* LCC: Add policy CMP0129 regarding interpreting LCC as GNUmakise-homura2021-10-211-0/+3
| | | | | | | | | | Due to MCST LCC compiler identification is now changed to LCC, there should be a way for old projects to still identify it as GNU, as it was before. This commits adds the policy: CMP0129: Compiler id for MCST LCC compilers is now LCC, not GNU. This policy controls such a behavior. OLD behaivior is to treat LCC as GNU, NEW is to treat is as LCC.
* LCC: Add dedicated support for MCST LCC compilermakise-homura2021-10-151-6/+6
| | | | | | | | | | | | | | | | | | | | | 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.
* Tests/CompileOptions: allow CMAKE_BUILD_TYPE=NoneĐoàn Trần Công Danh2021-07-261-0/+4
| | | | | | | | | In the same spirit of commit ce1cadd35a, (Tests/ConfigSources: fix for non main stream CMAKE_BUILD_TYPE, 2021-04-01). Allow distributions' check to pass seemlessly. Issue: #22470

* Tests: Bump CMake minimum required in tests to 2.8.12Chuck Atkins2020-12-231-1/+1
| | | | | | | Since 3.19, CMake generates a deprecation warning when using a minimum version less than 2.8.12. This eliminates those warnings generated during tests, which are typically hidden from the user and developer but are being generated nonetheless.

* Fortran: Add compiler ID/Version generator expressionsAndrew Paprocki2019-01-182-4/+28
| | | | | | | | | | | | Adds `Fortran_COMPILER_ID` and `Fortran_COMPILER_VERSION` generator expression support to match equivalent `C_COMPILER_ID`, `CXX_COMPILER_ID`, `C_COMPILER_VERSION`, and `CXX_COMPILER_VERSION` support. This is very helpful in the case where the C/C++ compiler suite is a different type of compiler from the platform Fortran compiler and projects use generator expressions to assign compiler flags and definitions. (e.g. `GNU` C/C++ and `SunPro` Fortran on Linux)

* target_compile_options: Add syntax to specify shell stringsBrad King2018-03-142-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Options specified via `COMPILE_OPTIONS` and `INTERFACE_COMPILE_OPTIONS` are deduplicated, but individual options can legitimately be duplicated when grouped with other options, e.g. -D A -D B After deduplication that becomes `-D A B`. Therefore we need a way to treat groups of options as units during deduplication. A simple approach is to specify each group as one option, e.g. "-D A" "-D B" However, that conflicts with options that legitimately have spaces. To break this ambiguity, add a `SHELL:` prefix syntax to specify that an option should be parsed like shell command line arguments after deduplication, e.g. "SHELL:-D A" "SHELL:-D B" These will survive deduplication intact, and then be parsed to produce `-D A -D B` on the final command line. Fixes: #15826

* Embarcadero: Check code using CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID.James Johnston2015-12-031-1/+1
| | | | | | | | The CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID variables are set to "Borland" for older versions of the compiler. Newer CodeGear/Embarcadero compilers will have those variables set to "Embarcadero". Search for lines of code referencing both the variable name and Borland to be sure that they also refer to Embarcadero.
* Makefile: Handle '#' in COMPILE_OPTIONS (#15070)Brad King2014-08-122-0/+9
| | | | | | | | | | Teach the Makefile generators to escape '#' characters on the right hand side of variable assignments in flags.make. This is needed for flags like '-Wno-error=#warnings'. Otherwise the make tool treats them as comments and leaves them out of the _FLAGS variable value. Add a case to the CompileOptions test covering '#' in a COMPILE_OPTIONS value, at least on compilers where it is known to be supported.
* Add generator expressions for compiler versions.Stephen Kelly2013-06-282-1/+23
| | | | | New generator expressions allow retrieval of the version per language, as well as equality comparison.
* Escape target flags taken from COMPILE_OPTIONSBrad King2013-06-272-6/+19
| | | | | | | | | | | | Factor appending of individual flags out into an AppendFlagEscape method in cmLocalGenerator and teach it to use EscapeForShell. Update all COMPILE_OPTIONS handling to use AppendFlagEscape. Override the method in the Xcode generator to use its custom escape implementation. Teach the CompileOptions test to add an option that requires escaping everywhere instead of just with the GNU tools.
* Add COMPILE_OPTIONS target property.Stephen Kelly2013-06-023-0/+32
This method reads generator expressions from the COMPILE_OPTIONS target property, as well as INTERFACE_COMPILE_OPTIONS from linked dependents.
