--- Comment #1 from David Blaikie <dblaikie at gmail dot com> --- So DWARFv5 added a zeroth entry to the line table (used to be the line table started at 1). GCC produces two entries even for a simple file - a zeroth and a first, both with the same value, and GCC always use the first. Clang produces one entry and uses that. Looks like objdump is ignoring/marking the zeroth as "unknown" - if you add a #line to the source so that Clang uses that as a first entry (after the zeroth original entry) then objdump behaves fine. So, yeah, missing zeroth entry in DWARFv5 (now that it has zeroth entries) somewhere in objdump. -- You are receiving this mail because: You are on the CC list for the bug.
