Topic: wasmtime / PR #11338 Fix calculation of reachable DWARF

philipc opened PR #11338 from philipc:dwarf-reachable to bytecodealliance:main:

A single dependency graph indexed by gimli::UnitSectionOffset was used to contain the dependencies from every gimli::Dwarf. However, this is not correct because a gimli::UnitSectionOffset is only unique within its associated gimli::Dwarf.

Fix by using one graph per gimli::Dwarf.

In addition to wasmtime's tests, the only testing I have done on this is to compile the component-docs tutorial using wasmtime and diff the resulting DWARF. That diff showed that this patch does affect which DWARF entries are determined to be reachable.
