Compatibility of processors

Hello everyone!

Not so long ago I have got HD 2600XT (RV630) and programming GPU with use CAL/IL became accessible to me. But at viewing of examples from CAL SDK I had some questions. Here one of them. The code of a kernel from an example "global_input_IL" ("global_output_IL" too) in ShaderAnalyzer was successfully compiled only on processor RV670. In the documentation there is a reservation what only processors RV670 can work with global memory but why there was no compilation on RV770, after all it is later processor? Certainly, it is a program complex it is intended for family R600, but unless here there should not be a compatibility?
