I've always wanted to make us compare the actual binaries now that the checksums do not cause miscompares... of course linker behavior will then factor in and I'm not sure how reliable such compare would be. And yes, at the moment we _do_ compare LTO bytecode... (which obviously will fail with -g vs. -g0) Richard. > -- > Markus
