We support this in a machine file:
```
[binaries]
pkgconfig = 'pkg-config'
pkg-config = 'pkg-config'
```
and you can use either one, because internally we look up both. If you
only set *one* of them, this plays awkwardly with setting $PKG_CONFIG,
since we don't know which one you set in the machine file and the
*other* one will be initialized from the environment instead.
In commit 22df45a319 we changed program
lookup of config-tool style dependencies to use the regular tool names
and only fall back on the strange internal names. This affected the
pkg-config class too.
The result is that instead of preferring `pkgconfig =` followed by
$PKG_CONFIG followed by `pkg-config =`, we inverted the lookup order.
This is a good idea anyway, because now it behaves consistently with
`find_program('pkg-config')`.
Unfortunately, we documented the wrong name in a bunch of places, and
also used the wrong name in various testsuite bits, which meant that if
you set $PKG_CONFIG and then ran the testsuite, it would fail.
Correct these references, because they are buggy.
One test case expected to find_program() a native copy for convenience
of testing against natively installed glib. Force it to resolve a native
copy.
wine64 used to be the way to run a 64-bit wineserver. It was removed due
to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1029536 despite
that bug report being about a bug in an unrelated symlink -- apparently
there's no recommended solution to starting a specific bitness of wine
on demand. The automagic `wine` I believe creates a wineprefix with
both, which is... probably not exactly efficient here? But whatever, not
worth fighting it. Just get this more or less working again.
Partial revert of commit cf23e34187. This
mostly moved existing arguments to the "right" location, but also
introduced new arguments that didn't previously exist -- which was
wrong.
... also, these cross files are used by CI (if they have a corresponding
.json file) and this change broke the CI. Because --target isn't a valid
gcc option, although clang/rustc do accept it. For GCC, the argument
parser decides you wanted --target-help, which prints documentation text
and then quits.
c_args are meant to be overridden by the user if needed (even via the
environment CFLAGS variables + -Doptimization=plain, for example),
so they should not contain any option that affect the multilib search
path. For example, a hypothetical native file like this:
[binaries]
c = gcc
[built-in options]
c_args = ['-m32']
would *not* build 32-bit binaries if -Dc_args is passed to meson.
Such options, instead should be in the [binaries] section. Adjust
the sample cross files included with meson.

This enables the fortran tests for Azure.
We only test on x64, because:
- ifort isn't arm64 compatible
- x86 may in theory exist, but Meson reports it cannot compile
executables
* 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.

fix ccomp meson configuration

add CompCert to meson (does not fully work, yet)
* remove unused import and s/cls/self/
fixes the two obvious LGTM warnings
* CompCert: Do not ignore unsupported GCC flags
Some are safe to ignore, however, as per
https://github.com/mesonbuild/meson/pull/7674, they should not be
ignored by meson itself. Instead the meson.build should take care to
select only those which are actually supported by the compiler.
* remove unused variable
* Only add arguments once.
* Apply suggestions from code review
Co-authored-by: Dylan Baker <dylan@pnwbakers.com>
* Remove erroneous ' ' from '-o {}'.format()
As noticed by @dcbaker
* added release note snippet for compcert
* properly split parameters
As suggested by @dcbaker, these parameters should be properly split into multiple strings.
Co-authored-by: Dylan Baker <dylan@pnwbakers.com>
* Update add_compcert_compiler.md
Added a sentence about the state of the implementation (experimental); use proper markdown
* properly separate arguments

Add a cross-file for MSVC UWP ARM64.
Bump cidata tag to get an updated install.ps1 script (run by run.ps1)
which sets the vcvars environment correctly when cross-compiling.
Since arranging the correct environment for simultaneous cross and
native 'cl' use is hard, this is test run uses '--cross-only' so we
don't require a native compiler.
Extend '--cross-only' so it also explicitly uses a machine file which
makes all build machine compilers unusable.
- Exceptions raised during subproject setup were ignored.
- Allow c_stdlib in native file, was already half supported.
- Eliminate usage of subproject variable name by overriding
'<lang>_stdlib' dependency name.
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
* environment: Fix passing always args to a number of less common linkers
These are mostly (oops xilink) proprietary linkers I can't use for
various reasons.
Fixes: #6332
* Add intelfix from scivision.
* Ifort fix from scivision.
* PGI fix from scivision.
* Cuda fix from scivision.
* Fix linker passing for armclang.
