Top community discussions about macstl

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

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
