Using -> to dereference a struct is incorrectly complaining that it is
being applied to a declared but not defined struct, when the struct in
question is first forward declared:
test.ispc:21:5: Error: Member operator
"->" can't be applied to
declared but not defined struct
type "uniform struct A".
b.mA->mX = 3;
^^^^^^^^
This is using ispc-1.9.2. Is this a known issue? Am I incorrectly
thinking that this should work? The example below may look a little
contrived, in practice we are hitting this issue when the forward
declaration takes place in header files and the definition is only brought
into the needed compilation units.
Cheers,

----- test.ispc
// forward declaration of A
struct A;
struct B
{
uniform A * uniform mA;
};
// definition of A
struct A
{
int mX;
};
export void
run()
{
B b;
// BUG: this does not compile ???
b.mA->mX = 3;
// but this is fine
// uniform A * uniform a2 = b.mA;
// a2->mX = 3;
}
