10.0pt;font-family:Arial;color:navy'>The problem with that is I still have to
write multiple multipatterns, and in this particular case, I want the pattern
to match all types of the GPR register class, not just a single one of that
class per sub-pattern. The GPR register class has 32bit and 64 bit scalars
along with 32, 64, and 128 bit vector types. So the number of patterns I would
have to write is very large even with a multipattern but the instruction
produces for all of these types is the exact same, “mov g[$ptr], $val”.<o:p></o:p></span></font></p>
