yowl opened PR #8055 from yowl:dwarf-att-string to bytecodealliance:main:
Wasmtime supports debugging with DWARF, and this PR adds initial support for DWARF fission. DWARF fission has advantages in linking and wasm size (https://developer.chrome.com/blog/faster-wasm-debugging) as it separates the debug_info section into a separate file leaving a
DW_TAG_skeleton_unitin the main wasm file.This PR only supports DWARF pacakges,
.dwpfiles. It should also be possible to support.dwofiles, but I've not done that here.
yowl updated PR #8055.
