[CMake] Bump CMake minimum version to 3.13.4 This upgrade should be friction-less because we've already been ensuring that CMake >= 3.13.4 is used.

Harmonize cmake_policy() across standalone builds of all projects Move `cmake_policy()` settings from `llvm/CMakeLists.txt` into a shared `cmake/modules/CMakePolicy.cmake`. Include it from all relevant projects that support standalone builds, in order to ensure that the policies are consistently set whether they are built in-tree or stand-alone.

[CMake] Remove dead code setting policies to NEW cmake_minimum_required(VERSION) calls cmake_policy(VERSION), which sets all policies up to VERSION to NEW. LLVM started requiring CMake 3.13 last year, so we can remove a bunch of code setting policies prior to 3.13 to NEW as it no longer has any effect.

[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.

If the provided paths are absolute, everything works fine, however for buildbots it is customary to work with relative paths, and that makes it difficult for CMake to find the right modules to include.

[flang][driver] Delete `f18` (i.e. the old Flang driver) 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.

[flang][driver] Add the new flang compiler and frontend drivers 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”).

[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] Refine output file generation This patch cleans-up the file generation code in Flang's frontend driver. It improves the layering between `CompilerInstance::CreateDefaultOutputFile`, `CompilerInstance::CreateOutputFile` and their various clients. * Rename `CreateOutputFile` as `CreateOutputFileImpl` and make it private. This method is an implementation detail. * Instead of passing an `std::error_code` out parameter into `CreateOutputFileImpl`, have it return Expected<>. This is a bit shorter and idiomatic LLVM. * Make `CreateDefaultOutputFile` (which calls `CreateOutputFileImpl`) issue an error when file creation fails. The error code from `CreateOutputFileImpl` is used to generate a meaningful diagnostic message. * Remove error reporting from `PrintPreprocessedAction::ExecuteAction`. This is only for cases when output file generation fails. This is handled in `CreateDefaultOutputFile` instead (see the previous point). * Inline `AddOutputFile` into its only caller, `CreateDefaultOutputFile`. * Switch from `lvm::buffer_ostream` to `llvm::buffer_unique_ostream>` for non-seekable output streams. This simplifies the logic in the driver and was introduced for this very reason in [1] * Moke sure that the diagnostics from the prescanner when running `-E` (`PrintPreprocessedAction::ExecuteAction`) are printed before the actual output is generated. * Update comments, add test. NOTE: This patch relands [2]. As suggested by Michael Kruse in the post-commit/post-revert review, I've added the following: ``` config.errc_messages = "@LLVM_LIT_ERRC_MESSAGES@" ``` in Flang's `lit.site.cfg.py.in`. This way, `%errc_ENOENT` in output-paths.f90 gets the correct value on Windows as well as on Linux.

[flang] Manual backport of sch_llvm branch Original-commit: flang-compiler/f18@17ee2d8e3ac5bfb633cc2792ee7873c543696e72 Reviewed-on: https://github.com/flang-compiler/f18/pull/78 Tree-same-pre-rewrite: false

[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] Refine output file generation This patch cleans-up the file generation code in Flang's frontend driver. It improves the layering between `CompilerInstance::CreateDefaultOutputFile`, `CompilerInstance::CreateOutputFile` and their various clients. * Rename `CreateOutputFile` as `CreateOutputFileImpl` and make it private. This method is an implementation detail. * Instead of passing an `std::error_code` out parameter into `CreateOutputFileImpl`, have it return Expected<>. This is a bit shorter and idiomatic LLVM. * Make `CreateDefaultOutputFile` (which calls `CreateOutputFileImpl`) issue an error when file creation fails. The error code from `CreateOutputFileImpl` is used to generate a meaningful diagnostic message. * Remove error reporting from `PrintPreprocessedAction::ExecuteAction`. This is only for cases when output file generation fails. This is handled in `CreateDefaultOutputFile` instead (see the previous point). * Inline `AddOutputFile` into its only caller, `CreateDefaultOutputFile`. * Switch from `lvm::buffer_ostream` to `llvm::buffer_unique_ostream>` for non-seekable output streams. This simplifies the logic in the driver and was introduced for this very reason in [1] * Moke sure that the diagnostics from the prescanner when running `-E` (`PrintPreprocessedAction::ExecuteAction`) are printed before the actual output is generated. * Update comments, add test. NOTE: This patch relands [2]. As suggested by Michael Kruse in the post-commit/post-revert review, I've added the following: ``` config.errc_messages = "@LLVM_LIT_ERRC_MESSAGES@" ``` in Flang's `lit.site.cfg.py.in`. This way, `%errc_ENOENT` in output-paths.f90 gets the correct value on Windows as well as on Linux.

