--- Comment #19 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Chengnian Sun from comment #18) > Hello folks, > > While testing gcc with -fcompare-debug, I was asked a question which puzzled > me as well. > > What if we always enable -g, and use 'strip' to remove debug information > from the binary file? Then we do not need to pay much attention to bugs > detected by -fcompare-debug. because -g has a compile time overhead and even an assembler time overhead; in some cases the debugging informationg is huge even for small programs. Plus there are different levels of -g: -g1, -g2, and -g3 (-g is the same as -g2). So which one would you enable by default?
