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.

// Please, when your changes cause failures in bytecodeText tests for 'for' loops,
|
|
// examine the resulting bytecode shape carefully.
|
|
// Range and progression-based loops generated with Kotlin compiler should be
|
|
// as close as possible to Java counter loops ('for (int i = a; i < b; ++i) { ... }').
|
|
// Otherwise it may result in performance regression due to missing HotSpot optimizations.
|
|
// Run Kotlin compiler benchmarks (https://github.com/Kotlin/kotlin-benchmarks)
|
|
// with compiler built from your changes if you are not sure.
