[LLVMdev] Multiclass patterns
Bill,
Sorry if I wasn't clear enough. I wasn't referring to multiclass's that
define other classes, but with using patterns inside of a multiclass to
reduce redundant code.
For example:
multiclass IntSubtract<SDNode node>
{
def _i8 : Pat<(sub GPRI8:$src0, GPRI8:$src1),
(ADD_i8 GPRI8:$src0, (NEGATE_i8 GPRI8:$src1))>;
def _i32 : Pat<(sub GPRI32:$src0, GPRI32:$src1),
(ADD_i32 GPRI32:$src0, (NEGATE_i32 GPRI32:$src1))>;
}
or something similar.
I just want to write the pattern once and...

[LLVMdev] Multiclass patterns
Is there a way to define a multi-class pattern in tablegen?

Yes. See "multiclass" and "defm" in, say, X86Instr64bit.td, et al.
