K2MetadataCompiler is a compiler facade similar to K2JVMCompiler and
K2JSCompiler and it produces .kotlin_metadata files. Each .kotlin_metadata file
contains the binary data which is a serialized BuiltIns protobuf message.
There's no 'kotlinc-***' script yet though, so to run this compiler currently
invoke this:
KOTLIN_COMPILER=org.jetbrains.kotlin.cli.metadata.K2MetadataCompiler kotlinc
- drop 'kotlin-runtime' and other dependencies which are exported by
other modules ('util' and 'util.runtime' in case of 'kotlin-runtime')
- make all Kotlin modules from the compiler depend on 'util' for clarity
- put 'util' and 'util.runtime' to the bottom of the list everywhere: when
kotlin-runtime gets reflection, classes from core/ should have higher
priority than their previous versions from kotlin-runtime.jar
Cleanup module dependencies: a lot of modules depended on 'frontend.java' just
to use something from 'util' module, exported by 'frontend.java', whereas they
really need nothing from 'frontend.java'. Also 'frontend.java' just exported
'util', not using anything from it.
Create a new 'util.runtime' module, which will be available at runtime. Make
'util' export 'util.runtime' and make all modules who needed these utils depend
on 'util' directly instead of 'frontend.java'
Major changes: ASM is switched from vanilla 3.3 to a 4.0 with renamed packages,
because this is done inside IDEA and we depend on that transitively.
Thus the jarjar renaming in build.xml, old library binaries deleted.
Also we now depend on exact IDEA build (EAP), not "last successful".
