Hi,
As it turns out, c-decl.c doesn't need to copy GIMPLE bodies anymore,
since gimplifications happens unit-at-a-time now, and pushdecl is
never called for GIMPLE functions after that.
Bootstrapped&tested on x86_64-unknown-linux-gnu. More importantly:
Tested a different patch that had "gcc_assert (! gimple_body
(...decl))" instead of the gimple_set_body calls. Just to make
absolutely sure there really never is a GIMPLE body.
OK for trunk?
Ciao!
Steven
* c-decl.c: Don't include gimple.h.
(merge_decls): Do not copy gimple_body.
