[pushed] c++: remove nsdmi_inst hashtable
Checks
Commit Message
Tested x86_64-pc-linux-gnu, applying to trunk.
-- 8< --
It occurred to me that we have a perfectly good DECL_INITIAL field to put
the instantiated DMI into, we don't need a separate hash table.
gcc/cp/ChangeLog:
* init.cc (nsdmi_inst): Remove.
(maybe_instantiate_nsdmi_init): Use DECL_INITIAL instead.
