            Bug ID: 95006
           Summary: Reimplement -Wanalyzer-use-of-uninitialized-value
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: meta-bug
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
        Depends on: 94447, 94639, 94732, 94754
  Target Milestone: ---

I removed -Wanalyzer-use-of-uninitialized-value in
r10-8012-g78b9783774bfd3540f38f5b1e3c7fc9f719653d7 as it had too many false
positives:
  https://gcc.gnu.org/pipermail/gcc-patches/2020-April/544726.html

This is a tracker bug, for keeping track of what needs fixing in order to
reimplement it.
