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 ;-)
It was done to include them in `meson subprojects foreach` without
--types argument, but it's better to special case missing --types and
include wraps that have type=None too. It was a bad idea because that
was messing them in `meson subprojects update`, now they are ignored by
that command.
If revision is a tag that does not exist locally, `git fetch origin
<revision>` won't create it and checkout will fail. Using --refmap
ensures that references exists locally.
This is a test for https://github.com/mesonbuild/meson/pull/7021, to
verify that `link.exe` uses the correct architecture when targeting
ARM64. Can be extended to other cross targets later.
There are two problems here. The first is that we're doing manual monkey
patching which is fragile and verbose, when unittest.mock is designed
specifically to solve this exact problem. The second is that we're
monkey patching os.environ at two different levels with the same
information. So let's only do it once.
When building with vs2019 (not ninja), a path length error will be thrown
if the path to a resource file is even remotely deep within the tree.
This is largely because the target name includes the string "Windows
resource for file 'full path'", which is then expanded twice (once for
the .vcxproj itself, and once for IntDir) and added to the full path.
When combined with the tiny path limits on Windows, it is easy to exceed
path limits.
This error is largely avoided by the ninja back-end. Unlike the
vs back-end, the ninja back-end does not use target.get_id() as part of
the project file path, nor does it use target.get_id() as part of
get_target_private_dir().
Example error:

The fully qualified file name must be less than 260 characters.
If the architectures are taken from the output of "clang-cl --version",
we need to convert these names into names that the MSVC tools accept
as the -machine: parameter.
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.
* 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

I wrote this to convert run_tests.get_backend_commands() over to the
new meson wrappers, but that turned out to be harder than I expected,
so just splitting this out for now.
- "Go To Document" action previously only worked
on c/cpp files which had the include directories
set but it was not possible to move from header to another header.
On my machine this spawns 24 processes and then runs like the single
test I asked it to run. With this change, running a single test goes
from 7 seconds to less than a second.
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.
This reverts commit 8ee1c9a07a.
No rationale was given for this change prior to merging. After the fact
it was described as desired by distro packagers, however as a distro
packager I believe this commit hurts me.
From a distro packaging perspective, we primarily care about one thing:
previously building code should still build. Hence, -Werror is bad for
our use case. meson handles this via -D werror which is different from
-D warning_level and as long as the former is disabled, warnings in the
build do not cause harm (but may attract review attention for upstream
to fix).
buildtype is a completely unrelated concern, and the intention for
=plain is to disable debug or optimization settings that result in
codegen differences and thus different built artifacts. This must not
happen in distro builds because the *distributed programs* should
conform to policy settings.
Unfortunately, completely disabling warnings happens silently, and
cannot be overridden even if you really, really believe you know what
you're doing. It is thematically broken, since use of
add_project_arguments() to add more -W flags is not likewise ignored.
But if you try to add -Wall in that manner, meson will lecture you to
use warning_level which you cannot do. And if you have custom warning
flags which depend on options enabled by judicious use of -Wall via
default_options: 'warning_level=1', then you end up with generated
warnings complaining about your command line rather than your code, such
as:
cc1: warning: ‘-Wformat-y2k’ ignored without ‘-Wformat’ [-Wformat-y2k]
cc1: warning: ‘-Wformat-extra-args’ ignored without ‘-Wformat’ [-Wformat-extra-args]
cc1: warning: ‘-Wformat-zero-length’ ignored without ‘-Wformat’ [-Wformat-zero-length]
cc1: warning: ‘-Wformat-contains-nul’ ignored without ‘-Wformat’ [-Wformat-contains-nul]
cc1: warning: ‘-Wformat-security’ ignored without ‘-Wformat’ [-Wformat-security]
which then break the build with -Werror.
Throughout all this, a buildtype of "plain" does *not* disable -D
werror=true, which is the part where distro builds actually break down!
Users who both wish to disable debug/optimization codegen, *and* disable
warning commentary, are encouraged to do so by doing both, not by doing
one and having the other be assumed.
