(f) A global command-line option, which we check alongside DECL_COMMON and
further tests (basically, we want only DECL_COMMON decls that either have
ARRAY_TYPE, or some other aggregate type with flexible array member or some
other trailing array in the struct), and use the resulting predicate in
places where we optimize based on DECL_SIZE{,_UNIT} of the decl - if that
predicate returns true, we assume the DECL_SIZE is
"variable"/"unlimited"/whatever.
The two spots known to me that would need to use this new predicate would
be:
tree.c (array_at_struct_end_p):
tree-dfa.c (get_ref_base_and_extent):
Well, with just those two, this fixes 416.gamess, and passes all tests in
gfortran, with only a few scan-dump/warning tests failing in gcc...
