Hm? I said,
There's another issue with handling of types in init_output_initializer.
Test libgomp.c++/examples-4/declare_target-2.C fails with "libgomp: Can't map
target variables (size mismatch)".
Variables varX and varY of struct/class type have size 4, but their
definition
in PTX code has size 8 because init_output_initializer changes 'type' to
ptr_type_node and emits them in size-8 chunks.
Ooops, sorry, somehow that didn't show up. Mailer user interface trouble.
So I did mention the testcase, and the issue: structs with size 4 on host are
emitted with size 8 into PTX code.
Ok, so adjust the if condition for non-integral types - make it false if
the size of the struct is smaller than the pointer type.
