2021-03-04mass rewrite of string formatting to use f-strings everywhereEli Schwartz1-18/+18
performed by running "pyupgrade --py36-plus" and committing the results
2021-03-04various python neatness cleanupsEli Schwartz1-3/+3
All changes were created by running "pyupgrade --py3-only --keep-percent-format" and committing the results. I have not touched string formatting for now. - use set literals - simplify .format() parameter naming - remove __future__ - remove default "r" mode for open() - use OSError rather than compatibility aliases - remove stray parentheses in function(generator) scopes
2021-02-14aix: avoid -bsvr4 flagPeter Harris1-9/+22
The svr4 linker flag causes issues, especially when compiling c++. Replace '-z' options with the equivalent non-svr4 flags. When using -blibpath, we must be careful to include the default system library path, or the resulting executables will not be able to find libc. This patch was suggested by @andreaskem in #7581.
2021-01-11move handling of CFLAGS and friends to environmentDylan Baker1-16/+1
This has a bunch of nice features. It obviously centralizes everything, which is nice. It also means that env is only re-read at `meson --wipe`, not `meson --reconfigure`. And it's going to allow more cleanups.
2021-01-11import MachineChoice from mesonlibDylan Baker1-1/+1
there are a couple of places importing it from envconfig, which is not correct. It's defined in mesonlib, and then imported into envconfig.

2020-12-15Fix the subsystem options for lld in mingw modeMartin Storsjö1-15/+12
lld in gnu like mode (e.g. for mingw) needs these options in the same for as gnu ld, thus remove the lld specific code bit and move the code for gnu like options into GnuLikeDynamicLinkerMixin. This unbreaks linking with lld for mingw targets after 2fb4d1f7512a4ec125883fd65115ab33a5b06b6f.

2020-10-04linkers: Drop -pie on macOSRoman Bolshakov1-1/+1
Projects that specify b_pie=true clutter build logs with the warning: clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument] No option is needed to produce PIE binaries because ld64 is making PIE executables on 10.7 and above by default, as documented in ld(1).

2020-09-24compilers: Tell mypy that the compiler mixins are just thatDylan Baker1-0/+1
We do this by making the mixins inherit the Compiler class only when mypy is examining the code (using some clever inheritance shenanigans). This caught a bunch of issues, and also lets us delete a ton of code.
2020-09-18Some fixes for CompCertSebastian Meyer1-2/+2
1. Like with gcc's `ld`, also use the `group_start` code to create a `--start-group`/`--end-group` 2. xc16 tricked into believing the 'link_whole' was about `--*-group`, but it should use gcc's `--whole-archive` instead. 3. Not clear what the get_lib_prefix should really do, but for picolibc it seems I want just `''`. The problem with picolibc was that the `-l` would be prefixed to a lib like `picolib/libm/libm.a`. Though of course the `-l` would be necessary for just a plain `m` (that's what I assumed this would be used for). I think this might need some clarification from the meson devs ;-)
2020-09-16linkers: fully type annotate and fix mypy issuesDylan Baker1-6/+24
This makes GnuDynamicLinker not suitable for instantiation, so the tests need to be changed to use the BFD class.
2020-09-16linkers/compilers: Move an emscripten method to the compilerDylan Baker1-7/+0
This needed an attribute the linker doesn't have.
2020-09-16linkers: Make id a class variable for DynamicLinkersDylan Baker1-33/+48
Originally I had this idea that you'd be able to pass the id in to be able to deduplicate some cases (like ld.gold and ld.bfd). That went away because it ended up being really un-dry, but this id per instance remained. Getting rid of it allows us to get rid of a bunch of otherwise useless super calls, which makes adding type annotations easier.
2020-09-16linkers: Fix argument errorDylan Baker1-1/+1
The name of the argument passed was not the name of the argument used.
2020-09-15Add support for the CompCert C CompilerSebastian Meyer1-0/+53
* Add preliminary support for the CompCert C Compiler The intention is to use this with the picolibc, so some GCC flags are automatically filtered. Since CompCert uses GCC is for linking, those GCC-linker flags which are used by picolibc, are automatically prefixed with '-WUl', so that they're passed to GCC.

Without the -Xany flag, the ar command will complain when an .o file is compiled for the non-default bit width. This change is necessary to allow 64-bit builds via a native (or cross) file.

2020-08-02Make meson recognize the Qualcomm LLVM toolchainAntony Chan1-0/+6
Meson calls `path/to/clang++ --version` to guess which build toolchain the user has picked to build the source code. For the Qualcomm LLVM toolchain, the output have an unusual output as shown below: ``` clang version 8.0.12 Snapdragon LLVM ARM Compiler 8.0.12 (based on llvm.org 7.0+) Target: arm-unknown-linux-gnueabi Thread model: posix Repository: (ssh://git-hexagon-aus.qualcomm.com:...) InstalledDir: /pkg/qct/software/llvm/release/arm/8.0.12/bin ``` Another unusual pattern is the output of `path/to/ld.qcld --version`: ``` ARM Linker from Snapdragon LLVM ARM Compiler Version 8.0.12 ARM Linker based on LLVM version: 8.0 ``` The Meson logic is modified accordingly so that Meson can correctly determine toolchain as "LLVM aarch64 cross-compiler on GNU/Linux64 OS". This is the expected output of `meson --native-file native_file.ini --cross-file cross_file.ini build/aarch64-debug/`: ``` ... C++ compiler for the host machine: ... (clang 8.0.12 "clang version 8.0.12") C++ linker for the host machine: ... ld.lld 8.0.12 ... ```

2020-07-13Fix native builds on Windows ARM64 machinesNirbheek Chauhan1-13/+0
I made the mistake of always selecting the debug CRT for compiler checks on Windows 4 years ago: https://github.com/mesonbuild/meson/pull/543 https://github.com/mesonbuild/meson/pull/614 The idea was to always build the tests with debugging enabled so that the compiler doesn't optimize the tests away. But we stopped doing that a while ago, and also the debug CRT has no relation to that. We should select the CRT in the same way that we do for building targets: based on the options. On Windows ARM64, the debug CRT for ARM64 isn't always available, and the release CRT is available only after installing the runtime package. Without this, we will always try to pick the debug CRT even when --buildtype=debugoptimized or release.

2020-06-22compilers: Return CompilerArgs from compiler instanceDylan Baker1-0/+4
Since the CompileArgs class already needs to know about the compiler, and we really need at least per-lanaguage if not per-compiler CompilerArgs classes, let's get the CompilerArgs instance from the compiler using a method.
