It would be really helpful to have a flag to disable this "note". ^ permalink raw reply [flat|nested] 5+ messages in thread

The various 'inform' notes in i386.cc that depend on warn_psabi should probably output "[-Wpsabi]" to make this clear. ^ permalink raw reply [flat|nested] 5+ messages in thread
