GNU 4.6 (consequently Xilinx 2019.1) is finally supported
- if GNU version is less than 6.2: * Catch2 is disabled, a custom unit test is used instead, * Constexpr keyword is largely removed and less used (performance loss), * Only ML Cordic/Roms are compiled and tested. - Perfect compilation on g++ v4.6.4, should work on Vivado HLS (g++ v4.6.3).
