The gfortran front end to gcc reads in the source code and converts it to an abstract syntax tree, which is then converted to an intermediate representation which gcc then further optimizes and converts into assembler. However, there are certain optimizations that require knowledge of Fortran semantics and which are better handled at the level of the abstract syntax tree because the rest of...
We'll present the goals, current status and future plans for Flang, the LLVM Fortran front-end.
Flang is the new LLVM-based Fortran front-end supporting full Fortran 2018. It is being written from scratch in modern C++ and will make extensive use of existing LLVM tools (MLIR, LLVM IR, utility libraries, and so on). We expect this to be the last Fortran front-end that will ever need to be...
We are developing a modern open-source Fortran compiler called LFortran
(https://lfortran.org/). This front-end compiler will enable the interactive
execution of code in environments like Jupyter. This will allow exploratory work
(much like Python, MATLAB or Julia) which is currently not feasible. The
interactivity of our compiler does not impede compilation of binaries with the
goal to...
