| # Test that BOLT can handle CIE's produced by GNU as. On RISC-V, GNU as produces |
| # the following initial instruction: |
| # DW_CFA_def_cfa_register: r2 |
| # While I believe it is technically incorrect to use this instruction without |
| # first using a DW_CFA_def_cfa (since the offset is unspecified), both readelf |
| # and llvm-dwarfdump accept this and implicitly set the offset to 0. |
| # In BOLT, this used to trigger an assert, however, since it (correctly) |
| # believed the offset was not set. This test checks we can handle this |
| # situation. |
