// This file declares the FixRISCVCallsPass class, which replaces all types of
// calls with PseudoCALL pseudo instructions. This ensures that relaxed calls
// get expanded to auipc/jalr pairs so that BOLT can freely reassign function
// addresses without having to worry about the limited range of relaxed calls.
// Using PseudoCALL also ensures that the RISC-V backend inserts the necessary
// relaxation-related relocations to allow JITLink to relax instruction back to
// shorter versions where possible.
