* Fix and test for assert/crash in v8 inlining of local functions in qml modev5.1.0-rc1David McFarland2013-05-314-0/+42
| | | | | | | | | | | | | | | When v8 tries to inline a local function which has been flagged is_qml_global, the assert "CHECK(location_ != __null)" fails. This happens because of the early out in RecordTypeFeedback for is_qml_global. I've limited the early out to UNALLOCATED variables with is_qml_global. bug: https://bugreports.qt-project.org/browse/QTBUG-31366 Change-Id: I360ef1a05a970589159686cf3100cb70de9ae29d Reviewed-by: Alan Alpert <aalpert@blackberry.com> Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Always initialise symbol_id for ASCII symbolsPhilip Lorenz2012-09-243-0/+55
| | | | | | | | | | | | | Commit 30662b5d64ff633f57d89290da2a85507d561187 dropped the default initialisation of the symbol_id for ASCII characters. This leads to problems when trying to access the symbol_id when the symbol was not instantiated via AsciiSymbolKey (e.g. via SubStringAsciiSymbolKey). Additionally, AsciiSymbolKey does not guarantee the presence of a symbol_id in case the SMI value space has been exhausted.

* Fix assert in stub-cache.cc when loading qml-mode functionsKent Hansen2012-03-203-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c511fa8a6a631e45ee4075453bcb2eeb7f01ba63 introduced a regression that could cause an assert in V8 to be triggered: Fatal error in ../3rdparty/v8/src/stub-cache.cc, line 1171 CHECK(!CallIC::Contextual::decode( Code::ExtractExtraICStateFromFlags(flags))) failed The assert would be triggered when 1) the "QML global object" (implicit receiver in qml-mode evaluation) defined more than 12 properties, and 2) a function property of the QML global object was looked up at least twice from JavaScript. In particular, the V8 IC would assert that there should be an explicit receiver when advancing the function lookup from pre-monomorphic state to monomorphic state. (The magic number 12 (number of properties needed to trigger the bug) is the kMaxFastProperties constant. This is the threshold where V8 switches to using a dictionary for the object storage, instead of using "fast properties" (array).) The IC correctly determines that the property holder object (the QML global object) is not the JS Global Object, and hence compiles it as a "normal" call, in which it asserts that "there must be an explicit receiver here". But in QML mode, the receiver can be implicit when the holder is the QML global object. Propagate this information to the stub cache to avoid the assert triggering. The generated JIT code still works as expected when the receiver is implicit (i.e., the receiver is always loaded). None of the other property/function-load IC handlers have a similar assert. It might be worth investigating whether "QML global object" property loading should have dedicated cache stubs; e.g. a ComputeCallQmlGlobal() akin to ComputeCallGlobal(). This could potentially simplify/speed up the generated code, since we can take advantage of the read-only nature of the QML global object type right off the bat. But that's a bigger change that would require all the JIT compilers and the GC to be adapted.

* Let V8 throw the exception when QML property lookup failsKent Hansen2012-03-144-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should be squashed into the "Introduce a QML compilation mode" commit (8a4d849a0152c76bd9107a1b38a641cf8c0ff226) the next time V8 is rebased. In normal (non-QML) mode, when a global property lookup fails (implicit receiver ("this") object), V8 decides to throw an exception iff the expression evaluation is not part of a "typeof" evaluation. If it is evaluated as part of "typeof", the result silently becomes "undefined". This is the expected behavior as per the ECMA-262 standard; "typeof" shouldn't throw a ReferenceError even if the expression involves a global variable that doesn't exist. This commit brings the QML mode behavior in line with normal mode. When the receiver object is a QML global object, V8 up until now hasn't detected whether it should throw an error in that case. The QML implementation has been working around that by explicitly throwing the ReferenceError in the QML context wrapper, but that breaks the "typeof" operator in QML mode. The QML context wrapper should rather return an empty handle, and leave it up to V8 to throw the exception as appropriate. This also reverts the parts of the original QML mode patch that changed the RelocInfo mode for QML variables, since V8 relies precisely on this mode to know whether it's evaluating a "typeof". (It's no longer clear why the RelocInfo mode was modified in the first place.)
