`{}` for decls
`{p}` for enum fields
`{p_}` for struct fields and in contexts following a `.`
Elsewhere, `{p}` was used since it's equivalent to the old behavior.
Now that `-femit-docs` includes all modules, including the builtin
module, in the generated source tarball, it makes sense to apply the
same logic to the std-docs server. std-docs constructs its own tarball,
so a different approach is needed to achieve the same end result.
This takes the code that was previously in src/Compilation.zig to turn resinator diagnostics into Zig error bundles and puts it in resinator/main.zig, and then makes resinator emit the resulting error bundles via std.zig.Server (which is used by the build runner, etc). Also adds support for turning Aro diagnostics into ErrorBundles.
This moves .rc/.manifest compilation out of the main Zig binary, contributing towards #19063
Also:
- Make resinator use Aro as its preprocessor instead of clang
- Sync resinator with upstream
Part of #19063.
Primarily, this moves Aro from deps/ to lib/compiler/ so that it can be
lazily compiled from source. src/aro_translate_c.zig is moved to
lib/compiler/aro_translate_c.zig and some of Zig CLI logic moved to a
main() function there.
aro_translate_c.zig becomes the "common" import for clang-based
translate-c.
Not all of the compiler was able to be detangled from Aro, however, so
it still, for now, remains being compiled with the main compiler
sources due to the clang-based translate-c depending on it. Once
aro-based translate-c achieves feature parity with the clang-based
translate-c implementation, the clang-based one can be removed from Zig.
Aro made it unnecessarily difficult to depend on with these .def files
and all these Zig module requirements. I looked at the .def files and
made these observations:
- The canonical source is llvm .def files.
- Therefore there is an update process to sync with llvm that involves
regenerating the .def files in Aro.
- Therefore you might as well just regenerate the .zig files directly
and check those into Aro.
- Also with a small amount of tinkering, the file size on disk of these
generated .zig files can be made many times smaller, without
compromising type safety in the usage of the data.
This would make things much easier on Zig as downstream project,
particularly we could remove those pesky stubs when bootstrapping.
I have gone ahead with these changes since they unblock me and I will
have a chat with Vexu to see what he thinks.
