* Simplify CM_FALLTHROUGH implementationBrad King2017-11-301-7/+0
| | | | | | | Use the macro now provided by KWSys instead of using `try_compile` checks. It will no longer consider the `__attribute__((fallthrough))` variant, but compilers that don't have one of the modern attributes shouldn't warn about not using one anyway.
* Use C++11 '= delete' instead of CM_EQ_DELETEBrad King2017-09-281-1/+0
| | | | | We now require C++11 support including `= delete`. Drop use of the old compatibility macro.
* Remove checks for auto_ptr that we no longer needBrad King2017-09-271-1/+0
| | | | We no longer use `auto_ptr` at all, so drop the checks for it.
* C++ feature checks: Filter out warnings caused by user flagsBrad King2017-09-191-0/+2
| | | | | | Filter out `-Winvalid-command-line-argument` warnings from Clang (that can be caused by user-specified flags) so that they do not break our checks for C++ feature availability.
* C++ feature checks: Prepare for multiple check output filtersBrad King2017-09-191-1/+2

* Drop now-unused definition of CM_OVERRIDEBrad King2017-09-151-1/+0

* Use C++11 nullptrDaniel Pfeifer2017-08-241-1/+0

* Use C++11 unordered containersDaniel Pfeifer2017-08-221-2/+0

* C++ feature checks: Improve exclusion of "0 Warning(s)"Brad King2017-06-081-1/+3
| | | | | | | | Simply matching "0 Warning" may match "10 Warning(s)". Instead remove the entire ` 0 Warning(s)` content from the MSBuild output before searching it for warnings. Issue: #16942
* C++ feature checks: Do not match "0 Warning(s)" as a warningWalter Gray2017-06-061-1/+1
| | | | | | | | | The change in commit v3.9.0-rc1~6^2~1 (C++ feature checks: check output for '[Ww]arning', 2017-06-03) accidentally matches `0 Warning(s)` in the output and always thinks a warning exists, thus failing all checks in Visual Studio builds. Fixes: #16942
* Provide and use CM_FALLTHROUGHDaniel Pfeifer2017-06-031-0/+7

* C++ feature checks: check output for '[Ww]arning'Daniel Pfeifer2017-06-031-1/+1
|
* Check C++ features even without CMAKE_CXX_STANDARD for CMake itselfBrad King2017-05-191-13/+16
| | | | | | When using `CMake_NO_CXX_STANDARD` a user may still provide `-std=c++11` or similar flags in `CMAKE_CXX_FLAGS`, so we should still check for the available C++ features.
* cmConfigure: provide macros CM_EQ_DELETE and CM_DISABLE_COPYDaniel Pfeifer2017-04-221-0/+1
|
* Add a feature check to test availability of auto_ptrDaniel Pfeifer2016-09-261-0/+1
|
* Check for availability of unique_ptr and make_unique when building CMakeBrad King2016-09-161-0/+5
| | | | Some code paths may find these useful if available.
* cxx features: add check for nullptrDaniel Pfeifer2016-06-271-0/+1
|
* cxx features: add check for overrideDaniel Pfeifer2016-06-271-0/+1
|
* Use <unordered_set> where availableDaniel Pfeifer2016-06-271-0/+1
|
* Make C++ feature checks extensibleDaniel Pfeifer2016-06-271-0/+36
Turn the feature check for cxx11_unordered_map into a function such that we can use it for other features as well. Drop the 11 suffix, as we may want to check features from other standards.
