Is there something special to do in order to turn on the use of tablegen patterns for fast-isel.
I know that we are generating the fast-isel files for mips.
it gets a :
FastISel miss: %add = add nsw i32 %1, %0
But we have the underlying structure for this.
I.e. i can assign literals to int globals and such.
And we have the pattern for matching "add".
Is there an easy way to trace this?
