Overview
macstl is a C++ source library designed to bring the Mac and SIMD into the world of modern generic programming.
macstl offers a new implementation of std::valarray optimized for SIMD on PowerPCs and Pentiums. It runs 3.6x to 16.2x faster than hand-coded scalar loops. A portable SIMD vec class lets you work with low-level SIMD instructions equivalently cross-platform.
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 in macstl
Version 0.3.1:
- Fixed class scope vector typedefs, missing PowerPC intrinsics header, vector initializer syntax for FSF 3.4 [ILi*].
- Added complex conj function for vec and valarray [ILi*].
- Improved valarray expression performance: v1 [slice].
- Improved valarray code generation: CSE, inlining limits, literal terms, array term elements, statarray construction, compiling -faltivec without -maltivec for Apple gcc 4.0.
- Added refarray class [PBa].
- Fixed buffer overflow in integral valarrays for SSE2; added optimizations for valarray expressions: v1 >> k and v1 << k for sse2 [msh].
- Fixed accumulate array dispatch, integer constant overflow, literal benchmark test for SSE2; fixed chunking iterator pessimization for gcc 3.3/4 [ILi, RBe].
- Added makefile for Linux x86 [ILi*].
- Added support for FSF gcc 3.4 on Cygwin 1.5.
- Added differently typed valarray construct and assign from terms, valarrays of sized booleans, select with sized booleans [ILi].
- Fixed unix makefile directory.
- Added macstlizer conversions: abs, abss, cmpeq, max, min.
- Improved readme file.

Let's see. If one in a million code geeks needs your feeble help in making use of STL, you'll collect, let's see, a couple hundred bucks. If it's one in a thousand, you're rich, but then I fear for the future of software development. Me, I have to use lye soap to wash my hands every time I use C++.
