Based on https://github.com/WebAssembly/binaryen/discussions/6225#discussioncomment-8954759 Currently, many Wasm instructions are defined in `src/wasm-delegations*.def`, which is a C header that Binaryen and tools within Binaryen can use. This file could also be processed...

1

I have a somewhat large binary (1.9 mb) that contains a function with a lot of nested if-then-else instructions, and running `wasm-opt -O2 --enable-tail-call --enable-mutable-globals --output ` causes a segmentation...
