--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> --- Working on that I've just noticed Richi that gcc/doc/invoke.texi contains: 9485 Link-time optimization does not work well with generation of debugging 9486 information. Combining @option{-flto} with 9487 @option{-g} is currently experimental and expected to produce unexpected 9488 results. Now having early-lto debug info, would you change it?
