STL 2019
This release of the STL incorporates new basic operators to accommodate state-of-the-art processor architectures which supports wide accumulators, SIMD (Single Instruction Multiple Data) and VLIW (Very Long Instruction Word). Thus, the new operators provides support for 64-bit accumulator, complex numbers, enhanced 32-bit operations and additional control code operators.
The software package was reworked and now uses CMake toolchain for tool-dependent build scripts and regression tests for each module in the STL.
