* Place language standard flags just after CMAKE_<LANG>_FLAGSBrad King2022-11-181-0/+22
| | | | | | | | | | | | | | | | Previously we added the language standard flag near the end of all options, even after those added by `add_compile_options` and friends. However, on some compilers such as MSVC, the `-std` flag may reset defaults for flags that precede it on the command line. Move the language standard flag to before all other flags that CMake adds for other abstractions, and before those added by `add_compile_options`. `CMAKE_<LANG>_FLAGS` should still precede the language flags though, because they are meant to be treated as language-wide modifications to the compiler defaults, similar to `$CC $CFLAGS`. Fixes: #23860 Fixes: #24170
* Help: Document explicitly that 'cxx_std_##' features may not add a flagBrad King2022-03-071-0/+2
| | | | | This is commonly reported incorrectly as a bug, so call out this behavior explicitly in the documentation.
* Help: Better explain CMAKE_<LANG>_EXTENSIONS_DEFAULTRaul Tambre2021-11-021-3/+3
| | | | | | | | | | | | | | | | Explain that this represents the compiler's default and mustn't be modified by the user. Clarify when it's used as the default. Additionally: * Add a reference to it in cmake-compile-features in text explaining the feature. * Add explanations for the default initialization by `CMAKE_<LANG>_EXTENSIONS_DEFAULT` to all `<LANG>_EXTENSIONS` pages and references to CMP0128. * Slightly reduce the wordiness of the default initialization explanations by removing an unnecessary "it is". Fixes #22828.
* cmStandardLevelResolver: Avoid unnecessary flags, fix unset level logicRaul Tambre2021-09-291-6/+5
| | | | | | | | | | | | | | | | | | The changes are part of CMP0128. When the standard level is unset: * Flags are added if extension mode doesn't match the compiler's default. Previously logic only worked if LANG_EXTENSIONS was ON. Fixes #22224. * The full flag is used. Previously CMAKE_LANG_EXTENSION_COMPILE_OPTION was used. This was only supported for IAR. Otherwise: * Avoid adding flags if not necessary per the detected compiler defaults. * Fixed check for when the requested standard is older. It now matches the nearby comments. I reworded the fallback comment as its logic was a bit difficult to wrap my head around.

| * Help: Do not recommend WCDH in cmake-compile-features(7)Brad King2021-04-231-114/+16
| | | | | | | | | | | | | | | | | | Since commit da7ad7997e (WriteCompilerDetectionHeader: Add policy to remove module, 2020-12-04, v3.20.0-rc1~350^2), the WCDH module is deprecated. Update the `cmake-compile-features(7)` manual section that previously recommended WCDH to make such detection the project's responsibility instead. Move the old content of the section over to the WCDH module to preserve it.

* Compiler/TI: Add std options for C++98Josef Angstenberger2020-09-201-1/+1
| | | | | | | | The TI compiler does not support C++98, only C++03 (based on manual of current version). This change sets the C++98 option to C++03 based on the fact that it is done this way for the SunPro compiler already.

* Features: Record features for Intel Compiler on WindowsBrad King2016-10-271-1/+1
| | | | | | | | | | | | | Since this compiler always defines `__cplusplus` to `1` we need to use `_MSC_VER`, `__INTEL_CXX11_MODE__`, and the feature test macro named `__cpp_aggregate_nsdmi` to detect C++11 and C++14 modes. With no `-Qstd=` flag this compiler defaults to C++98 plus a subset of C++11/C++14 features needed to be compatible with MSVC. We pretend it is plain C++98 and add a `-Qstd=` flag whenever needed for C++11 or above features even if they would happen to be available in MSVC-mode. Closes: #16384
* Features: Specify minimum version Intel C++ 12.1Robert Maynard2016-04-281-0/+1
| | | | | | Versions below 12.1 do not provide enough information to properly detect if compiling with c++98 or c++0x enabled so remove them from the supported list.
* Revert topic 'compiler-features-solaris'Brad King2015-10-081-1/+1
| | | | | | | | Revert commit v3.4.0-rc1~10^2~2 (Features: Disable support for Oracle SolarisStudio on non-Linux, 2015-09-29) and two follow-up commits. The support of compile features and language standards on Orcale SolarisStudio needs more investigation so for CMake 3.4 we should just act as 3.3 did.
* Features: Disable support for Oracle SolarisStudio on non-LinuxBrad King2015-09-291-1/+1
| | | | | | On SunOS the -std=c++11 flag must be used for linking as well as compiling. Until we implement support for this we cannot support the CXX_STANDARD property except on Linux (where it was tested).
* Help: Fix typo in cmake-compile-features(7) manual (#15594)Erik Sjölund2015-05-291-1/+1
| | | | | | | target_link_libraries() is being used in the example code but target_include_directories() was probably meant to be used. The sentence that starts with "Consuming code then" indicates that the example is about using the appropriate include directory.

* WCDH: Remove noise from generated defines.Stephen Kelly2014-06-131-5/+5
| | | | | | The DECL part is redundant, and the language part is not needed. The source language and context already determines the language, so there is no need to repeat it in the define name.
* Features: Enable compiler extensions by default.Stephen Kelly2014-05-311-14/+11
