    . Notes

      target and host names are gnu triples with extra information after
      a '%' delimiter.

      versions which start with a number are official releases or snapshots.
      versions named "HEAD" are the cvs HEAD.
      versions with any other name are cvs branches.
      cvs versions show the pull date after a '%' delimiter.

      gdb 5.2 is a prerelease (gdb-5.1.92.tar.bz2).

      gcc releases and snapshots are built with binutils 2.11.2

      gcc cvs versions are built with binutils HEAD with the same pull date.

      . Overview

        gdb 5.1.1:           0 build aborts, 0 test aborts, 635 attention lines
        gdb 5.1.91:          0 build aborts, 0 test aborts, 457 attention lines
        gdb 5.2:             0 build aborts, 0 test aborts, 457 attention lines
        gdb gdb_5_2-branch:  0 build aborts, 0 test aborts, 457 attention lines
        gdb HEAD:            0 build aborts, 0 test aborts, 266 attention lines

        An attention line is a line with one or more attention results.

        An attention result is any result except PASS.  This includes
        ERROR, WARNING, FAIL, KPASS, KFAIL, XPASS, XFAIL, UNRESOLVED,
        UNTESTED, UNSUPPORTED, and unknown results.

      . Old bugs fixed

        Two FAILs in gdb.base/gcore.exp were fixed in gdb HEAD.

      . New bugs detected

        None.

. Test protocol changes since last report.

  I added gdb 5.2.  This report, gdb 5.2 is a prerelease version which comes
  in a tarball named gdb-5.1.92.tar.bz2.  I treat it as gdb 5.2.  Thus,
  next report, I will have "compare against date" for 5.2.

    . 5.1.1

      No significant changes.

    . 5.1.91

      No significant changes.

    . 5.2

      This is the first report for gdb 5.2.
      I compared gdb 5.1.91 versus gdb 5.2 and found no significant changes.

    . gdb_5_2-branch

      No significant changes.

        . Gdb Improved

          gdb.base/gcore.exp: corefile restored all registers
          gdb.base/gcore.exp: corefile restored general registers

            Gdb improved.

        . Noise

          . gdb.c++/annota2.exp: annotate-quit

            This test is unstable.

          . gdb.c++/local.exp: ptype InnerLocal::NestedInnerLocal (gdb/482)
            gdb.c++/local.exp: ptype Local (gdb/483)
            gdb.c++/method.exp: print this in A::bar (gdb/277)

            The test script changed to show the gnats pr number.
