After successful compilation of stdlib and Fortran On Web Using LFortran, we focused on improving the support for compile time computation and we are excited to announce that LFortran can now compile the example from the Computing at compile time Fortran Discourse topic.
This example can be used to benchmark the speed of compilation and compile-time array evaluation by increasing the size of the arrays. On this particular example LFortran outperforms other open-source Fortran compilers by an order of magnitude for large array sizes. For small array sizes each compiler has a different constant overhead, which becomes negligible for large arrays and this benchmark measures how quickly the compiler can internally apply the symbolic function on a large array numerically.
