[PATCH 08/44] RISC-V: Simplify EQ vs NE selection in `riscv_expand_conditional_move'

[Maciej W. Rozycki]

Just choose between EQ and NE at `gen_rtx_fmt_ee' invocation, removing 
an extraneous variable only referred once and improving code clarity.

        gcc/
        * config/riscv/riscv.cc (riscv_expand_conditional_move): Remove 
        extraneous variable for EQ vs NE operation selection.
---
FWIW I have no idea what "We need to know where so that we can adjust it 
for our needs." refers to, but that would have to be for another change.
