gcc12-pr102876.patch
Untested implementation of the optimization.
So far a little bit limited, either it handles initialization of the whole var
at once (usually scalar vars), or uses native_{encode,interpret}*
infrastructure
and in that case it can't handle unions or anything that needs relocations in
the initializers. I guess in some cases it could be improved, but especially
unions can be harder or very hard if the access path is not visible in the
stores.
