* Allow toolchain suffix without leading dashDan McGregor2023-05-081-1/+1
| | | | | | | | FreeBSD installs both LLVM and gcc with tools named after the major version, in the form "clang<major>", such as "clang16". Detect compilers named this way, and find the related toolchain tools.
* LCC: Add dedicated support for MCST LCC compilermakise-homura2021-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | Divert LCC compiler as a new one, instead of treating it as GNU. Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been passing checks for GNU compilers, so it has been identified as GNU. Now, with intent of seriously upstreaming its support, it has been added as a separate LCC compiler, and its version displays not a supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead of GNU 7.3.0). This commit adds its support for detection, and also converts basically every check like 'is this compiler GNU?' to 'is this compiler GNU or LCC?'. The only places where this check is untouched, is where it regards other platforms where LCC is unavailable (primarily non-Linux), and where it REALLY differs from GNU compiler. Note: this transition may break software that are already ported to Elbrus, but hardly relies that LCC will be detected as GNU; still such software is not known.
* MINGW: Define variable only when targeting Windows platformsBrad King2021-09-171-3/+0
| | | | | | | | | | | | | | | The `MINGW` variable indicates that the compiler targets MinGW, a GNU ABI on Windows. Since commit aff3147917 (Modernize GNU compiler info on Windows, 2009-12-02, v2.8.2~636), we load the `Platform/Windows-GNU` module for compilers targetin MinGW, so set the variable there instead. This is equivalent to `Platform/Windows-MSVC` setting the `MSVC` variable. Also remove `if(MINGW)` checks from the module, which have not been necessary since the enclosed logic was moved to that module. The undocumented `CMAKE_COMPILER_IS_MINGW` internal variable is now unused, so remove it too. Fixes: #22647
* Cygwin: Remove redundant definitions of CYGWIN and UNIX variablesBrad King2021-09-161-2/+0
| | | | | | | | These are set by modules loaded for `CMAKE_SYSTEM_NAME`. We do not need to set them again if the compiler defines `__CYGWIN__`. Also remove the now-unused undocumented `CMAKE_COMPILER_IS_CYGWIN` internal variable.
* DetermineCompiler: Restore identification of MSVC with no INCLUDE or LIBBrad King2021-07-011-1/+2
| | | | | | | Update the change from commit c6aaaf066a (DetermineCompiler: Restore identification of MSVC with no INCLUDE dirs, 2021-06-29, v3.21.0-rc2~6^2) to also work with no `LIB` dirs. Add the `-c` flag to compile an object file without linking.
* DetermineCompiler: Restore identification of MSVC with no INCLUDE dirsBrad King2021-06-291-0/+4
| | | | | | | | | | | | | | | | Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6), our generated compiler id source file contains a preprocessor condition of the form #elif ... && __has_include(...) When MSVC is invoked with no include directories in the `INCLUDE` environment variable or in `-I` flags, its implementation of `__has_include` errors out immediately. This breaks identification of the compiler. Work around the problem by adding a fallback attempt to compile the identification source using a dummy include directory.
* DetermineCompiler: Fix copy-paste error in Intel Compiler detectionGregor Jasny2021-02-171-1/+1
| | | | | Fixes: #21561 Fixes: a90d2a9eed (IntelLLVM: Add support for Intel LLVM-based compilers, 2020-11-02)
* IntelLLVM: Add support for Intel LLVM-based compilersWilliam R. Dieter2021-01-281-2/+3
| | | | | | | | | | | | | | | | | | Using a single ID 'IntelLLVM' for the suite of Intel compilers based on the LLVM backend. The 'IntelLLVM' ID are used for C, C++, and Fortran. Data Parallel C++ will be handled in a separate commit. The C and C++ definitions are based on the Clang definitions. The Intel LLVM-based C and C++ compilers are based on the Clang front end, so existing Clang options are more likely to be a good match than options for the older Intel compilers. Fortran is based on the older Fortran front end with the LLVM backend. It has a similar interface to the older versions, though many options are shared with the C and C++ compilers.

| | | | | | | | | | | | | | | | | | When targeting a platform that supports multiple architectures, Xcode may choose to build all of them in our small compiler id project. Update the regex we use to extract the path to the compiler from the Xcode output to account for this. Fixes: #21425

| |/ | | | | | | | | | | | | | | | | | | | | Capture CMAKE_<LANG>_COMPILER_ARG1 from CMAKE_<LANG>_COMPILER in the same fashion that it is from $ENV{<LANG>}. Since get_filename_component() returns a single string of all the arguments from $ENV{<LANG>}, a single string of arguments will be constructed from the items contained in CMAKE_<LANG>_COMPILER.

