- Subject: [PATCH] Fixup canonicalize_constructor_val some more
Make sure to mark decl addresses coming from constructors
as addressable (otherwise early folding fails for all java testcases).
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.
Richard.

* gimple-fold.c (canonicalize_constructor_val): Mark
address-taken variables addressable.
