gnu_debuglink uses the CRC to confirm that a standalone debug file (e.g. library.so.debug) matches the binary or library, and needs to be calculated only for those debug files. In fact, prior to the gnu_debuglink support I think ELF files all ended up with an all-0s UUID. I think your change is a reasonable first step. -Ed _______________________________________________ lldb-dev mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/lldb-dev
