As far as I can Tell, rust just handles this for us (it's always worked
with no special arguments from us). However, since we're going to add
support for base options for rust, we need to add the method.
When TemporaryDirectory() cleans up on __exit__ it sometimes throws
OSError noting that the dir isn't empty. This happens after the
first yield in this generator and leads to the exception being handled
which leads to a second yield.
contextlib.contextmanager() fails then since the function it wraps is only
allowed to yield once.
Fix this by not yielding again in the error case.
Fixes#7947
Using the std option, so now `rust_std=..` will work. I've chosen to use
"std" even though rust calls these "editions", as meson refers to
language versions as "standards", which makes meson feel more uniform,
and be less surprising.
Fixes: #5100
It is much easier to not try to parse options into complicated
structures until we actually collected all options: machine files,
command line, project()'s default_options, environment.
The implementation of the link variant was what should have been the
compiler variant, and there was no valid compiler variant, which meant
it was getting C code.
This abstraction is really useful, and most compilers could use it
(including D). It also will allow the Gnu mixins to work properly
without the CLikeCompiler in their mro.
So that every subclass doesn't have to reimplement it. Especially since
the Gnu implementation moved out of the CCompiler and into the
GnuLikeCompiler mixin
- Fixed using debug and optimization built-in options in MSVC.
- Fixed that VS backend does not create pdb files in release mode.
VS implicitly adds the debug fields if left out.
- Fix that it is possible to add debug info with ninja backend with
optimizations.
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.
Every class needs to set this, so it should be part of the base. For
classes that require is_cross, the positional argument remains in their
signature. For those that don't, they just allow the base class to set
their value to it's default of False.
