Yes it supports both BFI_INT and BIT_ALIGN (rotate). The GCN architecture is very different to the VLIW ones. GCN is a scalar data architecture while VLIW was a vector data architecture. Currently the only source to find more about GCN is to watch the ISA dumps. AMD did not give out any specs or documentation on the instruction assembly yet.
