function (qt_internal_setup_wasm_target_properties wasmTarget)
wasm: don’t set exit_runtime Go with Emscripten’s default of not shutting down on main() exit; this allows for writing main() in such a way that avoids the exec() workaround. Existing main() implementations (which do use the exec() workaround) do not shut down Qt cleanly anyway, so we gain little by shutting down the Emscripten runtime. Applications can set this flag if they do want to shut down on main() exit: LFAGS += -s EXIT_RUNTIME=1 Change-Id: I52e1cc2bc907d1d2146822713e39b7610db3f95b Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io> Reviewed-by: Lorn Potter <lorn.potter@gmail.com>

wasm: enable WASM_BIGINT JavaScripts's BigInt feature provides support for arbitrary-precision integers. This makes it possible to represent 64-bit integers; the standard JS Number type supports 32-bit integers only (or more accurately 53-bit integers - see Number.MAX_SAFE_INTEGER). Enable WASM_BIGINT which makes Emscripten map int64_t and uint64_t to BigInt when interfacing with JavaScript code. This removes one of the conditions which enables wasm-emscripten-finalize.

wasm: enable MODULARIZE option and set EXPORT_NAME Make Emscripten generate a global constructor function ("createQtAppInstance()") instead of a global javascript module object. This enables more fine-grained control over module instantiation; previously the module object would be created when the runtime javascript was evaluated, and the number of emscripten module/instances was limited to one per page. Set EXPORT_NAME to “createQtAppInstance” which avoids collisions with other non-Qt Emscripten modules on the same page. A further improvement would be to include the app name in EXPORT_NAME, but this is not done at this time. Update the code in qtloader.js to call the constructor function instead of working on a global module object. The qtloader.js API is functional before the wasm and Emscripten modules have been instantiated; store properties and forward to the Emscripten module when it's created.

wasm: enable event dispatcher asyncify support Misc. fixes, including: Fix a couple of typos in the JavaScript code. Also, macros- within-macros don’t work, (without resorting to preprocessor token pasting), so remove the debug output for now. Limit the exec() “simulateInfiniteLoop” workaround to top-level application exec() only. This way, asyncify can be used for nested QEventLoop::exec() calls. (Emscripten supports one level of suspend only, so we don’t want to use that for the top-level exec(), but instead use it for dialogs and such). Use the new QEventLoop::ProcessEventsFlag::ApplicationExec enum value to detect the exec() call type.
