* broadcom: Add V3D 3.3 QPU instruction pack, unpack, and disasm.Eric Anholt2017-10-101-0/+0
Unlike VC4, I've defined an unpacked instruction format with pack/unpack functions to convert to 64-bit encoded instructions. This will let us incrementally put together our instructions and validate them in a more natural way than the QPU_GET_FIELD/QPU_SET_FIELD used to. The pack/unpack unfortuantely are written by hand. While I could define genxml for parts of it, there are many special cases (like operand order of commutative binops choosing which binop is being performed!) and it probably wouldn't come out much cleaner. The disasm unit test ensures that we have the same assembly format as Broadcom's internal tools, other than whitespace changes. v2: Fix automake variable redefinition complaints, add test to .gitignore
