Even ones inside inline functions. This was a backwards compatibility
hack for Kotlin 1.4, where the inliner would crash if it attempted to
regenerate an anonymous object with no SMAP; that has been fixed in 1.5,
and ever since then trivial SMAPs could be inferred from line number
markers in methods.
There are three kinds of changes to tests in this commit:
* Some SMAPs are gone entirely - self-explanatory.
* Some SMAPs have narrower line ranges - that's because the old SMAP
had the range for the entire file, while the new one only maps up to
the last line number used in the class. There should be no
difference in behavior.
* Some "source file name" markers are removed in continuation objects
- continuations don't have any line numbers, so there's no debugging
information anyway. The actual source information is in the
containing class.
We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
A follow-up for KT-35006:
fun f() = foo {
bar()
}
inline fun foo(crossinline x: () -> Unit) = { x() }()
inline fun bar() = TODO()
does not provide the option to navigate to bar's call site at all.
* a writing source mapper has `mapLineNumber(line, file, class)` that
inserts a new SMAP entry and returns a fake line number from it;
* a copying source mapper has `mapLineNumber(line)` that uses an
existing SMAP to resolve the line number and call the former method
on a different source mapper;
* those two types are disjoint.
Specifically, this commit improves the stepping behavior of the IR
backend around functions with defaults.
- Improved line numbers in the default handler itself for better
stepping when inlined.
- Improved source information on default arguments
- Improved test coverage of stepping behavior in old and IR backends.
Improves the stepping behaviour around inline methods with default
arguments. In particular, we now accurately step through the
evaluation of default arguments, but do _not_ spuriously show the exit
from the $default handler.
If `mapLineNumber` was called in non-monotonic order, e.g. N then N+2
then N+1, the first two calls created a range that spans [N; N+2] but
the third call did not reuse it.
We should only insert a return statement at the end of a lambda or
function if the final statement is used as an expression (slice
USED_AS_RESULT_OF_LAMBDA and USED_AS_EXPRESSION).
