* NAG: Use -PIC for Fortran position-independent executable codeNeil Carlson2016-08-091-0/+1
| | | | | | | | | The Numerical Algorithms Group (NAG) Fortran compiler documents -PIC for position-independent code and does not have a separate option for PIE. We added `-PIC` for PIC in commit v2.8.11~174^2 (NAG: Use -PIC for Fortran position-independent code, 2013-02-18). Follow up for PIE. Closes: #16236

| |/ | | | | | | | | | | | | | | | | | | | | Without extensions, functions like `strdup` are not available since they are actually controlled by feature flags such as _SVID_SOURCE and _BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are set, so the functions are not declared properly leading to compile errors. Reported-by: Adam J. Stewart <ajstewart426@gmail.com> Closes: #16226

Change our convention for setting these variables from: set(CMAKE_C_FLAGS_INIT "...") to string(APPEND CMAKE_C_FLAGS_INIT " ...") so that any value previously set by a toolchain file will be used. Automate the conversion with: sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \ Modules/Compiler/*.cmake Modules/Platform/*.cmake and follow up with some manual fixes (e.g. to cases that already meant to append). Also revert the automated changes to contexts that are not protected from running multiple times.
* | Intel: Do not use GNU-like flags on WindowsBrad King2016-07-055-24/+54
|/ | | | | | | | | | | Refactor options out of `Modules/Compiler/Intel-{ASM,C,CXX,Fortran}.cmake` into a common helper in `Modules/Compiler/Intel.cmake`. Condition them to be used only on non-Windows hosts where the Intel compiler is GNU-like instead of MSVC-like. Previously this worked only because the options were later overridden by `Modules/Platform/Windows-Intel*.cmake`, but it is cleaner to not set the options in the first place.

* Apple: Enable -isystem for GNU Compiler >= 4 (#15953)Gregor Jasny2016-02-071-1/+1
| | | | | | | | Due to #4662 -isystem support was disabled for all GNU Compilers on Apple platforms. But the change was probably a just work around for a broken compiler on Tiger (see 10837#c27206). So we tighten the condition to only kick in for GCC versions earlier than 4. That should ensure sane behavior for Xcode 3.2 and later.
* IAR: Add support for using this compiler with the Ninja generatorJuhani Simola2016-02-032-1/+5

| | | | | | | When parsing implicit include dirs, link dirs, and link libs, all arguments are resolved to absolute paths instead of relative paths. This is correct for link and include directories but link libraries should only include the library name, not it's path.

| * Cray: Refactor the Cray platform files to use compiler wrapper checksChuck Atkins2015-12-0916-0/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | This is an extensive refactoring of the Cray compiler wrapper usage. Using the new compiler wrapper checks, the CrayPrgEnv info files have been moved from Platform/ to Compiler/. The adjusted naming convention allows the compiler-wrapper information files to be loaded for both the CrayLinuxEnvironment platform when cross-compiling and the Linux platform if building natively on the Cray compute nodes. It also creates a separation of common arguments for compiler id and language information used to perform the appropriate introspection of implicit arguments and libraries used by the compiler wrappers based on the loaded module environment.
* | Embarcadero: Fix erroneous interpretation of __CODEGEARC_VERSION__.James Johnston2015-12-031-1/+1
|/ | | | | | | | | | | | | As per the following link: http://docwiki.embarcadero.com/RADStudio/Seattle/en/Example_of_CODEGEARC_VERSION_Macro The major/minor versions must be decoded as a hex string, while the patch version must be decoded as a normal decimal string. As an example, C++ Builder XE 8.1's bcc32.exe sets this macro to 0x070189C9. The file version of bcc32.exe is 7.1.5570.35273. Therefore, the correct interpretation to COMPILER_VERSION would be 7.1.35273.

| * Project: Guess default standard dialect if compiler was forced (#15852)Brad King2015-11-197-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to commit v3.4.0-rc1~71^2 (Project: Determine default language dialect for the compiler, 2015-09-15) we always guessed the default language standard dialect based on the compiler version. This was not reliable so that commit switched to computing the default language standard dialect while detecting the compiler id. When a toolchain file uses CMakeForceCompiler to set the compiler id then the detection does not occur. Therefore commit v3.4.0-rc1~54^2 (Project: Don't require computed default dialect if compiler was forced, 2015-09-22) made the lack of detection an error only if the compiler was not forced. However, this means that projects using CMakeForceCompiler no longer even get the guess that we had before so <LANG>_COMPILER does not work. Due to the sophistication of CMake's compiler detection logic projects should be ported away from using CMakeForceCompiler. In the meantime, restore a guess of the default language standard dialect when the compiler is forced.

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.

* Project: Don't require computed default dialect if compiler was forced.Stephen Kelly2015-09-227-21/+35
| | | | | | | | | | | | | | | | Commit 7235334a (Project: Determine default language dialect for the compiler., 2015-09-15) introduced a mechanism to determine the default dialect used for the running compiler. If conditions in the <CompilerId>-<Lang>.cmake file are such that compile features for that version of the compiler should be supported, the _DEFAULT_STANDARD is set to the computed value. However, the CMakeForceCompiler module allows users to bypass execution of the compiler by CMake. In that case, do not set the _DEFAULT_STANDARD variable at all, which effectively disables the compile-features where the module is used. No compile features have ever been recorded where the module is used so no functionality is lost.
* Project: Determine default language dialect for the compiler.Stephen Kelly2015-09-187-15/+34
