  "message": "Initial iree_loop_t implementation for web browsers. (#11204)\n\nThis is the start of an implementation of the\r\n[`iree_loop_t`](https://github.com/iree-org/iree/blob/main/runtime/src/iree/base/loop.h)\r\ninterface (added back in https://github.com/iree-org/iree/pull/8329) for\r\nweb browsers, using `setTimeout()`, Promises, and other JavaScript APIs\r\nfor working with asynchronous operations and the browser event loop.\r\n\r\nThis only handles `IREE_LOOP_COMMAND_CALL` for now, but I\u0027d like some\r\nfeedback on the architecture / implementation style.\r\n\r\nSome details that were tricky to figure out:\r\n* This uses a JavaScript library that implements a C API:\r\nhttps://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html#implement-a-c-api-in-javascript.\r\nWe may end up with a few of these.\r\n* The JavaScript library uses `dynCall_iiii` to call a provided C\r\nfunction pointer (I haven\u0027t found any dedicated documentation on this,\r\nso this was pieced together from reading through Emscripten\u0027s source\r\ncode)\r\n* A new `iree_link_js_library` CMake function was added to pass\r\n`--js-library` to `emcc` and set up the right dependency link between\r\n.js files and binaries (tests/applications/etc.). We can also use\r\n`--pre-js` and `--post-js` as needed.",