* clang: Work around toolchain file use of internal CMake variablesBrad King2019-08-051-0/+16
| | | | | | | | | | | | Since commit d44c0db0b2 (clang: setup correct configuration in gnu mode, 2019-02-20, v3.15.0-rc1~41^2~5) our Clang compiler information modules need the `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` variable that we compute during compiler detection. However, some existing toolchain files set our internal `CMAKE_<LANG>_COMPILER_ID_RUN` variables and block that detection, but do not set the new frontend variant variable. Help them out by setting `CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` anyway. Fixes: #19515, #19539

* Xcode: Detect architecture(s) using ARCHS instead of CURRENT_ARCHBrad King2018-06-181-3/+3
| | | | | | | | | Xcode 10 no longer populates `CURRENT_ARCH` with the current architecture in shell scripts and instead uses `undefined_arch`. Instead we must use `ARCHS`. It lists all architectures separated by spaces. Fixes: #18085
* CMakeFindBinUtils: Improve switch between MSVC- and GNU-like toolsBrad King2017-11-281-1/+1
| | | | | | | | The switch was not considering some languages, such as `ASM`. Instead of memorizing the list of languages in the condition, use a language specified by the includer. Fixes: #17510
* Clang: Diagnose unsupported GNU-like clang targeting MSVC ABIBrad King2017-10-101-0/+1
| | | | | | | | | | The LLVM/Clang installer on Windows provides a `LLVM/bin` directory containing `clang.exe` and `clang++.exe` command-line tools that have a GNU-like command-line but target the MSVC ABI (instead of MinGW). We do not support this combination, so diagnose and reject it explicitly. Tell users what to do to use the `clang-cl.exe` tool instead. Issue: #16439
* Add a CMAKE_<LANG>_COMPILER_ARCHITECTURE_ID variableNorbert Lange2017-06-291-0/+7
| | | | | | | | | | Compilers such as MSVC and IAR may have variants that target different architectures. We have been using a `MSVC_<LANG>_ARCHITECTURE_ID` variable to hold this information for MSVC. Add an alternative with a more general name (later we can port MSVC to it too). This additional information may be needed to generate proper invocations of the compiler based on its architecture variant.
* Xcode: Detect CURRENT_ARCH for use by generatorBrad King2017-03-311-0/+5
| | | | | | | During compiler identification, extract the Xcode `CURRENT_ARCH` value and save it for later use by the Xcode generator in an internal compiler information variable. This will be useful to know the locations of object files when only one architecture is built.

* Simplify CMake per-source license noticesBrad King2016-09-271-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

* Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596)Brad King2015-09-181-1/+0
| | | | | | | | Move detection over to the compiler id logic where we have already constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS. Pass the flags when we execute "cl" with "/showIncludes". Also pass "/c" because we only need to compile, not link. Check the compiler process exit code before trusting its output.

* | CMakeDetermineCompilerId: Optionally try some flags before no flagsBrad King2015-06-181-0/+1
|/ | | | | | | | Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the compiler id using some given flags before trying to detect it with no special flags. This will be useful for Fortran detection to distinguish some compilers that use the preprocessors of others but have no macro of their own by getting verbose output.
* Avoid if() quoted auto-dereferenceBen Boeckel2014-10-201-4/+4
| | | | | | | When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly dereference or quote the variable. We want if() to auto-dereference the variable and not its value. Also replace MATCHES with STREQUAL where equivalent.

| | | | | | | | | | | | | | | | | | Since commit v3.0.0-rc1~342^2~2 (Add compiler target compile options, 2013-05-19) we use CMAKE_<LANG>_COMPILER_TARGET as the binutils prefix when cross-compiling with Clang. Fix the implementation to use the compiler target as the prefix only when it is set. Otherwise toolchain files not using CMAKE_<LANG>_COMPILER_TARGET cause the logic to use a prefix of just "-" and of course cannot find "-ar" or "-ld".
