// IMPORTANT! // 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. fun consume(i: Int) {} fun f(r: IntRange) { for (i in r) { consume(i) } } // 0 iterator // 0 getStart // 0 getEnd // 1 getFirst // 1 getLast // 0 getStep // 2 ISTORE // 5 ILOAD // 1 IINC // 1 IF_ICMPGT // 1 IF_ICMPEQ // 2 IF
