The flag --trace-ignition-dispatches has been broken for a long time, since it was not designed to work with bytecode handlers that are generated ahead of time by mksnapshot. This splits the existing --trace-ignition-dispatches logic into two separate parts: 1. A gn argument which instructs mksnapshot to include dispatch counting in the bytecode handlers, and ensures that the Interpreter allocates the array of counters, and 2. A runtime flag which enables the ignition-statistics extension which implements the JS-accessible function getIgnitionDispatchCounters().

The typical use of assertThrowsEquals is to check that a specific object is thrown. However, assertEquals only does a proper equality check for primitive types, not for complex types. Using assertSame does a reference equality check on objects, which is more what you would expect from assertThrowsEquals. For exception kind testing, assertThrowsEquals actually did not work correctly, assertThrows is better for that case.

This fixes String::MakeExternal() to bail out if the subject string doesn't fit a regular ExternalString, instead of creating a short external string. The observation here is that for short external strings the overhead of having to have the StringResource plus going to the runtime/C++ for each and every character access from JavaScript land is probably bigger than the anticipated benefits. If this turns out to be wrong and there's a real benefit, we should make use of ThinStrings instead of having a separate way to represent external strings.

The `FAST_` prefix doesn’t make much sense — they’re all just different cases with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS` vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either. This patch renames the FAST elements kinds as follows: - e.g. FAST_ELEMENTS => PACKED_ELEMENTS - e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS The following exceptions are left intact, for lack of a better name: - FAST_SLOPPY_ARGUMENTS_ELEMENTS - SLOW_SLOPPY_ARGUMENTS_ELEMENTS - FAST_STRING_WRAPPER_ELEMENTS - SLOW_STRING_WRAPPER_ELEMENTS This makes it easier to reason about elements kinds, and less confusing to explain how they’re used.

Similar to JSCall, we can also replace uninitialized JSConstruct nodes with SOFT deopts to ensure that we don't generate unnecessary dead code. This for example shows up in the hot parts of the Node event emitter currently where the generic code for handling events with 4 or more parameters might not have been run, but we still generate most of the code because the new Array call in the beginning is not turned into a SOFT deopt immediately. Drive-by-fix: Also refactor the BytecodeGraphBuilder's handling of Construct bytecodes a bit to reduce the amount of code duplication.

This removes the --turbo flag and solely relies on the filter pattern provided via --turbo-filter when deciding whether to use TurboFan. Note that disabling optimization wholesale can still be done with --no-opt, which should be used in favor of --no-turbo everywhere. Also note that this contains semantic changes to the TurboFan activation criteria. We respect the filter pattern more stringently and no longer activate TurboFan just because the source contains patterns forcing use of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

ThrowIfHole bytecodes were handled by introducing deopt points to check for a hole. To avoid deopt loops a hole check protector was used to generate control flow if there was a deopt due to a hole. However, the normal control flow version should be as fast as the deopt version in general. The deopt version could potentially consume less compile time but it may not be worth the complexity added. Hence simplifying it to only construct the control flow.

Once we enabled --turbo by default we need to turn all the implications off with --no-turbo as well. Chrome sets flags in V8 using SetFlagFromString, which enforces the implications each time it is called. Therefore, if --turbo is enabled by default, and an unrelated flag is set, the turbo implications are enabled but not later disabled if we set --no-turbo. To fix this, add negative implications as well.

Allocate the registers used as arguments to a call on-demand after visiting the argument (or reciever). This means that the visited expression can use registers that would otherwise have been allocated for arguments which haven't been visited yet. The reason for doing this is to avoid keeping things live in registers unecessarily for chained function calls, which avoids a memory leak for functions which chain a large number of calls with large temporary arguments / recievers.

This CL further extends the debug wrapper, migrates around 60 tests, and removes a few tests that use functionality we will not support anymore. In more detail: * Removed tests that use: * enable/disable individual breakpoints * invocationText() * the ScriptCollected event * showBreakPoints * evalFromScript (and similar) * mirror.constructedBy and mirror.referencedBy * event_data.promise() * Some frame.evaluate uses were adapted since due to differences between remote objects (inspector) and mirrors. For instance, exceptions are currently not recreated exactly, since the inspector protocol does not give us the stack and message separately. Other objects (such as 'this' in debug-evaluate-receiver-before-super) need to be explicitly converted to a string before the test works correctly. * Ensure that inspector stores the script before sending ScriptParsed and ScriptFailedToParse events in order to be able to use the script from within those events. * Better remote object reconstruction (e.g. for undefined and arrays). * New functionality in wrapper: * debuggerFlags().breakPointsActive.setValue() * scripts() * execState.setVariableValue() * execState.scopeObject().value() * execState.scopeObject().property() * execState.frame().allScopes() * eventData.exception() * eventData.script() * setBreakPointsActive() BUG=v8:5530 Review-Url: https://codereview.chromium.org/2497973002 Cr-Commit-Position: refs/heads/master@{#41019}

This CL adds support for: * conditional breaks in setBreakpoint, * locals in frame.local{Count,Name,Value}, * evaluation on a frame in frame.evaluate, * and more detailed scope information in scopeObject. Uses of several functions that are not covered by the inspector protocol and are only used in tests have been removed. Local handling has been modified to also include arguments as locals. Inspector differs in this regard from our FrameDetails in that arguments are always shown as locals. Argument-related functions were removed.

This flag is on by default for now. Whenever heuristics in the compiler pipeline decide to use Ignition+TurboFan, then {BytecodeGraphBuilder} is active. Removing the flag reduces maintenance overhead. R=mvstanton@chromium.org Review-Url: https://codereview.chromium.org/2437103002 Cr-Commit-Position: refs/heads/master@{#40639}
