tablegen exponential behavior
Hi,
I implemented a pattern matching of the dot product for arm64
and it seemed to work well for the basic case, i.e.,
class mulB<SDPatternOperator ldop> :
PatFrag<(ops node:$Rn, node:$Rm, node:$offset),
(mul (ldop (add node:$Rn, node:$offset)),
(ldop (add node:$Rm, node:$offset)))>;
class mulBz<SDPatternOperator ldop> :
PatFrag<(ops node:$Rn, node:$Rm),
(mul (ldop node:$Rn), (ldop node:$Rm))...
