This commit introduces a new entrypoint for the IR backend, and starts
the work of accomodating the evaluator in psi2ir.
The evaluator expects a certain class and method structure of the
compiled fragment, but PSI is only supplied for the actual fragment.
So, to that end, this commit introduces a new "front end" of psi2ir
that "synthesizes" the module, class and method structure around the
fragment before calling into the existing psi2ir pipeline to obtain
the IR for the fragment.
The primary complication so far is handling the captured variables of
the fragment: they are mapped to parameters of the method surrounding
the fragment, and passed as arguments on evaluation. Hence, the IR
translation of the fragment needs to remap captured variables to the
appropriate parameter, in essentially all places they can be referred
to in the fragment (and hence in psi2ir). This commit introduces a
decorated symbol table that intercepts symbol look-ups and remaps as
appropriate.
Other cases that dispatches based on descriptor (see
`CallGenerator.kt`) needs other metadata to generate correct code.
It also introduces a shim in DeserializedContainerSource in the psi2ir
pipeline to facilitate facade class generation for the code that is
being debugged (which are generated as "external ir declarations").
Finally, in passing we resolve a small leftover from previous
refactoring that left an asssertion re. allowing IR to _assign_ to
parameters of methods.
There seems to be no point in configuring the compiler argument per
project. This argument will be deleted soon anyway, when we remove
support for JDK 1.6 & 1.7.
Also remove `disableDeprecatedJvmTargetWarning`. It didn't have any
effect in all modules where it was applied because these modules
reassign `freeCompilerArgs` anyway, with
`-Xsuppress-deprecated-jvm-target-warning` in it.
KotlinJvmBinaryClass.AnnotationArrayArgumentVisitor didn't cover the
case when the element type is an Annotation. Therefore, when the
compiler read an array of annotations from JVM binary classes built from
Kotlin sources, it got an empty array regardless of what was written in
the bytecode.
For example, Foo.value below is read as an empty array when SomeClass
resides in another Kotlin module.
@Foo(
value = [Bar(1), Bar(2)]
)
class SomeClass
Move it to build-common where it's still used in incremental compilation
caches, and simplify a bit. In the future, it'll make sense to remove it
completely and to avoid writing it to caches. In this commit, I don't do
that to prevent the IC cache version to be updated, causing rebuilds for
all JPS projects.
#KT-41758
Report a separate error when class files compiled with FIR are in
dependencies, in addition to the one for class files compiled with FE
1.0 + JVM IR.
#KT-43592
Introduce an enum DeserializedContainerAbiStability with two values.
This is needed in order to support another reason for ABI instability in
a subsequent commit, namely "unstable because compiled by FIR".
