cfallin opened PR #2410 from x64-gc to main:

One critical bit of plumbing was missing: the StackMapSink passed to
compile_and_emit was not actually receiving stackmaps. This seemingly
very basic issue was not caught because the other major user of reftype
support, SpiderMonkey, extracts stackmaps with a lower-level API. The
SM integration was built this way to avoid an awkward API quirk when
passing stackmaps through a CodeSink that proxies them to a
StackMapSink: the CodeSink wants Values for each reference slot,
while the actual StackMapSink does not require these. This PR tweaks
the plumbing in a slightly different way to make wasmtime GC tests,
and presumably other consumers of stack-map info from the top-level
Cranelift interface, happy.
