Remove Cxxx registers, add new special register - "ALU_CONST" and new operand for each alu src - "sel". ALU_CONST is used to designate that the new operand contains the value to override src.sel, src.kc_bank, src.chan for constants in the driver. Patch by: Vadim Girlin Vincent Lejeune: - Use pointers for constants - Fold CONST_ADDRESS when possible Tom Stellard: - Give CONSTANT_BUFFER_0 its own address space - Use integer types for constant loads Reviewed-by: Tom Stellard <thomas.stellard@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173222 91177308-0d34-0410-b5e6-96231b3b80d8
