C++ source library.

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++.

You're entitled to your views on C++ and STL, but I want to clear up this point: macstl isn't an implementation of STL, rather it's an extension of it. It extends STL and the Standard Library into things like memory mapping, CFArrays and SIMD vectors.
