[Interpreter] Refactor bytecode generator test suite. Bytecode expectations have been moved to external (.golden) files, one per test. Each test in the suite builds a representation of the the compiled bytecode using BytecodeExpectationsPrinter. The output is then compared to the golden file. If the comparision fails, a textual diff can be used to identify the discrepancies. Only the test snippets are left in the cc file, which also allows to make it more compact and meaningful. Leaving the snippets in the cc file was a deliberate choice to allow keeping the "truth" about the tests in the cc file, which will rarely change, as opposed to golden files. Golden files can be generated and kept up to date using generate-bytecode-expectations, which also means that the test suite can be batch updated whenever the bytecode or golden format changes. The golden format has been slightly amended (no more comments about `void*`, add size of the bytecode array) following the consideration made while converting the tests. There is also a fix: BytecodeExpectationsPrinter::top_level_ was left uninitialized, leading to undefined behaviour.

[ignition] removed nop bytecode Nop bytecodes are required only for break locations in debugger. Since nop bytecode doesn't change program state we can remove all of them. There are at least two changes which this CL produce: - we don't provide break position when we load local variable (still provide when load variable from global), - we don't provide break position for statements without actual break positions (e.g. "a;") - these expressions should be super rare and user always can set breakpoint before or after this statement.

[inspector] improve return position of explicit return in non-async function Goal of this CL: explicit return from non-async function has position after return expression as return position (will unblock [1]). BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods. If one of these methods is called then next generated bytecode will get passed position. It's general treatment for most cases. Unfortunately it doesn't work for Returns: - debugger requires source positions exactly on kReturn bytecode in stepping implementation, - BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn generates more then one bytecode and general solution will put return position on first generated bytecode, - it's not easy to split BuildReturn function into two parts to allow something like following in BytecodeGenerator::VisitReturnStatement since generated bytecodes are actually controlled by execution_control(). ..->BuildReturnPrologue(); ..->SetReturnPosition(stmt); ..->Return(); In this CL we pass ReturnStatement through ExecutionControl and use it for position when we emit return bytecode right here. So this CL only will improve return position for returns inside of non-async functions, I'll address async functions later.

[inspector] improve return position of explicit return in non-async function Goal of this CL: explicit return from non-async function has position after return expression as return position (will unblock [1]). BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods. If one of these methods is called then next generated bytecode will get passed position. It's general treatment for most cases. Unfortunately it doesn't work for Returns: - debugger requires source positions exactly on kReturn bytecode in stepping implementation, - BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn generates more then one bytecode and general solution will put return position on first generated bytecode, - it's not easy to split BuildReturn function into two parts to allow something like following in BytecodeGenerator::VisitReturnStatement since generated bytecodes are actually controlled by execution_control(). ..->BuildReturnPrologue(); ..->SetReturnPosition(stmt); ..->Return(); In this CL we pass ReturnStatement through ExecutionControl and use it for position when we emit return bytecode right here. So this CL only will improve return position for returns inside of non-async functions, I'll address async functions later.

[Interpreter] Refactor bytecode generator test suite. Bytecode expectations have been moved to external (.golden) files, one per test. Each test in the suite builds a representation of the the compiled bytecode using BytecodeExpectationsPrinter. The output is then compared to the golden file. If the comparision fails, a textual diff can be used to identify the discrepancies. Only the test snippets are left in the cc file, which also allows to make it more compact and meaningful. Leaving the snippets in the cc file was a deliberate choice to allow keeping the "truth" about the tests in the cc file, which will rarely change, as opposed to golden files. Golden files can be generated and kept up to date using generate-bytecode-expectations, which also means that the test suite can be batch updated whenever the bytecode or golden format changes. The golden format has been slightly amended (no more comments about `void*`, add size of the bytecode array) following the consideration made while converting the tests. There is also a fix: BytecodeExpectationsPrinter::top_level_ was left uninitialized, leading to undefined behaviour.

[inspector] improve return position of explicit return in non-async function Goal of this CL: explicit return from non-async function has position after return expression as return position (will unblock [1]). BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods. If one of these methods is called then next generated bytecode will get passed position. It's general treatment for most cases. Unfortunately it doesn't work for Returns: - debugger requires source positions exactly on kReturn bytecode in stepping implementation, - BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn generates more then one bytecode and general solution will put return position on first generated bytecode, - it's not easy to split BuildReturn function into two parts to allow something like following in BytecodeGenerator::VisitReturnStatement since generated bytecodes are actually controlled by execution_control(). ..->BuildReturnPrologue(); ..->SetReturnPosition(stmt); ..->Return(); In this CL we pass ReturnStatement through ExecutionControl and use it for position when we emit return bytecode right here. So this CL only will improve return position for returns inside of non-async functions, I'll address async functions later.

[Interpreter] Refactor bytecode generator test suite. Bytecode expectations have been moved to external (.golden) files, one per test. Each test in the suite builds a representation of the the compiled bytecode using BytecodeExpectationsPrinter. The output is then compared to the golden file. If the comparision fails, a textual diff can be used to identify the discrepancies. Only the test snippets are left in the cc file, which also allows to make it more compact and meaningful. Leaving the snippets in the cc file was a deliberate choice to allow keeping the "truth" about the tests in the cc file, which will rarely change, as opposed to golden files. Golden files can be generated and kept up to date using generate-bytecode-expectations, which also means that the test suite can be batch updated whenever the bytecode or golden format changes. The golden format has been slightly amended (no more comments about `void*`, add size of the bytecode array) following the consideration made while converting the tests. There is also a fix: BytecodeExpectationsPrinter::top_level_ was left uninitialized, leading to undefined behaviour.

Replace Context::closure with Context::scope_info, allowing closure to die. There are likely cleanups that can be done after this CL: - context-related functions in the interpreter and compiler take ScopeInfo as well as ScopeType and slot-count as input. The latter 2 should be directly derived from the former. We should be able to drop FunctionContextParameters. - ContextExtension is probably not needed anymore, since we now always have the correct scope_info directly in the SCOPE_INFO_INDEX slot.

[ignition] removed nop bytecode Nop bytecodes are required only for break locations in debugger. Since nop bytecode doesn't change program state we can remove all of them. There are at least two changes which this CL produce: - we don't provide break position when we load local variable (still provide when load variable from global), - we don't provide break position for statements without actual break positions (e.g. "a;") - these expressions should be super rare and user always can set breakpoint before or after this statement.
