            Bug ID: 110951
           Summary: [13/14] RISCV: rv32 newlib gcc.c-torture testsuite
                    fails with xgcc: fatal error: Cannot find suitable
                    multilib set for
                    '-march=rv32imafdc_zicsr_zifencei'/'-mabi=ilp32d'
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ewlu at rivosinc dot com
  Target Milestone: ---

Seeing the following error on newlib rv32 builds for most (all?)
gcc.c-torture/execute tests without the dg directives (for example,
gcc.c-torture/execute/20031020-1.c).

Error message: xgcc: fatal error: Cannot find suitable multilib set for
'-march=rv32imafdc_zicsr_zifencei'/'-mabi=ilp32d'
results in a compilation failure

Confirmed that the error exists on gcc-13.2.0 and gcc-14.
