2021-08-05[flang][driver] Delete `f18` (i.e. the old Flang driver)Andrzej Warzynski1-5/+2
This patch removes `f18`, a.k.a. the old driver. It is being replaced with the new driver, `flang-new`, which has reached feature parity with `f18` a while ago. This was discussed in [1] and also in [2]. With this change, `FLANG_BUILD_NEW_DRIVER` is no longer needed and is also deleted. This means that we are making the dependency on Clang permanent (i.e. it cannot be disabled with a CMake flag). LIT set-up is updated accordingly. All references to `f18` or `f18.cpp` are either updated or removed. The `F18_FC` variable from the `flang` bash script is replaced with `FLANG_FC`. The former is still supported for backwards compatibility.

2020-09-11[flang][driver] Add the new flang compiler and frontend driversCaroline Concatto1-0/+5
Summary: This is the first patch implementing the new Flang driver as outlined in [1], [2] & [3]. It creates Flang driver (`flang-new`) and Flang frontend driver (`flang-new -fc1`). These will be renamed as `flang` and `flang -fc1` once the current Flang throwaway driver, `flang`, can be replaced with `flang-new`. Currently only 2 options are supported: `-help` and `--version`. `flang-new` is implemented in terms of libclangDriver, defaulting the driver mode to `FlangMode` (added to libclangDriver in [4]). This ensures that the driver runs in Flang mode regardless of the name of the binary inferred from argv[0]. The design of the new Flang compiler and frontend drivers is inspired by it counterparts in Clang [3]. Currently, the new Flang compiler and frontend drivers re-use Clang libraries: clangBasic, clangDriver and clangFrontend. To identify Flang options, this patch adds FlangOption/FC1Option enums. Driver::printHelp is updated so that `flang-new` prints only Flang options. The new Flang driver is disabled by default. To enable it, set `-DBUILD_FLANG_NEW_DRIVER=ON` when configuring CMake and add clang to `LLVM_ENABLE_PROJECTS` (e.g. -DLLVM_ENABLE_PROJECTS=“clang;flang;mlir”).

2020-03-26[flang] A rework of the cmake build components for in and out of tree builds.Patrick McCormick1-8/+0
In general all the basic functionality seems to work and removes some redundancy and more complicated features in favor of borrowing infrastructure from LLVM build configurations. Here's a quick summary of details and remaining issues: * Testing has spanned Ubuntu 18.04 & 19.10, CentOS 7, RHEL 8, and MacOS/darwin. Architectures include x86_64 and Arm. Without access to Window nothing has been tested there yet. * As we change file and directory naming schemes (i.e., capitalization) some odd things can occur on MacOS systems with case preserving but not case senstive file system configurations. Can be painful and certainly something to watch out for as any any such changes continue. * Testing infrastructure still needs to be tuned up and worked on. Note that there do appear to be cases of some tests hanging (on MacOS in particular). They appear unrelated to the build process. * Shared library configurations need testing (and probably fixing). * Tested both standalone and 'in-mono repo' builds. Changes for supporting the mono repo builds will require LLVM-level changes that are straightforward when the time comes. * The configuration contains a work-around for LLVM's C++ standard mode passing down into Flang/F18 builds (i.e., LLVM CMake configuration would force a -std=c++11 flag to show up in command line arguments. The current configuration removes that automatically and is more strict in following new CMake guidelines for enforcing C++17 mode across all the CMake files. * Cleaned up a lot of repetition in the command line arguments. It is likely that more work is still needed to both allow for customization and working around CMake defailts (or those inherited from LLVM's configuration files). On some platforms agressive optimization flags (e.g. -O3) can actually break builds due to the inlining of templates in .cpp source files that then no longer are available for use cases outside those source files (shows up as link errors). Sticking at -O2 appears to fix this. Currently this CMake configuration forces this in release mode but at the cost of stomping on any CMake, or user customized, settings for the release flags. * Made the lit tests non-source directory dependent where appropriate. This is done by configuring certain test shell files to refer to the correct paths whether an in or out of tree build is being performed. These configured files are output in the build directory. A %B substitution is introduced in lit to refer to the build directory, mirroring the %S substitution for the source directory, so that the tests can refer to the configured shell scripts.

2020-03-11[flang] Add Fortran IR (FIR) MLIR dialect implementation ↵jeanPerier1-0/+4
(flang-compiler/f18#1035) Adds FIR library that implements an MLIR dialect to which Fortran parse-tree will be lowered to. FIR is defined and documented inside FIROps.td added in this commit. It is possible to generate a more readable description FIRLangRef.md from FIROps.td following the related instructions added to the README.md by this commit. This patch adds FIR definition and implementation that allow parsing, printing, and verifying FIR. FIR transformations and lowering to Standard and LLVM dialects are not part of this patch. The FIR verifiers are verifying the basic properties of FIR operations in order to provide a sufficient frame for lowering. Verifiers for more advanced FIR properties can be added as needed. Coarrays are not covered by FIR defined in this patch. This patch also adds tco tool that is meant to process FIR input files and drives transformations on it. The tco tool is used for testing. In this patch, it is only used to demonstrate parsing/verifying/ and dumping FIR with round-trip tests. Note: This commit does not reflect an actual work log, it is a feature-based split of the changes done in the FIR experimental branch. The related work log can be found in the commits between: https://github.com/schweitzpgi/f18/commit/742edde572bd74d77cf7d447132ccf0949187fce and https://github.com/schweitzpgi/f18/commit/2ff55242126d86061f4fed9ef7b59d3636b5fd0b Changes on top of these original commits were made during this patch review.

2020-02-17[flang] Add Pre-FIR Tree structure to help lowering the parse-treeJean Perier1-0/+1
The Pre-FIR Tree structure is a transient data structure that is meant to be built from the parse tree just before lowering to FIR and that will be deleted just afterwards. It is not meant to perfrom optimization analysis and transformations. It only provides temporary information, such as label target information or parse tree parent nodes, that is meant to be used to lower the parse tree structure into FIR operations. A PFTBuilder class builds the Pre-Fir Tree from the parse-tree. A pretty printer is available to visualize this data structure. - Lit tests are added to: 1. that the PFT tree structure is as expected 2. that the PFT captures all intented nodes - Cmake changes: Prevent warnings inisde LLVM headers when compiling flang The issue is that some LLVM headers define functions where the usage of the parameters depend on environment ifdef. See for instance Size in: https://github.com/llvm/llvm-project/blob/5f940220bf9438e95ffa4a627ac1591be1e1ba6e/llvm/include/llvm/Support/Compiler.h#L574 Because flang is build with -Werror and -Wunused-parameter is default in clang, this may breaks build in some environments (like with clang9 on macos). A solution would be to add -Wno-unused-parameter to flang CmakLists.txt, but it is wished to keep this warning on flang sources for quality purposes. Fixing LLVM headers is not an easy task and `[[maybe_unused]]` is C++17 and cannot be used yet in LLVM headers. Hence, this fix simply silence warnings coming from LLVM headers by telling CMake they are to be considered as if they were system headers. - drone.io changes: remove llvm 6.0 from clang config in drone.io and link flang with libstdc++ instead of libc++ llvm-dev resolved to llvm-6.0 in clang builds on drone.io. llvm 6.0 too old. LLVM packages are linked with libstdc++ standard library whereas libc++ was used for flang. This caused link time failure when building clang. Change frone.io to build flang with libc++.
