// 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 f() { for (c in "123") { print(c) } } // Different locals slot numbers are used in JVM vs JVM IR for loop and induction variables. // JVM_TEMPLATES // 1 ISTORE 0\s+L3 // 1 ILOAD 0\s+INVOKEVIRTUAL java/io/PrintStream.print \(C\)V // 1 LOCALVARIABLE c C L3 L\d+ 0 // JVM_IR_TEMPLATES // 1 ISTORE 2\s+L3 // 1 ILOAD 2\s+INVOKEVIRTUAL java/io/PrintStream.print \(C\)V // 1 LOCALVARIABLE c C L3 L\d+ 2
