* jsruntime: silence msvc warning 4201 (nameless struct/union)Tim Blechmann2024-02-061-0/+3
| | | | | | | | | qml's private headers are pulled into binaries when using the qml compiler. we should keep the warnings out of downstream code Pick-to: 6.5 6.6 6.7 Change-Id: I330b5f76d7846b5f2e5f2a4c1ece95b58c67a876 Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>

* QML: Implement QObjectMethod::virtualCallWithMetaTypesUlf Hermann2023-09-281-0/+3
| | | | | | | | | | | | We can use the same mechanism we have in place when calling typed JavaScript functions. The type coercion is generalized and moved to qv4jscall_p.h. We also use the correct JavaScript coercion in the rare fallback case where the types are actually different.

| | | | | | | | | | | This is where it belongs. We need to apply some tricks to avoid cyclic includes, but that's better than what we have so far. Also, sort and clean up the includes in the affected files.

* QML: Encode "missing" line number as negated address of stack frameUlf Hermann2023-05-091-0/+2
| | | | | | | | | | | | | | | This way we can identify which entry in a stack frame to amend when processing an exception in generated code. However, negative line numbers are also used to signal the position of "Ret" instructions. Since you cannot throw an exception from a "Ret" instruction, those cannot collide, but we cannot qAbs() the line number anymore when saving it in the stack trace. We have to qAbs() it in all the places where it's read. Pick-to: 6.5 Fixes: QTBUG-112946 Change-Id: I24dc4008fb7eab38e4d24e70211c22e46f1b72a7 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

* Allow AOT functions to signal an undefined result via the contextUlf Hermann2021-06-151-0/+5
| | | | | | | | | | | | undefined as value returned from bindings has the special meaning of resetting the binding. As AOT-compiled functions return the actual type of the binding rather than a QV4::Value, we cannot always encode undefined. Therefore, add a flag that tells us whether the result was supposed to be undefined.

* Optimize stack frame setup for AOT compiled functionsUlf Hermann2021-03-231-58/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When called via the metaobject system, parameters and return values are passed as void*, with accompanying type information in the form of QMetaType. The same format is expected when calling an AOT compiled function. Previously, we would first convert all the parameters to QV4::Value, just to convert them back the moment we notice that there is an AOT compiled function. This is wasteful. This change provides a second call infrastructure that accepts void* and QMetaType as parameter and return value format, and passes them as-is all the way to any AOT compiled functions. If there is no AOT compiled function, the conversion is done when detecting this, rather than when initiating the call. This also passes the information "ignore return value" all the way down to the actual function call. If the caller is not interested in the return value, we don't have to marshal it back at all. For now, we only add the extra "callWithMetaTypes" vtable entry to ArrowFunction. However, other callables could also receive variants optimized for calling with void*/int rather than V4 values. This required changing the way how function arguments are stored in the property cache. We squeeze the return type into QQmlPropertyCacheMethodArguments now, and we use QMetaType instead of integers. In turn, we remove some unused bits. Change-Id: I946e603e623d9d985c54d3a15f6f4b7c7b7d8c60 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

We initialize such variables with the empty value when entering their scope and check upon access for that. For locals we place the lexically scoped variables at the end. For register allocated lexical variables we group them into one batch and remember the index/size. Change-Id: Icb493ee0de0525bb682e1bc58981a4dfd33f750e Reviewed-by: Lars Knoll <lars.knoll@qt.io>
