Do you mea
Yes, I agree long-term we want every-thing be optimized as early as possible.
However, IMHO, it's impossible we can support every conditional patterns in the
middle-end (match.pd).
It's a really big number.
For example, for sign_extend conversion, we have vsext.vf2 (vector SI -> vector
DI),...
