            Bug ID: 99860
           Summary: RFE: analyzer does not respect "restrict"
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

The analyzer currently is very conservative about aliasing, and assumes that
anything that could be aliased by a pointer gets clobbered when a write occurs
through that pointer.

Am filing this bug to remind me to better support pointers marked with
"restrict".

Probably should also warn about places where the analyzer detects that restrict
isn't being honored.=
