* 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.

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

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
Emscripten does have a stand alone linker, wasm-ld. This patch adds the
linker, adds detection for the linker, and removes the IsLinkerMixin for
emscripten. This is a little more correct, and makes the code a lot
cleaner and more robust.
This makes two basic changes, 1 it moves the name of the linker into the
linker class, this should reduce the number of errors and typos, and
ensure that a linker always has one name. This then renames the linkers
to have more consistent names.
Posix/gnu linkers are called ld.<name>: ld.gold, ld.lld, ld.solaris.
Apple linkers are renamed ld64.
These are pretty much all over the place because I never intended them
to be exposed to the meson source language, they were meant just for
documentation.
this can be useful for if/elif where linker behaviors must be
considered.
For example, clang with "link" vs gcc with "ld.bfd" etc.

I originally liked "solaris", but I've changed my mind. Both illumos
(the open-source fork of OpenSolaris) and Oracle's closed-source
Solaris are identified by the same token, and there are differences
between them; so using "sunos" as a sort "supertype" for both makes
sense to me.
* c_function_attributes: remove 'protected' from 'visibility'
This doesn't exist on macos with the apple compiler, which always causes
failures.
Fixes#5530
* compilers: Add split visibility checks to has_function_attribute
These check for a single visibility at a time, rather than all four at
once. This allows for finer grained searches, and should make using
these checks safer across operating systems.
Because the Intel compiler behaves significantly differently on windows
than it does on Linux and MacOS I've decided it would be better to
follow the clang/clang-cl split and make id "intel-cl" on windows
(leaving "intel" alone on Linux and Mac). Since we've never supported
ICL and it hasn't worked in the past I think this is an okay change to
make.
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).
Autotools will add endianess to the name of the architecture in some
cases (such as ppc64le vs ppc64) meson doesn't do this. It's worth
noting this in the documentation.
