[LLVMdev] How to partition registers into different RegisterClass?
...typedef two packed classes: [4 x float] and [4 x int], and add an
enum 'packed' to MVT::ValueType (ValuesTypes.h).
I declared all 'RegisterClass'es to be 'packed' (first argument of
RegisterClass):
def GeneralPurposeRC : RegisterClass<packed, 128, [R0, R1]>;
def INT_ReadOnlyRC : RegisterClass<packed, 128, [I0, I1]>;
def FP_ReadOnlyRC : RegisterClass<packed, 128, [F0, F1]>;

[LLVMdev] How to partition registers into different RegisterClass?
Hi, everyone.
I' have three set of registers - read-only regs, general purpose regs
(read and write), and write-only regs. How should I partition them
into different RegisterClasses so that I can easy define the
instruction?
All RegisterClasses must be mutally exclusive. That is, a register can
only be in a RegisterClass. Otherwise TableGen will raise an error
message.
