Description
property var v: null
Component.onCompleted: {
var g = null
if (g !== null) {}
}
will fail with a compile error:
/foo/minipdf_main_qml.cpp:223:9: error: expected primary-expression before ‘!=’ token
223 | r2_1 = != ;
| ^~
/foo/minipdf_main_qml.cpp:223:12: error: expected primary-expression before ‘;’ token
223 | r2_1 = != ;
| ^
generated code in the .cpp file looks like this:
extern const QQmlPrivate::AOTCompiledFunction aotBuiltFunctions[] = { { 0, QMetaType::fromType<void>(), { }, [](const QQmlPrivate::AOTCompiledContext *aotContext, void *dataPtr, void **argumentsPtr) { wrapCall(aotContext, dataPtr, argumentsPtr, [](const QQmlPrivate::AOTCompiledContext *aotContext, void **argumentsPtr) { Q_UNUSED(aotContext); Q_UNUSED(argumentsPtr); bool r2_1; // Component.onCompleted: { // generate_CreateCallContext { // var g = null // if (g !== null) {} // generate_CmpStrictNotEqual r2_1 = != ; // generate_JumpFalse if (!r2_1) ; // generate_PopContext ;} // generate_Ret return; });} },{ 0, QMetaType::fromType<void>(), {}, nullptr }}; QT_WARNING_POP } }
