[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.

constant pool: [
[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).

[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).

[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.

[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).

[Interpreter] Replace BytecodeRegisterAllocator with a simple bump pointer. There are only a few occasions where we allocate a register in an outer expression allocation scope, which makes the costly free-list approach of the BytecodeRegisterAllocator unecessary. This CL replaces all occurrences with moves to the accumulator and stores to a register allocated in the correct scope. By doing this, we can simplify the BytecodeRegisterAllocator to be a simple bump-pointer allocator with registers released in the same order as allocated. The following changes are also made: - Make BytecodeRegisterOptimizer able to use registers which have been unallocated, but not yet reused - Remove RegisterExpressionResultScope and rename AccumulatorExpressionResultScope to ValueExpressionResultScope - Introduce RegisterList to represent consecutive register allocations, and use this for operands to call bytecodes. By avoiding the free-list handling, this gives another couple of percent on CodeLoad. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2369873002 Cr-Commit-Position: refs/heads/master@{#39905}

[Interpreter] Replace BytecodeRegisterAllocator with a simple bump pointer. There are only a few occasions where we allocate a register in an outer expression allocation scope, which makes the costly free-list approach of the BytecodeRegisterAllocator unecessary. This CL replaces all occurrences with moves to the accumulator and stores to a register allocated in the correct scope. By doing this, we can simplify the BytecodeRegisterAllocator to be a simple bump-pointer allocator with registers released in the same order as allocated. The following changes are also made: - Make BytecodeRegisterOptimizer able to use registers which have been unallocated, but not yet reused - Remove RegisterExpressionResultScope and rename AccumulatorExpressionResultScope to ValueExpressionResultScope - Introduce RegisterList to represent consecutive register allocations, and use this for operands to call bytecodes. By avoiding the free-list handling, this gives another couple of percent on CodeLoad. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2369873002 Cr-Commit-Position: refs/heads/master@{#39905}

[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.

[Interpreter] Replace BytecodeRegisterAllocator with a simple bump pointer. There are only a few occasions where we allocate a register in an outer expression allocation scope, which makes the costly free-list approach of the BytecodeRegisterAllocator unecessary. This CL replaces all occurrences with moves to the accumulator and stores to a register allocated in the correct scope. By doing this, we can simplify the BytecodeRegisterAllocator to be a simple bump-pointer allocator with registers released in the same order as allocated. The following changes are also made: - Make BytecodeRegisterOptimizer able to use registers which have been unallocated, but not yet reused - Remove RegisterExpressionResultScope and rename AccumulatorExpressionResultScope to ValueExpressionResultScope - Introduce RegisterList to represent consecutive register allocations, and use this for operands to call bytecodes. By avoiding the free-list handling, this gives another couple of percent on CodeLoad. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2369873002 Cr-Commit-Position: refs/heads/master@{#39905}

[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.

[Interpreter] Replace BytecodeRegisterAllocator with a simple bump pointer. There are only a few occasions where we allocate a register in an outer expression allocation scope, which makes the costly free-list approach of the BytecodeRegisterAllocator unecessary. This CL replaces all occurrences with moves to the accumulator and stores to a register allocated in the correct scope. By doing this, we can simplify the BytecodeRegisterAllocator to be a simple bump-pointer allocator with registers released in the same order as allocated. The following changes are also made: - Make BytecodeRegisterOptimizer able to use registers which have been unallocated, but not yet reused - Remove RegisterExpressionResultScope and rename AccumulatorExpressionResultScope to ValueExpressionResultScope - Introduce RegisterList to represent consecutive register allocations, and use this for operands to call bytecodes. By avoiding the free-list handling, this gives another couple of percent on CodeLoad. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2369873002 Cr-Commit-Position: refs/heads/master@{#39905}

[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.

constant pool: [
[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).

[Interpreter] Replace BytecodeRegisterAllocator with a simple bump pointer. There are only a few occasions where we allocate a register in an outer expression allocation scope, which makes the costly free-list approach of the BytecodeRegisterAllocator unecessary. This CL replaces all occurrences with moves to the accumulator and stores to a register allocated in the correct scope. By doing this, we can simplify the BytecodeRegisterAllocator to be a simple bump-pointer allocator with registers released in the same order as allocated. The following changes are also made: - Make BytecodeRegisterOptimizer able to use registers which have been unallocated, but not yet reused - Remove RegisterExpressionResultScope and rename AccumulatorExpressionResultScope to ValueExpressionResultScope - Introduce RegisterList to represent consecutive register allocations, and use this for operands to call bytecodes. By avoiding the free-list handling, this gives another couple of percent on CodeLoad. BUG=v8:4280 Review-Url: https://codereview.chromium.org/2369873002 Cr-Commit-Position: refs/heads/master@{#39905}

[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.

constant pool: [
[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).
