* compilers: convert method to get assert control to a booleanDylan Baker2023-04-211-5/+10
| | | | | | | | C like compilers only off `-DNDEBUG` to disable asserts. This is not a universal paradigm however. Rust, for example has an argument that takes a boolean. To better represent this, we allow passing a `disable` boolean. `disable` was chosen rather than `enable` because it allowed all existing logic to be left in place
* intro: add more details to generated json filesCharles Brunet2023-04-201-1/+1
| | | | | | | | | | | | | | This will help with the writing of tools to generate VisualStudio project and solution files, and possibly for other IDEs as well. - Used compilers a about `host`, `build` and `target` machines arere listed in `intro-compilers.json` - Informations lister in `intro-machines.json` - `intro-dependencies.json` now includes internal dependencies, and relations between dependencies. - `intro-targets.json` now includes dependencies, `vs_module_defs`, `win_subsystem`, and linker parameters.

* Add Compiler.cached_run()Andres Freund2023-02-271-1/+29
| | | | | | | | Caching Compiler.run() seems likely to cause problems, but some users, like .sizeof(), we know enough about the program run to make it safe. This commit just adds the Compiler.cached_run(), a subsequent commit makes use of it.

* compilers: Make sure to not use ccache in compiler checksXavier Claessens2022-10-251-3/+4
| | | | | | | | | | ccache was used in all command lines but disabled using CCACHE_DISABLE in Compiler.compile() method. Wrapping invokations still has a cost, especially on Windows. With sccache things are even worse because CCACHE_DISABLE was not respected at all, making configure *extremely* slow on Windows when sccache is installed.
* Compilers: Keep ccache and exelist separatedXavier Claessens2022-10-251-2/+2
| | | | | Only combine them in the Compiler base class, this will make easier to run compiler without ccache.

* compilers: Add optimization=plain optionJan Tojnar2022-10-091-2/+4
| | | | | | | | | | | | | | https://github.com/mesonbuild/meson/pull/9287 changed the `optimization=0` to pass `-O0` to the compiler. This change is reasonable by itself but unfortunately, it breaks `buildtype=plain`, which promises that ā€œno extra build flags are usedā€. `buildtype=plain` is important for distros like NixOS, which manage compiler flags for optimization and hardening themselves. Letā€™s introduce a new optimization level that does nothing and set it as the default for `buildtype=plain`.
* compilers: Cleanup a bit languages/suffixes listsXavier Claessens2022-09-271-18/+22
| | | | | Use set where order does not matter, fix is_source() to really mean only source suffixes.
* compilers: drop some useless info from CompileResultEli Schwartz2022-09-091-5/+2
| | | | text_mode was never set, nor used, and pid was set but never used.
* compilers: fix regression in logging cached compile commandsEli Schwartz2022-09-091-4/+3
| | | | | | | | | | | | | In commit d326c87fe22507b8c25078a7cd7ed88499ba7dc1 we added a special holder object for cached compilation results, with some broken attributes: - "command", that was never set, but used to print the log - "args", that was set to some, but not all, of the information a fresh compilation would log, but never used Remove the useless args attribute, call it command, and use it properly.
* env2mfile: reuse logical lists of interesting facts from meson itselfEli Schwartz2022-09-011-0/+1
| | | | | | | | | Meson internally knows about many languages and tools, and *FLAGS variables, and which languages to use them for. Instead of duplicating this logic, import it from mesonbuild.* This logic was originally standalone, but now that it is merged into the Meson tree we can have a single source of truth.
* fix linker regression for compilers that don't accept LDFLAGS directlyEli Schwartz2022-08-241-1/+5
| | | | | | e.g. ldc -- the compiler needs to process args before consuming them. Fixes #10693

* compilers: Add support for stand-alone leak sanitizerMarco Trevisan (TreviƱo)2022-06-061-1/+1
| | | | | | | | | Leak sanitizer can be enabled without the whole AddressSanitizer, this can be done by passing -fsanitize=leak as documented at [1]. Meson doesn't support this, so add support for it. [1] https://clang.llvm.org/docs/LeakSanitizer.html
* compiler: Add missing needs_static_linker to base Compiler classDylan Baker2022-06-011-0/+3
|
* linkers: Add support for mold linkerFini Jastrow2022-04-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | [why] Support for the relatively new mold linker is missing. If someone wants to use mold as linker `LDFLAGS="-B/path/to/mold"` has to be added instead of the usual `CC_LD=mold meson ...` or `CXX_LD=mold meson ...`. [how] Allow `mold' as linker for clang and newer GCC versions (that versions that have support). The error message can be a bit off, because it is generic for all GNU like compilers, but I guess that is ok. (i.e. 'mold' is not listed as possible linker, even if it would be possible for the given compiler.) [note] GCC Version 12.0.1 is not sufficient to say `mold` is supported. The expected release with support will be 12.1.0. On the other hand people that use the un-released 12.0.1 will probably have built it from trunk. Allowing 12.0.1 is helping bleeding edge developers to use mold in Meson already now. Fixes: #9072 Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
* OptionOverrideProxy: Make it immutable to avoid copiesXavier Claessens2022-03-221-2/+2
| | | | | | It is always used as an immutable view so there is no point in doing copies. However, mypy insist it must implement the same APIs as Dict[OptionKey, UserOption[Any]] so keep faking it.

