macstl is a C++ header library designed to bring the world of generic programming to the Macintosh, and deliver the surprising speed of SIMD in an intuitive cross-platform package. For example, a simple loop calculating a trigonometric function over an array can be speeded up 450 times. Generic programming is the art - some say, the black art - of making software components super-reusable and yet ultra-efficient. Our tool is the C++ template, and our result is code nearly as fast as hand-coded machine language. macstl was inspired by the premier generic library, the Standard Template Library (now part of the C++ Standard Library), but with a distinct Macintosh flavor. Many components let you use low-level Mac OS X functionality like SIMD acceleration and memory copy-on-write easily and intuitively. Although macstl started on the Mac, it now has a cross-platform look. Over 14,000 source lines of code compile cleanly on different C++ compilers. The SIMD classes work seamlessly on PowerPCs running Mac OS X and Pentiums running Windows XP. macstl provides these sets of classes: - valarray - numeric arrays highly optimized for SIMD architectures like Altivec and MMX/SSE/SSE2/SSE3. - vec - a portable, extensible SIMD toolkit with intuitive, fast functions; some of the trig functions cant be beat so far… - mach - allocator and partially specialized vector for fast OS-level copy-on-write. - core - adapting Core Foundation and Foundation classes for STL. - com - interface pointer and a fast, lightweight server implementation for Microsoft COM and Apple CFPlugIns. - mmapping - treating files as STL containers. - macstlizer - scripts to convert Altivec C source code into macstl C++ source code, headers to map Altivec to SSE intrinsics. - … and more. Whats New in This Release: - 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.. A C++ header library to bring the world of generic programming to the Macintosh.
