Hi,
I can't find a way to define a subregister in a MI, while using another subregister in the same MI.
For example:
reg:low = OP reg:hi, rhs
I really need the reg:low to be part of the same register as reg:hi, but when I use REG_SEQUENCE, this does not happen - I instead get
regC = OP reg:hi, rhs
reg:low = regC
This is not good enough for me. What should I do?
