jameysharp opened PR #8949 from jameysharp:inline-get-wasm-trap to bytecodealliance:main:

In the past, the wasmtime-runtime crate couldn't directly call get_wasm_trap because the registry of loaded modules was in the wasmtime crate, so it called through a global function pointer registered with init_traps instead.

Since the two crates were merged in #8501, we no longer need this indirection.

While I'm here, I've also split the former get_wasm_trap function into two parts: lookup_code finds a loaded module that had been previously registered with register_code, and the lookup_trap_code step is now done by a helper on CodeMemory. This makes the module registry more broadly useful.

I also simplified the code lookup step in two ways:

• I removed a redundant check from the code lookup. BTreeMap::range will only return entries where end >= pc, so the end < pc condition is always false.
• I used checked_sub instead of writing both the comparison and subtraction explicitly.
