[flang] Revert "Schauveau cmake" Original-commit: flang-compiler/f18@be33dc182a9bcfa664095886ca62b3b1db4eb797 Reviewed-on: https://github.com/flang-compiler/f18/pull/7

cmake_minimum_required(VERSION 3.9.0)
[flang] A rework of the cmake build components for in and out of tree builds. 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.

[flang] Add cmake option to link with FIR and LLVM The cmake option -DLINK_WITH_FIR=ON causes the f18 driver to be linked against FIR and LLVM. When it is set to OFF (the default), the call into FIR is #ifdef'd out. The source in lib/FIR is always built; this option only affects linking.

[flang] A rework of the cmake build components for in and out of tree builds. 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).

[flang] Add Fortran IR (FIR) MLIR dialect implementation (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.

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).

[flang] A rework of the cmake build components for in and out of tree builds. 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.

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.
