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.
Currently we do some crazy hackery where we add extra properties to a
Popen object and return that. That's crazy. Especially since some of our
hackery is to delete attributes off of the Popen we don't want. Instead,
let's just have a discrete type that has exactly the properties we want.
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 ;-)
