6.6.1.9 -mno-errata=id[,id]*

This option disables specific errata workarounds identified by id. Valid values for id change from time to time. This is particularly useful when specifying errata with -merrata=all as it can be used to disable some errata that are not required. -mno-errata=foo will prevent the erratum foo from being enabled no matter where it appears on the command line. Therefore, -mno-errata=foo -merrata=foo will not enable erratum foo.
