* Features: Ensure appropriate return value from feature test macros.Stephen Kelly2015-01-156-12/+5
| | | | | | | GNU-CXX already has complex logic and sets the _result to 0 before tests which may set it to something else. Change the other modules to be consistent with that.

* Oracle/Sun: Fix Fortran preprocessor rule generationBrad King2014-12-231-1/+1
| | | | | | | | | The SunPro Fortran compiler uses "-F" instead of "-E" to request preprocessing. The output does not go to stdout so use "-o" to specify the output file. This fixes the guess originally made by commit b6b37e30 (Makefile: Add assembly and preprocessed targets for Fortran, 2014-11-05).

| | | | | | | | | | | | | | | | | | The __STDC_VERSION__ macro may be defined or not depending on the implementation dialect of C. Test that it is defined before testing its value. The CXX tests do not need such a change because they define __cplusplus in all dialects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang 3.4 uses C99 by default, and Clang 3.6 uses C11 by default: http://thread.gmane.org/gmane.comp.compilers.clang.devel/39379 GNU 4.9 uses C90 by default, and GNU 5.0 uses C11 by default: https://gcc.gnu.org/gcc-5/changes.html Test that the default compiler settings result in the expected dialect macros being defined for both C and CXX.

|\ \ | |/ | | | | | | ded30405 Features: Don't record for AppleClang
| * Features: Don't record for AppleClangStephen Kelly2014-11-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Features are currently recorded accidentally for all versions of AppleClang > 3.4 (I have no idea how that relates to upstream Clang). Presumably that version has the features which are accidentally recorded, but in the future features will be recorded initially for only AppleClang >= 5.1, which would appear as a feature regression. Commit v3.1.0-rc1~635^2~11 (Don't load Clang-CXX from AppleClang-CXX., 2013-11-11) ajusted the logic for the CXX language. Make a similar change for the C language.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit v3.0.0-rc1~111^2 (QNX: Introduce QCC compiler id for that QNX platform compiler., 2014-01-20) split handling of the QNX QCC compiler into a separate compiler-id. That refactoring results in the QCC compiler not using the CMake-compiler-id "GNU", which means that the __compiler_gnu macro is no longer executed for it. Add Compiler/QCC*.cmake modules to define and call the __compiler_qcc macro and teach it to call __compiler_gnu internally. Remove the corresponding pieces from the Platform/QNX*.cmake modules. It is also necessary to change the language conditional to dereference the lang macro parameter, which is another bug introduced by the same commit. The extra -lang-c++ flag is only necessary when the CXX compiler is specified as 'qcc' instead of 'QCC' in the toolchain file, which is why this bug was not noticed before. The flag is also necessary in that case when linking in order to find the appropriate standard libraries. The flag was not previously added when linking executables, so linking failed even with CMake 2.8.12 with the lower-case compiler-id. Co-Author: Brad King <brad.king@kitware.com>
