Previously JS IR versions of stdlib and kotlin-test were build
by default using compiler previously built on a buildserver.
It had some issues:
- This required us to advance bootstrap every time we made any
incompatible IR changes. This happens often since IR ABI is
not quite stable yet.
- We never tested the exact combination of compiler and stdlib we publish
We tested:
- new compiler with new stdlib build by new compiler (in box tests)
- old compiler with new stdlib build by old compiler (in stdlib tests)
We published:
- new compiler with new stdlib build by old compiler
After this change JS IR compiler tests, builds and publishes
single configuration:
new compiler with new stdlib build by new compiler
JS IR stdlib and kotlin-test are now built using JavaExec of CLI instead
of Gradle plugin to avoid troubles of loading a freshly built plugin.
This also allows to have a granular dependencies: we don't rebuild klib
if we changed a lowering in a compiler backend, but we do rebuild it if
we changed IR serialization algorithm.
LazyIR was emitted because plugin was not able to declare symbols, only to reference them.
Moreover, declarations added by frontend plugin were also unbound symbols produced by psi2ir,
and declaration stub generator was stubbing them with LazyIR – therefore access to global symbol table is not enough for plugins. IrProvider won't help here, because some functions produced by plugin have circular dependencies.
By moving compiler plugins step between psi2ir and declaration stub generator, both problems are resolved
– unbound symbols produced by psi2ir and compiler plugins are declared where they would be declared if this was a user code,
and only unbound symbols left are external dependencies, which is a correct input for lazy ir.
- Use local uniqID local indexation file-local
- Rethink the way declaration is looked for
- Store in public file index only publicly accessible symbols
- refactor API
- code clean up
- remove IrModule header
- put IrDeclaration and its body into separate files
- use only one type of IrData index
- separate deserialization of declarations and its bodies
- introduce FqName message
Add directory libraries/stdlib/wasm as a placeholder for WASM runtime library
Copy built-ins from core/builtins
Add ExcludeFromCodegen annotation for internal needs
