* Features: Add cxx_alignas.Stephen Kelly2014-04-081-0/+1
| | | | | | cxx_alignof will be a separate feature known to CMake, because both can be implemented with separate backward compatibility versions.

* Features: Add cxx_variadic_templates.Stephen Kelly2014-04-081-1/+2
| | | | | | | Expect cxx_variadic_templates to implement N2555. N2555 is essentially a bugfix and predates most compiler releases which aimed to experimentally support variadic templates.

* Export: Populate INTERFACE_COMPILE_FEATURES property.Stephen Kelly2014-04-082-0/+7
|
* Add target_compile_features command.Stephen Kelly2014-04-073-0/+112
| | | | | | | | | | | 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 Kelly2014-04-074-13/+117
| | | | | | | | | | | 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 Kelly2014-04-074-9/+28
| | | | | | 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 Kelly2014-04-071-2/+17
| | | | | | | | | | | | | | 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 Kelly2014-04-074-0/+170
| | | | | | | 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.
* cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties.Stephen Kelly2014-04-073-0/+33
| | | | | These are used to determine whether to add -std=c++11, -std=gnu++11 etc flags on the compile line.

|\ | | | | | | | | | | | | | | | | a4e6bf8e cmTarget: Make GetSourceFiles string overload private. 92e2fbe1 cmGeneratorTarget: Trace cmSourceFile objects instead of strings. c5b26f3b cmTarget: Cache the cmSourceFiles in GetSourceFiles. eb163f37 cmTarget: Extract a ProcessSourceItemCMP0049 method. 19b7c22d Ninja: Query custom commands once per target, not once per file.
| * cmTarget: Make GetSourceFiles string overload private.Stephen Kelly2014-04-061-3/+3
| | | | | | | | | | Consumers should use the cmSourceFile overload, which is now always the case.
| * cmGeneratorTarget: Trace cmSourceFile objects instead of strings.Stephen Kelly2014-04-061-16/+15
| | | | | | | | | | | | | | | | This reverses the decision in commit d38423ec (cmTarget: Add a method to obtain list of filenames for sources., 2014-03-17). The cmSourceFile based API is preferred because that avoids creation of many cmSourceFileLocation objects for matching strings, and the result is cached by cmTarget.
| * cmTarget: Cache the cmSourceFiles in GetSourceFiles.Stephen Kelly2014-04-062-18/+39
| | | | | | | | | | | | Avoid calling GetSourceFiles with the same result container multiple times when tracing target dependencies. The result from the previous configuration is cached and used later otherwise.
| * cmTarget: Extract a ProcessSourceItemCMP0049 method.Stephen Kelly2014-04-062-9/+41
| | | | | | | | | | | | | | | | | | | | Avoid calling AddSource for each src filename. That involves checking each entry for uniqueness and creating a separate generator expression for each one. Instead, add a single entry for the list of sources. The source files are passed through a uniqueness filter at generate-time, so duplicates don't matter so much.
| * Ninja: Query custom commands once per target, not once per file.Stephen Kelly2014-04-052-7/+8
| | | | | | | | | | Computing the source files is now more expensive, so the Ninja generator became very slow with a large number of files.
