commit e75ca7015faf348b25b180168617dd2bef78cfc9

    RISC-V: Avoid repeated GET_MODE calls in `riscv_expand_conditional_move'
    
    Use `mode0' and `mode1' shorthands respectively for `GET_MODE (op0)' and
    `GET_MODE (op1)' to improve code readability.
    
            gcc/
            * config/riscv/riscv.cc (riscv_expand_conditional_move): Use
            `mode0' and `mode1' for `GET_MODE (op0)' and `GET_MODE (op1)'.
    
    (cherry picked from commit 00a3bd4ccae4f7a7fd1d76db325808129208986b)
