Version 3.1 of VisualDSP includes support for C-like struct datatype
for assembler. This supports named offseted indirect access via DAG
pointers of the kind
i0 = MyStruct;
r0 = dm(offsetof(MyStruct, temp1), i0);
where temp1 is a member variable of MyStruct. Look up the exact syntax
for definition and declaration of structs in the manual.

Is there a way to "force" C compiler/linker to produce code that references
C code data variables not by their absolute address, but rather by their
offset from the beggining of the corresponding data section.
Something like :
b0 = start_address_of_data_section;
i0 = offset_for_temp;
r0 = b0 + i0; //r0 holds address of temp
instead of :
r0.l = temp;
r0.h = temp; //r0 holds address of temp
