I must say I'm surprised by the gimple-fold.c test, I'd really expect

additional && DECL_VISIBILITY (decl) != VISIBILITY_DEFAULT .

Another alternative to make those always hidden (which could be an exported ABI

change for some shared libraries, though unlikely to be actually a real

problem) would be to add some new bit, either in the tree itself, or better in

symtab

node, which would tell gimple-fold.c not to optimize it.  Honza?
