            Bug ID: 16655
           Summary: restore.exp, store.exp failures in testsuite
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dje at google dot com
              Host: amd64-linux
            Target: amd64-linux

This bug is to track these failures (introduced by gcc changes IIRC).

I'm seeing a lot of gdb.bases/restore.exp failures on arm-none-eabi with
-mthumb.  I believe the problem is 

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62225

GCC is not emitting DW_AT_location information for the variables it is
complaining about without -fvar-tracking enabled.
