fitzgen edited PR #5975 from explorer to main:

This implements Godbolt Compiler Explorer-like functionality for Wasmtime and Cranelift. Given a Wasm module, it compiles the module to native code and then writes a standalone HTML file that gives a split pane view between the WAT and ASM disassemblies.

THIS IS VERY MUCH AN MVP!!! Tons of stuff we could do with this, very little it actually does so far.

Usage:

$ wasmtime explore test.wasm -o test.explore.html
$ xdg-open test.explore.html

Once visiting the HTML page, you can hover over lines of WAT or asm and the corresponding lines will be highlighted. You can also click to scroll the corresponding line into view.

Here is a little screen recording, although the mouse itself isn't captured so it is a little hard to see what is going on:

If you can get the TargetIsa here, we have a to_capstone method you can use instead of hard-coding that you want an x86 disassembler.

You already mentioned it but I want to specifically highlight this change as needing to be reverted before this PR can merge.

Unfortunately we don't have access to the TargetIsa here, but I did add the non-x86 cases.
