbrk, isalpha, and strftime) and floating operations (like sin and floor). A bug in the HTML reporting was fixed.

The source is now sorted in a way that allows a C
compiler to compile the C benchmarks and ignore
the C++ benchmarks. Some new micro benchmarks were
added, including recursive functions calls, and
creating and iterating over a slist. (slist is a
widely available, but non-standard extension to
the STL.)
