# 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.