[cmake] Don't export `LLVM_TOOLS_INSTALL_DIR` anymore First of all, `LLVM_TOOLS_INSTALL_DIR` put there breaks our NixOS builds, because `LLVM_TOOLS_INSTALL_DIR` defined the same as `CMAKE_INSTALL_BINDIR` becomes an *absolute* path, and then when downstream projects try to install there too this breaks because our builds always install to fresh directories for isolation's sake. Second of all, note that `LLVM_TOOLS_INSTALL_DIR` stands out against the other specially crafted `LLVM_CONFIG_*` variables substituted in `llvm/cmake/modules/LLVMConfig.cmake.in`. @beanz added it in d0e1c2a550ef348aae036d0fe78cab6f038c420c to fix a dangling reference in `AddLLVM`, but I am suspicious of how this variable doesn't follow the pattern. Those other ones are carefully made to be build-time vs install-time variables depending on which `LLVMConfig.cmake` is being generated, are carefully made relative as appropriate, etc. etc. For my NixOS use-case they are also fine because they are never used as downstream install variables, only for reading not writing. To avoid the problems I face, and restore symmetry, I deleted the exported and arranged to have many `${project}_TOOLS_INSTALL_DIR`s. `AddLLVM` now instead expects each project to define its own, and they do so based on `CMAKE_INSTALL_BINDIR`. `LLVMConfig` still exports `LLVM_TOOLS_BINARY_DIR` which is the location for the tools defined in the usual way, matching the other remaining exported variables. For the `AddLLVM` changes, I tried to copy the existing pattern of internal vs non-internal or for LLVM vs for downstream function/macro names, but it would good to confirm I did that correctly.

[flang][driver] Delete `f18` (i.e. the old Flang driver) 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.

[flang][driver] Add the new flang compiler and frontend drivers 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.

[flang][driver] Delete `f18` (i.e. the old Flang driver) 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.

[flang][driver] Add the new flang compiler and frontend drivers 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”).

[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.

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.

[flang] Use CMake to determine endianness. The preprocessor definitions __BYTE_ORDER__, __ORDER_BIG_ENDIAN__, and __ORDER_LITTLE_ENDIAN__ are gcc extensions (also supported by clang), but msvc (and others) do not define them. As a result __BYTE_ORDER__ and __ORDER_BIG_ENDIAN__ both evaluate to 0 by the prepreprocessor, and __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, the first `#if` condition to 1, hence assuming the wrong byte order for x86(_64). This patch instead uses CMake's TestBigEndian module to determine target architecture's endianness at configure-time. Note this also uses the same mechanism for the runtime. If compiling flang as a cross-compiler, the runtime for the compile-target must be built separately (Flang does not support the LLVM_ENABLE_RUNTIMES mechanism yet).

[flang] Fix release build flags. Summary: This patch removes the custom CMAKE_RELEASE_CXX_FLAGS variable. This variable being set was having the effect of removing other important Release flags, notably `-DNDEBUG`. This patch may need to be accompanied by fixes for the macOS issues that the removed comment mentions; I don't have a mac to test this on though so hopefully a reviewer can help with that.

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.

[flang] Fix release build flags. Summary: This patch removes the custom CMAKE_RELEASE_CXX_FLAGS variable. This variable being set was having the effect of removing other important Release flags, notably `-DNDEBUG`. This patch may need to be accompanied by fixes for the macOS issues that the removed comment mentions; I don't have a mac to test this on though so hopefully a reviewer can help with that.

[flang][driver] Add support for Frontend Plugins Introducing a plugin API and a simple HelloWorld Plugin example. This patch adds the `-load` and `-plugin` flags to frontend driver and the code around using custom frontend actions from within a plugin shared library object. It also adds to the Driver-help test to check the help option with the updated driver flags. Additionally, the patch creates a plugin-example test to check the HelloWorld plugin example runs correctly. As part of this, a new CMake flag (`FLANG_BUILD_EXAMPLES`) is added to allow the example to be built and for the test to run. This Plugin API has only been tested on Linux.

[flang] Disable Plugins in out-of-tree builds https://reviews.llvm.org/D106137 added support for plugins in Flang. The CMake configuration for plugins requires some LLVM variables that are not available in out-of-tree builds (e.g. `LLVM_SHLIB_OUTPUT_INTDIR`). This has caused the out-of-tree BuildBot worker to start failing: * https://lab.llvm.org/buildbot/#/builders/175 This patch effectively disables plugins in out-of-tree builds and fixes the configuration error. In order to support plugins in out-of-tree builds, we would have to find a way to access the missing CMake variables from LLVM. This could be implemented at a later time.
