            Bug ID: 109725
           Summary: [14 Regression] ICE: RTL check: expected code
                    'const_int', have 'reg' in riscv_print_operand, at
                    config/riscv/riscv.cc:4430
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: build, ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zsojka at seznam dot cz
  Target Milestone: ---
              Host: x86_64-pc-linux-gnu
            Target: riscv64-unknown-linux-gnu

RTL checking might need to be enabled.
This currently breaks build with RTL checking enabled.

Compiler output:
