Verifying Backend Schedule (Over)Coverage
I ran into an interesting problem when helping to land a scheduler .td file
that my colleague had written. The problem that came up was that a
multiply/add pair was not combined into an madd, but just for our CPU. Upon
digging into it, the problem turned out to be that '(instregex "^SUB" ...'
was matching "SUBREG_TO_REG" and incorrectly increasing the schedule length.
