--- Comment #1 from Joel Rosdahl <joel at rosdahl dot net> --- I've now had a brief look at the DWARF-5 specification. The notes on lines 6-11 on page 156 seem to imply that the intention of 0'th entry is to be a copy of DW_AT_comp_dir. Another data point is that Clang in Fedora 34 sets the 0'th directory entry with -fdebug-prefix-map applied. -- You are receiving this mail because: You are on the CC list for the bug.
