The objects that the raw pointers point to can be deallocated and new objects can be allocated at the same address, all while these pointers are still in the cache. This can lead to unexpected behavior, for example to calculated bound conflicts with previously cached values. Caching PrimExpr will prevent the objects from being deallocated while the cache is active.
* [WEB] Remove the old web runtime
* [WEB][RUNTIME] TVM WebAssembly Runtime
This PR introduces a brand new TVM web runtime based on the WASM standard API.
Main highlights:
- The new runtime is rewritten using the Typescript.
- The new runtime now directly interfaces with WebAssembly's standard API,
instead of relying on emscripten's API.
This change will make the js runtime more portable to runtime variants.
For example, we could also try to make it interface with the tvm's rust runtime implementation.
- System library can be provided through WASI
- We also build a hack to enable Emscripten to generate a WASI like
bundle for runtime environment on the Web.
- The wasm generation now uses the mainlin LLVM.
- Dynamic link(dlopen) is not used due to limitation of wasm,
instead we rely on the recent new RPC refactor to directly
restart a new session for each wasm binary sent to the RPC.

…pache#5535) * Changes to cpp_rpc to make it work on Android (+ Hexagon offloading) - Implement getNextString to break up std::string into words. stringstream just doesn't work on Android. - string::find_last_of doesn't look for the last substring, but the last character from a given string. - Use SIGTERM to terminate processes (this isn't necessary, but using SIGKILL is not a good practice). - Convert "./rpc" to a full path. When a module is uploaded and offloaded to Hexagon, the dlopen on Hexagon needs an absolute path (or a path without directories). * Only set the absolute patch on non-Windows platforms Windows has different macros for the maximum path length.
* [CRT]fix to reduce RAM size during loading model * Release graph_json memory immediately after reading
* [RPC] Improve RPCServer AsyncIO support. When the RPCServer is in the async IO mode, it is possible for the server to directly serve async function that may return its value via a callback in the future. This mode is particular useful to the web environment, where blocking is not an option. This PR introduces the Async support to the RPCSession, allowing the AsyncIO driven servers to serve the async functions. These functions will still be presented as synchronized version on the client side. Followup PR will refactor the web runtime to make use of this feature. * Address comments

…e#5546) modified to run specifically on ARM cortex-M hardware, which currently is just the STM32F746 discovery board. Signed-off-by: Tom Gall <tom.gall@linaro.org>
This PR introduces WebGPU support to tvm. The WebGPU runtime is directly built in javascript(as WebGPU uses JS as the first class citizen API) and exposes back to the tvm's runtime via PackedFuncs. One important note is that `ctx.sync` is not async. This is due to the fact that WebGPU is a purely async API and we cannot block in the web environment. So the current best way to use the js api is to wrap things in an async function. When copy a GPU array to CPU, `await ctx.sync()` need to be called to wait for copy completion. We use a AsyncIO rpc server to serve the async functions to the clients.

* edit onnx parser to infer values in post order to speed up onnx imports with many calls to infer_value * fix pylint
* support aten::type_as in the pytorch frontend * use _convert_data_type to convert torch type to tvm type and add more types in the type_as test
This PR updates the remaining TIR node's member to use String instead of std::string.
* [ONNX] Skip ADD inside Gemm op when vector is zero * [ONNX] Skip multiply with 1.0f constant for GEMM import
* Versions above 0.7.4 are broken due to changes in the quantization operations in the model, which are current not supported by TVM. Fixes apache#5774.

Changes made on top of cherry-picks:
module.is_empty()code - we added this to neo-ai/tvm for nnvm-trt integration which is no longer needed.
