--- Comment #7 from Cary Coutant <ccoutant at gcc dot gnu.org> --- (In reply to Andres Freund from comment #2) > The point is that this has changed between 4.8 and 4.9... And I don't > see anything relevant in http://gcc.gnu.org/gcc-4.9/changes.html Yes, you're right. This change should have been documented there. Sorry! I did ask twice for consensus, and got no objections either time. Our build system adds -g1 to the compile options, before user-supplied options, and if a user adds -g, it's surprising to only get -g1. I wonder if it would be reasonable for -g to set the debug level to max(2, previous level)? I still think the simplicity of -g === -g2 is much better, and it's also much better to be consistent with the -O option. What should the following combinations do? -g1 -g -g1 -g0 -g -g3 -g -g3 -g0 -g -cary
