...D=4]
And map it to a load.idx instruction with the following semantics:
load.idx r1,r2,r3,SIZE r1 <- mem[r2 + (r3 << sizeof(operand))]
That somehow the pattern matching dag fragment would need to be something
like I had in ADDR_SHLI definition:
def ADDR_SHLI : Addr< 2, "SelectAddrShlImm",
(ops GPRC:$base, ( shl GPRC:$offsetreg, (i64 3))) >;
Now If I have to create a subclass of Operand and define it's EncoderMethod
in C++, does that mean the pattern matching (matching the shift left and
add) now happens on the C++ side as well?
