Let's go with that, then.
Well, I did play around with that option originally, but temporaries do
not end up in the symbol table, so we won't see them to feed them to
late_global_decl.
We'd have to save them on the side to make them survive until late and
then feed them to late_global_decl separately (which I'm sure Richi will
hate), or we could drill down through the array type/domain to find the
gimple register (which now has an early DIE) and call late_global_decl
on it. However, this last option sounds like a variant of my original
idea-- fill the bound location later, with the unfortunate side-effect
of having an additional DIE (the gimple register DIE).
I guess we could iterate through all the gimple registers late that have
DECL_IGNORED_P == NULL and call late_global_decl on them, but I dislike
this as well. Actually, all ideas involving generating DIEs for
temporaries involve an additional DIE we wouldn't otherwise get.
Can I clean up my original idea instead?
