The WebAssembly Pre-Initializer
Given the program ``` package main import "os" var theText string //go:export wizer.initialize func WizerInitialize() { buf, err := os.ReadFile("test.txt") if err != nil { println("error: Cannot read test.txt", err.Error())...
In theory, wizer could support a call to open a listening socket during initialization. The call would get recorded as a listening port, and when the resulting module is later...
Hi all, Not sure whether Wizer is supposed to work with Emscripten. I tried compiling the following c++ code with emcc ``` #include #include #include WIZER_DEFAULT_INIT(); EMSCRIPTEN_KEEPALIVE int SayHello() {...
Before testing that we get the expected result from the following sequence: * initialize+snapshot with Wizer * instantiate the snapshot * call `run` we should test that we get the...
Rather than fully parsing the wasm to validate it via `wasmparser::Validator::validate_all` and then full re-parsing the Wasm *again* inside the `parse` pass when constructing the `ModuleInfo` tree, we should use...
It'd be great if we could easily make the resulting snapshot's size available. For the CLI tool, perhaps just logging it to stdout, but in the embedding API having an...

I am running wizer on a large wasm file with 80390 data segments (I can provide it on request). The file output by wizer does preserve my data segments but...
We just landed a change to StarlingMonkey to support handling the invariants of the monotonic clock by defining an offset based on the difference between the Wizer time monotonic clock...
