[LLVMdev] [TableGen] How to specify multiple types to one register class.
...ctly
specify the type of this register class. For now, its type is
specified as i32, and
it is problematic if it is used in floating point instructions, since
tablegen cannot
correctly infer the type information of such a pattern. Here is an example:
// Definition of the register class
def RegCRF : RegisterClass<"Foo", [i32], 32, (sequence "R%u", 0, 255)>;
// Tablegen: error: In FADD: Type inference contradiction found
// no floating point types found
def FADD : InstFoo<(outs RegCRF:$d),
(ins RegCRF:$a, RegCRF:$b),...
