| * Add target_compile_features command.Stephen Kelly2014-04-0749-0/+342
| | | | | | | | | | | | | | | | | | | | | | This can be used to set the compiler features required by particular targets. An error is issued at CMake time if the compiler does not support the required feature. If a language dialect flag is required by the features used, that will be added automatically. Base the target_compile_features command on cmTargetPropCommandBase. This gives us 'free' handling of IMPORTED, ALIAS, INTERFACE, non-compilable and missing targets.
| * cmTargetPropCommandBase: Change the interface to return bool.Stephen Kelly2014-04-0710-16/+22
| | | | | | | | | | This is needed for the target_compile_features command, which may fail at configure time if an invalid feature is specified.
| * cmTarget: Transitively evaluate compiler features.Stephen Kelly2014-04-0721-14/+203
| | | | | | | | | | | | | | | | | | | | | | Extend the interface of the target_compile_features command with PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES target property if they are set. Consume the INTERFACE_COMPILER_FEATURES target property from linked dependent targets to determine the final required compiler features and the compile flag, if needed. Use the same pattern of origin-debugging which is used for other build properties.
| * cmTarget: Allow populating COMPILE_FEATURES using generator expressions.Stephen Kelly2014-04-0710-9/+44
| | | | | | | | | | | | Delay validation of the content as a feature if it contains a generator expression. It will be checked again at generate-time after evaluation.
| * Features: Add cxx_auto_type.Stephen Kelly2014-04-0716-2/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the availability of this feature for GNU 4.8 on (UNIX AND NOT APPLE) only. In the future, availability can be recorded for earlier GNU, for other platforms and for other compilers. Initially the affected configurations are as restricted as possible to allow for easy testing while extending the features vector in only one dimension. The error message when using the set_property API directly is not very good, but follow up commits will provide origin debugging of the property and a target_compile_features command which will provide a configure-time backtrace when possible.
| * cmTarget: Add COMPILE_FEATURES target property.Stephen Kelly2014-04-077-0/+184
| | | | | | | | | | | | | | Use the contents of it to upgrade the CXX_STANDARD target property, if appropriate. This will have the effect of adding the -std=c++11 compile flag or other language specification on GNU when that is needed for the feature.
| * project: Add infrastructure for recording CXX compiler featuresStephen Kelly2014-04-077-0/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a feature test using the compiler macros and the preprocessor to determine available features. Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable containing all features known to CMake. Add language standard specific variables for internal use to determine the standard-specific compile flags to use. This will be extended to other languages in the future. Follow-up commits will add features which will be recorded by the feature test.
| * cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties.Stephen Kelly2014-04-0715-0/+137
| | | | | | | | | | These are used to determine whether to add -std=c++11, -std=gnu++11 etc flags on the compile line.
| * Add some COMPILE_OPTIONS for specifying C++ dialect.Stephen Kelly2014-04-073-0/+30
| | | | | | | | | | These are compiler-specific, compiler version specific, extension specific and standard version specific.

| * Don't load Clang-CXX from AppleClang-CXX.Stephen Kelly2014-04-072-1/+11
| | | | | | | | | | The Clang-CXX module is going to get version-specific checks, and the version system for AppleClang is not the same as Clang.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenBSD defines Elf64_Dyn::d_tag to be of an unsigned type, which differs from what most other platforms do and what is the case for 32 bit. To have the tag as unsigned makes sense, but this causes a compilation warning: /.../CMake/Source/cmELF.cxx: In member function 'const cmELF::StringEntry* cmELFInternalImpl<Types>::GetDynamicSectionString(int) [with Types = cmELFTypes64]': /.../CMake/Source/cmELF.cxx:945: instantiated from here /.../CMake/Source/cmELF.cxx:668: warning: comparison between signed and unsigned integer expressions Add an explicit typedef to cast the value to for 32 and 64 bit. That type is unsigned and has the proper length for both platforms so no information is lost. Explicitely cast both arguments before comparing them to avoid the warning in all situations.

Since the "r" command replaces existing objects of the same name in an archive, if multiple objects have the same file name and appear in separate append steps then one overwrites the other. Instead, use "ar cq ..." and "ar q ..." to always append to the archive. We already remove the archive before creating it so this will not cause objects to be appended to existing archives on incremental rebuilds.

This evaluation requires the presence of cmGeneratorTarget objects since commit bf98cc25 (Genex: Evaluate TARGET_OBJECTS as a normal expression., 2014-02-26). Ensure that we don't attempt to evaluate the TARGET_OBJECTS generator expression at configure-time, as can happen if CMP0024 or CMP0026 are OLD. Use old-style parsing of the source item to extract object target names in that case. Avoid calling GetProperty("SOURCES") to bypass warnings from CMP0051. Refactor existing logic in GetLanguages which is similar in intent to the new GetSourceFiles code.
