Bug ID: 70613 Summary: -fabi-version docs don't match implementation Product: gcc Version: 5.3.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: wilson at gcc dot gnu.org Target Milestone: --- In docs/invoke.texi, it says that 8 is the highest value for -fabi-version. In c-family/c-opts.c, flag_abi_version gets set to 9. I see two places that check for abi_version of 9 in cp/class.c. And one place in cp/decl.c. At first glance it appears that this is just a documentation bug. I haven't verified this yet. Since gcc-5 is the first version that defaults to -fabi-version=0, we really should get the -fabi-version docs correct.
