CoroutineTransformermethodVisitor attempts to extend the ranges
of local variables in various situations. Probably in an attempt
to give a better debugging experience. However, all of these
range extensions lead to invalid local variable tables where
something is in the local variable table where nothing is in the
corresponding slot.
The code that extends variables to the next suspension point
instead of ending them when they are no longer live has issues
with loops. When resuming and reentering the loop, the locals
table will mention a local that we did not spill and which
is therefore not restored when resuming.
The code that extends local variable table entries if there
are no suspension points between two entries doesn't work
for code such as:
```
var s: String
if (suspendHere() == "OK") {
s = "OK"
} else {
s = "FAIL"
}
```
If the local variable ranges are collapsed into one, one of
the branches will have the local defined in the local variable
table before the slot is initialized.
Gradle's detached configurations doesn't respect extends from relation
to other configurations due to gradle bug.
In fact extendsFrom isn't required for resolvableMetadataConfiguration
business logic. It is enough to include all originalDependencies to
freshly created detached configuration.
^KT-46417 Fixed
This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
... as that is not supported by the underlying mechanism.
Build service that holds info about the incremnetal compilation
may be instantiated only during execution, and multiple tasks may
try to do that. Because the container which holds info about all
build services is not thread-safe, this change adds synchronization.
Fixes #KT-46820
Before this commit, FIR mangler effectively dropped f/o parameter with
invisible type from this module. It could lead to signature clashes.
Now we insert classId in mangler string instead.
This fixes FIR bootstrap.
