Stephen Kelly 10f33eee1d Features: Add cxx_variadic_templates.
Expect cxx_variadic_templates to implement N2555.

N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.

Stephen Kelly 9eaf375598 Export: Populate INTERFACE_COMPILE_FEATURES property. 2014-04-08 11:05:07 +02:00
Stephen Kelly 8ed59fc207 Add target_compile_features command.
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.
2014-04-07 18:11:18 +02:00
Stephen Kelly 4e6ca50445 cmTargetPropCommandBase: Change the interface to return bool.
This is needed for the target_compile_features command, which
may fail at configure time if an invalid feature is specified.
2014-04-07 18:11:18 +02:00
Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
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.
2014-04-07 18:11:18 +02:00
Stephen Kelly baff44345c cmTarget: Allow populating COMPILE_FEATURES using generator expressions.
Delay validation of the content as a feature if it contains a
generator expression. It will be checked again at generate-time
after evaluation.
2014-04-07 18:11:18 +02:00
Stephen Kelly f97bf4370c Features: Add cxx_auto_type.
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.

Stephen Kelly 03355d6b5b cmTarget: Add COMPILE_FEATURES target property.
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.
2014-04-07 16:52:22 +02:00
Stephen Kelly faeddf64f2 project: Add infrastructure for recording CXX compiler features
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.

Stephen Kelly 913394af24 cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties.
These are used to determine whether to add -std=c++11, -std=gnu++11
etc flags on the compile line.
2014-04-07 16:48:44 +02:00
Stephen Kelly 8238a6cd5d Add some COMPILE_OPTIONS for specifying C++ dialect.
These are compiler-specific, compiler version specific, extension specific
and standard version specific.

Stephen Kelly 59b5fdd37c Don't load Clang-CXX from AppleClang-CXX.
The Clang-CXX module is going to get version-specific checks, and
the version system for AppleClang is not the same as Clang.

Stephen Kelly a4e6bf8e36 cmTarget: Make GetSourceFiles string overload private.
Consumers should use the cmSourceFile overload, which is now
always the case.

Stephen Kelly 92e2fbe103 cmGeneratorTarget: Trace cmSourceFile objects instead of strings.
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.

Stephen Kelly c5b26f3bec cmTarget: Cache the cmSourceFiles in GetSourceFiles.
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.

Stephen Kelly eb163f37d4 cmTarget: Extract a ProcessSourceItemCMP0049 method.
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.

Stephen Kelly 19b7c22d02 Ninja: Query custom commands once per target, not once per file.
Computing the source files is now more expensive, so the Ninja
generator became very slow with a large number of files.
