* Cray: Add language standards for the Cray compilerChuck Atkins2017-05-013-0/+50

* Compilers: Add common macros to be used by various compilersChuck Atkins2017-05-011-0/+62
| | | | | | | | | | With numerous compilers now supporting multiple language standards in CMake, some common design patterns have begun to emerge. This is intended to be a collection of macros implementing many of those common design patterns that can be factored out and leveraged by many compilers. Currently this only contains the code to set the default language standard of not preset. More functionality will be added in the future as appropriate.

* XL: Fix the use of the -qhalt flag for varying OSsChuck Atkins2017-04-272-4/+2
| | | | | | | | | | | | | | The valid settings to pass to the IBM XL compiler for the -qhalt flag vary widely by language and platform. Based on existing documentation, the following table shows which error levels are valid to pass to -qhalt= since -qhalt=e is not always available.

* Autogen: Pass explicit predefines header to moc if possibleAleix Pol2017-04-201-0/+2
| | | | | | | | | | | Qt is relying on whoever calls moc to include a file with the predefined values that will be used by the compiler, otherwise moc takes wrong paths and weird things happen. Instead, generate an include file and feed it to all mocs to make sure it's generating correct code. Co-Author: Sebastian Holtermann <sebholt@xwmw.org> Fixes: #16640

| | | | | | | | | | | | The variables recently added by commit b9d36826 (Add 'CMAKE_GCC_AR' and 'CMAKE_GCC_RANLIB' variables, 2017-03-08) are more appropriately managed with language-specific names rather than toolchain-specific names.

| * Features: Update features for Intel C++ 17.0.2 on UNIXBrad King2017-03-311-1/+3
| | | | | | | | | | | | | | Intel 17.0.2 on UNIX introduced a regression from 17.0.1 in its definition of `__cpp_constexpr` in `-std=c++14` mode. It incorrectly defines it as `200704` instead of the expected `201304`. Fix our feature detection table to account for this.

| * SDCC: Fix identification of current sdcc compilerBrad King2017-03-291-2/+8
| | | | | | | | | | | | | | | | The sdcc compiler no longer defines the `SDCC` preprocessor macro. Instead `__SDCC_VERSION_MAJOR` and similar component-wise macros are defined. Use them instead if defined. Issue: #16746
* | GNU-FindBinUtils: Avoid setting policy CMP0054Brad King2017-03-101-3/+1
| | | | | | | | | | | | | | The `cmake_policy(SET)` call triggers `CMP0011` warnings when this module is used in a project that does not set `CMP0011` to NEW. We could avoid these with a `cmake_policy` PUSH/POP pair, but it is simpler to adjust our code to not trigger `CMP0054` in the first place.

* GNUC: also check __GNUG__ define when checking for g++Rolf Eike Beer2017-01-252-0/+15
| | | | | | | At least the scratchbox compiler for the N900, which basically is a gcc 4.2, sets only __GNUG__ in C++ mode, but not __GNUC__. It does indeed set __GNUC_MINOR__ and __GNUC_PATCHLEVEL__. Extend the compiler detection code for GNU compilers in C++ mode to look at __GNUG__ in case __GNUC__ is absent.

* CUDA: Populate NVIDIA compiler information on WindowsBrad King2017-01-121-13/+17
| | | | | | | Port Windows-specific compilation and linking rules over from the `Platform/Windows-MSVC` module and adapt it for NVIDIA CUDA. On Windows nvcc and its host compiler (MSVC) do not understand or use options like `-fPIC` or `-std=`, so condition those out.

* PGI: Add support for Fortran with the Ninja generatorDaniel Carrera2016-12-161-0/+3
| | | | | | | The PGI documentation says that `-Mpreprocess` "instructs the compiler to perform cpp-like preprocessing on assembly and Fortran input source files". The `-E` flag causes the compiler to spit the result to stdout instead of saving it to a file.
* CUDA: Fix default compiler flag initializationBrad King2016-12-091-5/+5
| | | | | | | Since commit v3.7.0-rc1~392^2 (Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files, 2016-07-05) our convention is to initialize compiler flag variables via `string(APPEND)` rather than `set()`. Fix the convention for `CMAKE_CUDA_FLAGS[_<CONFIG>]_INIT`.

| | | | | | | | | Condition all calls to `_record_compiler_features_{c,cxx}` on `_result EQUAL 0` so that adding new language standards later does not need to update them. Avoid some duplicate compiler version checks by conditioning C11 and CXX14 feature recording on the existence of `CMAKE_{C11,CXX14}_STANDARD_COMPILE_OPTION` (whose setting already used the version check).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `__cplusplus` macro is not defined to the language level reliably. When simulating MSVC it is always set to `1`. When simulating GCC it is set to the lower value of the current language level and the maximum level supported by the simulated version of GCC (from observation). For MSVC we already used a combination of `__INTEL_CXX11_MODE__` and `__cpp_aggregate_nsdmi` to detect C++14 mode. Extend this for general use by removing the condition on `_MSC_VER`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common use case of `target_compile_features` is simply to specify that the compiler should be run in a mode that is aware of e.g. C++11. Some projects simply specify a particular C++11-only feature to request this. Provide a first-class way to do this by naming features after the corresponding language standard. Record them as always available in the corresponding standard level so that requesting them always ensures that standard (or higher) is used.
