                    documented
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

https://gcc.gnu.org/pipermail/gcc-patches/2016-September/457570.html added the
support for them but there is no mention of them in
https://gcc.gnu.org/onlinedocs/gccint/Directives.html#Verify-compiler-messages
.

I noticed this while helping someone write testcases today.
