* Reinstate "compilers/c: Fix allow undefined link arg for PE/COFF"Martin Storsjö2018-12-091-0/+3
| | | | | This reinstates 2256e6314b610b8f6645d0c5384536001ddeccf9, which was lost in refactoring in 9f9cfd21396db5cd5eb1711916c8b0c6e433c702.
* Deduplicate export-dynamic and pthread. Closes #4567.Jussi Pakkanen2018-12-061-1/+15

* compilers: Move get_allow_undefined_link_args to CompilerDylan Baker2018-11-151-0/+14
| | | | | | | This allows each implementation (gnu-like) and msvc to be implemented in their respective classes rather than through an if tree in the CCompiler class. This is cleaner abstraction and allows us to clean up the Fortran compiler, which was calling CCompiler bound methods without an instance.
* compilers: ICC should error when an unknown __attribute__ is testedDylan Baker2018-11-151-0/+1
|
* compilers: Enable PGO for ICCDylan Baker2018-11-151-5/+24
| | | | | | | | ICC doesn't use the same -fprofile-generate/-fprofile-use that GCC and Clang use, instead it has -prof-gen and -prof-use. I've gone ahead and added the threadsafe option to -prof-gen, as meson currently doesn't have a way to specify that level of granularity and GCC and Clang's profiles are threadsafe.
* compilers: fix compiler.compile for Intel CompilersDylan Baker2018-11-151-4/+15
| | | | | has_arguments is the wrong thing to fix, since all checks that require compiler options are based on compiles, it's the right thing to modify.
* compilers: Fix the set of features that ICC exposesDylan Baker2018-11-151-1/+8
|
* compilers: Use keyword only arguments for compiler interfacesDylan Baker2018-11-131-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | Because we need to inherit them in some cases, and python's keyword-or-positional arguments make this really painful, especially with inheritance. They do this in two ways: 1) If you want to intercept the arguments you need to check for both a keyword and a positional argument, because you could get either. Then you need to make sure that you only pass one of those down to the next layer. 2) After you do that, if the layer below you decides to do the same thing, but uses the other form (you used keyword by the lower level uses positional or vice versa), then you'll get a TypeError since two layers down got the argument as both a positional and a keyword. All of this is bad. Fortunately python 3.x provides a mechanism to solve this, keyword only arguments. These arguments cannot be based positionally, the interpreter will give us an error in that case. I have made a best effort to do this correctly, and I've verified it with GCC, Clang, ICC, and MSVC, but there are other compilers like Arm and Elbrus that I don't have access to.

* Add new compiler.get_argument_syntax methodDylan Baker2018-11-031-0/+14
| | | | | | | | | | | Some compilers try very had to pretend they're another compiler (ICC pretends to be GCC and Linux and MacOS, and MSVC on windows), Clang behaves much like GCC, but now also has clang-cl, which behaves like MSVC. This method provides an easy way to determine whether testing for MSVC like arguments `/w1234` or gcc like arguments `-Wfoo` are likely to succeed, without having to check for dozens of compilers and the host operating system, (as you would otherwise have to do with ICC).
* Hoist gen_vs_module_defs_args from Gnu to GnuLike.Josh Gao2018-10-301-10/+10
| | | | | | Support vs_module_defs when cross-compiling to Windows with clang. Fixes #4434.
* Generalize gnulike-targeting-windows checks.Josh Gao2018-10-301-2/+2
| | | | | | | | | Replace several checks against GCC_MINGW or (GCC_MINGW, GCC_CYGWIN) with is_windows_compiler instead, so that clang and other gcc-like compilers using MinGW work appropriately with vs_module_defs, c_winlibs, and cpp_winlibs. Fixes #4434.
* get_base_compile_args: Add -fprofile-correction to -fprofile-useJan Alexander Steffens (heftig)2018-10-281-2/+2
| | | | | | | | | This allows using the imperfect profiles generated by multithreaded programs. Without the argument, GCC fails to load them. Clang just ignores the argument AFAICT. Fixes https://github.com/mesonbuild/meson/issues/2159

