* GNU: Disable depfiles in try-compile mode only for GCCRaul Tambre2020-04-071-1/+2
| | | | | Disabling them causes issues for Clang's CUDA frontend. Since this is a GCC bug, simply check for GCC.
* CUDA: Refactor PTX compilation flag into compiler modulesRaul Tambre2020-04-071-0/+1

* Clang: Refactor CXX standard flags into __compiler_clang_cxx_standards()Raul Tambre2020-04-073-186/+122
| | | | | | | These standard flags are the same for CXX, OBJCXX and CUDA. Refactor them into a single macro to reduce duplication and so we can easily reuse them. Updated bootstrap script to search in the general Clang module instead of the language-specific.

| * XL: Add comment clarifying why we pretend it has full C++11/14 supportBrad King2020-03-311-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | Since commit b0f46c48f6 (CompileFeatures: Now able to presume full language level support, 2019-03-06, v3.15.0-rc1~265^2~1) we pretend that the XL compiler has full C++11 and C++14 support so that projects specifying granular features will at least get the corresponding compiler mode. This is a work around for our lack of a full feature check table for this compiler that works in common cases. Add a comment explaining this. Issue: #20521

* | | XL: Fix using Fortran modules from their output directoryBrad King2020-02-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The XL Fortran compiler's `-qmoddir=` flag sets the module output directory but does not add the directory to the search path for using modules. This is inconsistent with other compilers like the GNU Fortran compiler's `-J` flag that does both. In order to make these consistent, add the module output directory with a `-I` flag on the XL Fortran compiler so that it will be searched when using modules too. This fixes our `FortranModules` test's coverage of submodules on Ninja + XL. That test places module files in a subdirectory that with Ninja is not the current working directory when the compiler runs. Fixes: #20400

| | * Ninja: Do not use nvcc response files with non-nvcc toolsFrancisco Facioni2020-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit d91b5a72cd (Ninja: Add support for CUDA nvcc response files, 2019-05-30, v3.15.0-rc1~8^2) we use NVCC's `--options-file` option to avoid long link command lines via a response file. However, for non-device linking the host tools are used and the option does not make sense. Update the logic to use `--options-file` only for device linking. Linking with the host tools already has its own logic for response files. Fixes: #19954
* | | PCH: Clang: Update PCH usage flags to include original headerSergey Larin2020-02-241-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an additional include flag to PCH usage command line to fix programs that rely on `compile_commands.json` file. Pass it to the preprocessor directly to avoid compiler driver to change it to '-include-pch'. When preprocessor is requested to preprocess a file, it tries to get the original filename from '.pch' and uses that file for preprocessing. CMake generates a '.pch' file from the '.hxx' file by passing an empty '.cxx' source file to the compiler as a compilation unit and the header file with the '-include' flag. After that, compiler puts compilation unit filename in the '.pch' as the original filename. However, CMake build system uses empty file as the source file and passes the header file using '-include-pch' flag. As a result, Clang uses the wrong file for preprocessing and produces the corrupted preprocessed file. Fixes: #20355 Signed-off-by: Sergey Larin <cerg2010cerg2010@mail.ru>

| * | clang-tidy: Add driver mode argumentHanjiang Yu2020-01-276-0/+15
| | | | | | | | | | | | | | | | | | | | | `clang-tidy` does not infer driver mode if it is not provided with a JSON compilation database. This is exactly the way cmake launches it. Hence clang-tidy will only use the default driver mode. Add an explicit driver mode argument to avoid this.

Some compile options need to be passed to GCC using a `-Wc` option. QCC does not support --sysroot, so setting CMAKE_SYSROOT in a toolchain file currently does not work. This means that it is likely that no one is setting CMAKE_SYSROOT in existing QNC toolchain files. Override the GCC option for sysroot in the QCC.cmake file with -Wc,-isysroot. This exposes a further issue in that the QNX SDK does not follow the same architectural folder structure as linux uses. That is, on linux systems, architecture-specific libraries might be in <sysroot>/usr/lib/<arch> such as /usr/lib/x86_64-linux-gnu/libcurl.so CMake models this by suffixing the <arch> onto lib directories when searching for libraries. The QNX SDK is structured differently such that the <arch> should be used as a prefix: <sysroot>/<arch>/usr/lib such as <sysroot>/x86_64/usr/lib/libcurl.so Add a variable for platform configuration to set whether to prefix or suffix the <arch> and set that in the QCC.cmake. Use the directory structure of the QNX SDK to compute the <arch> from the implicit library directories. The assumption is that the arch will be a single directory directly below the CMAKE_SYSROOT, below which the usr/ prefix occurs. It would not be appropriate to instruct users to make the <arch> part of the sysroot when specified in the toolchain file because: 1. That would be non-DRY - The QCC wrapper already determines the <arch> by the -V argument passed to the compiler, specified in the toolchain file as the CMAKE_C_COMPILER_TARGET variable. 2. The includes in the QNX SDK are not below the <arch> directory. So, the location of the <arch> in the full path is different on QNX compared to, say an embedded linux platform, but the intent is the same. Add documentation to recommend the use of CMAKE_SYSROOT in a QNX toolchain file. As the CMAKE_SYSROOT is always the same for QNX, it would be possible to simply set it in QCC.cmake. However, that would change behavior for existing users as when CMAKE_SYSROOT is set, files/paths outside of the CMAKE_SYSROOT do not get found. The <arch> prefixing is only enabled in cmSearchPath.cxx if CMAKE_SYSROOT is set. This ensures that the user gets consistency in the current state without CMAKE_SYSROOT, and gets better consistency when using CMAKE_SYSROOT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with CUDA 10.2 the nvcc compiler has gained support to automatically forward unknown flags to the host compiler. This behavior is highly desired as projcts that mix CUDA, C, C++ run into situation where flags such as `-pthread` which aren't supported by nvcc, are being applied to all source files and therefore break CUDA compilation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ninja generator's support for Fortran requires that source files be preprocessed explicitly first. However, the `xlf` compiler does not have a simple `-E` option or equivalent to do preprocessing. The only documented way to get preprocessed output is to use `-d` to leave it behind, but only at an inflexible location. Instead, create our own `cpp` wrapper script and substitute it for the real preprocessor using `-tF -B ...`. Teach the wrapper to map the `cpp` output to the location we need and then invoke the real `cpp` underneath. Fixes: #19450
