A new C++ source library designed to bring the Macintosh into the world of modern generic programming. macstl gives you the elegance and efficiency of programming with templates. macstl is distinctly mac as well -- you program with Mac OS X concepts and technologies using a cutting-edge interface. macstl offers a new implementation of std::valarray optimized for the Altivec. It runs inline arithmetic 7.76x faster than gcc 3.1 and inline transcendentals 14.21x faster than gcc 3.1. Even with Altivec optimizations off, it is almost 2x faster than gcc, due to the ruthless weeding out of redundant loads and stores. The Mach copy-on-write vector is a partial specialization of std::vector for the Mach allocator. It neatly uses the OS vm_copy facility to "get around" thread safety issues when doing copy-on-write and reference counting. As a result, std::vector can be copied, passed back by value and enlarged without the same overheads. What's New: Version 0.1.4 adds the following: Now builds with Xcode 1.0. Fixed altivec functions not compiling in gcc 3.1: „tree_list not supported by dump_expr‰. Reduced download size by removing build directories. Fixed altivec abs ambiguity. Fixed internal valarray #includes. Fixed uninitialized_copy_n not compiling with non-random access iterators.  |  |
