sunday project report, gdb, 2002-05-05

[Michael Elizabeth Chastain <mec at shout dot net>]

For the third straight report, there are no regressions in any configuration.

The new test gdb.c++/hang.exp crashes gdb on native i686-pc-linux-gnu with
gcc 3.0.4 -gdwarf-2.  This is pr gdb/532.

I am planning to drop gdb 5.1.1 in the next report.
All hail 5.2!

    . 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.

      gcc releases and snapshots are built with binutils 2.11.2

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