Using `smullohi` in TableGen patterns
> As far as I know, you cannot define a tablegen pattern with multiple
results, and need to use C++ matching. I’m kind of surprised there are
defined td nodes for these.
Yes they were added a while ago, but never used.
If I write a C++ matcher, will the register allocator work correctly? The
multiplication instruction I'm working with always writes the result to
registers `R1` and `R0`,