* fix type annotations for compiler toolchain rpathsEli Schwartz2021-12-301-1/+1
| | | | | We pass around a tuple of rpaths, because rpaths *can* be more than one. But all the annotations said it would be a str instead.
* migrate python 3.5 compatible superclass variable annotations to 3.6Eli Schwartz2021-11-011-5/+3
| | | | | As we now require python 3.6, we can declare their types without initializing them.

|\ | | | | Use appropriate compiler for the source file for "links" tests with file argument
| * interpreter: detect and pass compiler to be used for linker testsPaolo Bonzini2021-09-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Allow using the links method to test that the C++ driver (e.g. g++) can be used to link C objects. One usecase is that the C compiler's libsanitizer might not be compatible with the one included by the C++ driver. This is theoretically backwards-incompatible, but it should be treated as a bugfix in my opinion. There is no way in Meson to compile a .c file with the C++ driver as part of a build target, therefore there would be no reason to do something like meson.get_compiler(meson.get_compiler('cpp').links(files('main.c')). Fixes: #7703
| * compilers: allow link tests to use objects from a different compilerPaolo Bonzini2021-09-071-2/+12
| | | | | | | | | | | | | | | | | | | | | | In some cases, link tests would like to use objects provided by a compiler for a different language, for example linking a C object file with a C++ compiler. This kind of scenario is what link_language is for, but it is impossible to test that it works with a linker test. This patch implements the required support in the Compiler class. The source code compiler is passed to the Compiler.links method as an argument.
| * compilers: do accept None in Compiler.compile extra_argsPaolo Bonzini2021-09-071-1/+2
| | | | | | | | The type information allows it, but it is not actually handled.

* | compilers: Add default search path stdlib_only_link_flagsDylan Baker2021-09-251-1/+1
| | | | | | | | | | | | | | | | | | This should be done in all cases of language_stdlib_only_link_flags, but I don't have access to all of the compilers to test it. This is required in cases where object files created by gfortran are linked using another compiler with a differen default search path, such as gfortran and clang together.

* Clang should error for all implicit function checks (#9165)Dylan Baker2021-09-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | * compilers: improve docstring to `get_compiler_check_args()` There was an incomplete list, which wasn't useful as it now takes an enum anyway. Also add a new entry to the list of reasons to use this function. * clang: Add -Werror=implicit-function-declarations to check_args Unlike GCC, clang warns but doesn't error when an implicit function declaration happens. This means in checks like `compiler.has_header_symbol('string.h', 'strlcat')` (on Linux, at least) that GCC will fail, as there is no such function; clang will emit a warning, but since it exists with a 0 status Meson interprets that as success. To fix this, add `-Werror=implicit-function-declarations` to clang's check arguments. There seems to be something specific about functions that _may_ exist in a header on a given system, as `cc.has_header_symbol('string.h', 'foobar')` will return false with clang, but `strlcat` will return true, even though it's not defined. It is however, defined in some OSes, like Solaris and the BSDs. Fixes #9140
* compilers: Add get_no_warn_args to the base Compiler classDylan Baker2021-08-201-0/+4
| | | | Because it should be defined there.
* compilers/compilers: Fix some potential issues spotted by pyrightDylan Baker2021-08-161-2/+4
| | | | | | | There are two changes here, one is to remove an `elif` that is effectively an `else`, that helps the type checker and provides a small speedup potentially. The second is a potentially unbound variable, that currently isn't hit, but very much could be.
* compilers: Fix extra_args parameterDylan Baker2021-08-161-13/+15
| | | | | which can also be a callable taking a CompileChekcMode as an argumetn and returning a list of strings.
* compilers: Fix annotations for run and cached_compileDylan Baker2021-08-161-5/+5
| | | | | Which absolutely should accept `str | File`, but the annotations claim that only strings are accepted.

* linkers: remove is_shared_module argument to get_soname_argsPaolo Bonzini2021-07-141-3/+2