| | | | | On Android executables must be position independent, many distributions enable it by default too for security reasons.
* Use relative build-tree RPATHs on macOSDavid Seifert2018-10-141-26/+32
| | | | | | | | | | | | * This helps with reproducibility on macOS in the same way `$ORIGIN` improves reproducibility on Linux-like systems. * This makes the build-tree more resilient to users injecting rpaths via `LDFLAGS`. Currently Meson on macOS crashes when a build-tree rpath and a user-provided `-Wl,-rpath` in LDFLAGS collide, leading to `install_name_tool` failures. While this still does not solve the root cause, it makes the occurrence much less likely, as users will generally pass absolute `-Wl,-rpath` arguments into Meson.
* Adding "compiler_type" flag to ARM compilers.Mohammed Amer Khalidi2018-10-071-3/+7
|
* msvc: Don't use /O3 with MSVCMartin Storsjö2018-10-011-1/+1
| | | | | MSVC doesn't support that option, and warns about ignoring an unknown option.
* linker flags --as-needed and --no-undefined aren't meaningful for PEJon Turney2018-09-231-2/+4
| | | | | | | | | | | --as-needed controls ELF-specific functionality (the emission of DT_NEEDED tags) --no-undefined is effectively always on for PE/COFF, as the linkage model always requires symbols to be defined binutils ld silently ignores these flags for PE targets, but lld warns that it's ignoring them, so just don't bother emitting them for PE targets.

* Use enum instead of `int` for compiler variantsDavid Seifert2018-09-161-68/+69
| | | | | | | | * Enums are strongly typed and make the whole `gcc_type`/`clang_type`/`icc_type` distinction redundant. * Enums also allow extending via member functions, which makes the code more generalisable.
* Sprinkle functools.lru_cache() in a few more placesNirbheek Chauhan2018-09-111-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This improves the backend generation time for gst-build from 7.4s to 6.6s.

* Add method to check for C/C++ function attributesDylan Baker2018-09-071-0/+4
| | | | | | | | | | | | | | | It's fairly common on Linux and *BSD platforms to check for these attributes existence, so it makes sense to me to have this checking build into meson itself. Autotools also has a builtin for handling these, and by building them in we can short circuit cases that we know that these don't exist (MSVC). Additionally this adds support for two common MSVC __declspec attributes, dllimport and dllexport. This implements the declspec version (even though GCC has an __attribute__ version that both it and clang support), since GCC and Clang support the MSVC version as well. Thus it seems reasonable to assume that most projects will use the __declspec version over teh __attribute__ version.
* Improve support for macOS dylib versioningNirbheek Chauhan2018-08-291-15/+15
| | | | | | | | | | | | | | We now use the soversion to set compatibility_version and current_version by default. This is the only sane thing we can do by default because of the restrictions on the values that can be used for compatibility and current version. Users can override this value with the `darwin_versions:` kwarg, which can be a single value or a two-element list of values. The first one is the compatibility version and the second is the current version. Fixes https://github.com/mesonbuild/meson/issues/3555 Fixes https://github.com/mesonbuild/meson/issues/1451
* Deduplicate build-tree RPATHs on macOSDavid Seifert2018-08-281-2/+4
| | | | | | | | | | * Currently, RPATHs coming from dependencies and `build_rpath` provided by the user might contain the same path. Apple's `install_name` tool is allergic to providing the same argument twice when removing RPATHs: error: install_name_tool: "-delete_rpath /usr/lib" specified more than once
* CompilerArgs: -Wl,-lfoo is also a valid way to pass a libraryNirbheek Chauhan2018-08-281-2/+2
| | | | | | | | | Treat it the same as -lfoo by deduping and adding to --start/end-group Reported at https://gitlab.gnome.org/GNOME/glib/issues/1496 We don't do any advanced transformation for MSVC or de-dup because this is a very rare syntax.

| | | | | | | | Dub enables inlining by default for release builds, so meson should do it as well.
* | CompilerArgs: Allow calling to_native() multiple timesNirbheek Chauhan2018-08-231-5/+9
| | | | | | | | | | | | | | | | | | Add a keyword argument to to_native() to operate on a copy so that we can call it multiple times instead of modifying the original compiler args while iterating. This is used in the unit test, and might be used in Meson at some point too.
* | compilers: Handle dupes in the --start/end-group logicOle André Vadla RavnÄs2018-08-231-3/+4
| | | | | | | | | | The index calculated through `self.index()` may find the same flag earlier in the list and end up putting `--end-group` in the wrong spot.
* | compilers: Reduce sizes of MSVC linked binariesOle André Vadla RavnÄs2018-08-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | - For optimization=s add /O1: Use Maximum Optimization (Favor Size), and remove /Os as it's implied by /O1. - Because we add /O1, this implies /Gy, i.e. Function-Level Linking, so unused code can be omitted. - Add /Gw: Optimize Global Data, so unused data can be omitted. With buildtype=minsize on x86 this reduces the size of a statically linked Vala compiler binary from 5 MB down to just 1.87 MB.
* | find_library: Use _build_wrapper to get library dirsBruce Richardson2018-08-221-10/+14
| | | | | | | | | | | | | | | | | | | | This means that we will take into account all the flags set in the cross file when fetching the list of library dirs, which means we won't incorrectly look for 64-bit libraries when building for 32-bit.
