Optimization for using compressed beqz and bnez
If there is pattern
br_cc val1 constval eq/neq place select_cc val1 constval eq/neq trueval falseval
and constval does not fit in compressed imm format(6 bit), but fit in
imm format(12 bit), we can replace by non compress sub and compress
c.beqz/c.bneqz:
addi val val -constval c.beqz val place
