[Flang][OpenMP][Lower] Refactor lowering of compound constructs (#87070) This patch simplifies the lowering from PFT to MLIR of OpenMP compound constructs (i.e. combined and composite). The new approach consists of iteratively processing the outermost leaf construct of the given combined construct until it cannot be split further. Both leaf constructs and composite ones have `gen...()` functions that are called when appropriate. This approach enables treating a leaf construct the same way regardless of if it appeared as part of a combined construct, and it also enables the lowering of composite constructs as a single unit. Previous corner cases are now handled in a more straightforward way and comments pointing to the relevant spec section are added. Directive sets are also completed with missing LOOP related constructs. GitOrigin-RevId: c8dca5bc0733e2fba81008fc33fcad1f45ba666a
Flang is a ground-up implementation of a Fortran front end written in modern C++. It started off as the f18 project (https://github.com/flang-compiler/f18) with an aim to replace the previous flang project (https://github.com/flang-compiler/flang) and address its various deficiencies. F18 was subsequently accepted into the LLVM project and rechristened as Flang.
Please note that flang is not ready yet for production usage.
Read more about flang in the docs directory. Start with the compiler overview.
To better understand Fortran as a language and the specific grammar accepted by flang, read Fortran For C Programmers and flang's specifications of the Fortran grammar and the OpenMP grammar.
Treatment of language extensions is covered in this document.
To understand the compilers handling of intrinsics, see the discussion of intrinsics.
To understand how a flang program communicates with libraries at runtime, see the discussion of runtime descriptors.
If you're interested in contributing to the compiler, read the style guide and also review how flang uses modern C++ features.
If you are interested in writing new documentation, follow LLVM's Markdown style guide.
Consult the Getting Started with Flang for information on building and running flang.
