Michael C

. Old Bugs Fixed

  Jason M fixed a bug in gcc HEAD, pr gcc/9039.  The bug had been
  causing an internal compiler error in anon-union.exp with gcc HEAD
  -gdwarf-2.

  Andrew C fixed a bug in gdb where gdb caused a SIGFPE in the target
  program.

  . Counts

    gdb 5.3:             0 test aborts, 381 non-PASS results
    gdb HEAD:            0 test aborts, 390 non-PASS results

    A non-PASS result is any result except PASS.  This includes ERROR,
    WARNING, NOTE, FAIL, KPASS, KFAIL, XPASS, XFAIL, UNRESOLVED,
    UNTESTED, UNSUPPORTED, and unknown results.

  . 5.3

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

	pr gdb/544: gdb.c++/annota2.exp: annotate-quit test sometimes fails
	http://sources.redhat.com/cgi-bin/gnatsweb.pl?database=gdb&cmd=view&pr=544

	Fluctuation in test result probably due to a signal handling
	race in the command loop.

    . gdb.c++/anon-union.exp: *
	ERROR -> null
	WARNING -> null
	UNRESOLVED -> null
	null -> PASS
	null -> FAIL

	Jason M fixed a bug in gcc HEAD, pr gcc/9039.  The bug had been
	causing an internal compiler error in anon-union.exp with gcc
	HEAD -gdwarf-2.

    . gdb.c++/classes.exp: ptype struct default_public_struct
	UNRESOLVED -> XFAIL

	This was a cascade problem from anon-union.exp.

    . gdb.threads/killed.exp: GDB exits after multi-threaded program exits messily

	pr gdb/568: GDB confused by messily-exiting multi-threaded programs
	http://sources.redhat.com/cgi-bin/gnatsweb.pl?database=gdb&cmd=view&pr=568

	Jim B thinks that this test may depend on a race condition:

	  http://sources.redhat.com/ml/gdb-testers/2002-q4/msg00010.html

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

	pr gdb/544: gdb.c++/annota2.exp: annotate-quit test sometimes fails
	http://sources.redhat.com/cgi-bin/gnatsweb.pl?database=gdb&cmd=view&pr=544

	Fluctuation in test result probably due to a signal handling
	race in the command loop.

    . gdb.threads/schedlock.exp: *

	This test script is useless in this release because of a
	signed-versus-unsigned bug.

	Daniel J has an obvious fix, which has been applied to gdb HEAD:

	  http://sources.redhat.com/ml/gdb-patches/2002-10/msg00454.html

  . HEAD

    checkout date is '2003-03-25 17:06:46 UTC'

    . gdb.base/return2.exp: *
	ERROR -> null
	FAIL -> null
	null -> PASS
	FAIL -> PASS
	UNRESOLVED -> PASS

	Andrew C fixed a bug in gdb:

	  http://sources.redhat.com/ml/gdb-patches/2003-03/msg00352.html

    . gdb.base/watchpoint.exp: continue to breakpoint: second x assignment
      gdb.base/watchpoint.exp: watch x
	null -> PASS
      gdb.base/watchpoint.exp: next after watch x
	null -> KFAIL

	David C wrote a new test for pr gdb/38.

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

	Same analysis as 5.3.

    . gdb.c++/anon-union.exp: *

	Same analysis as 5.3.

    . gdb.threads/killed.exp: GDB exits after multi-threaded program exits messily

	Same analysis as 5.3.

    . gdb.threads/schedlock.exp: *

	Two guys are in their driveway working on a car.  The guy inside
	the car says: "tell if me the turn signal is working now." The
	guy standing behind the car says: "It's working ... it's not
	working ... it's working ... it's not working."

	This test is still in a state where it's better to analyze the
	absolute results than to compare results from date to date.

. Test Matrix

  target     => native
  host       => i686-pc-linux-gnu
  osversion  => red-hat-8.0
  gdb        => 5.3, HEAD%20030325
  gcc        => 2.95.3, 3.2-7-rh, 3.2.2, gcc-3_2-branch%20030324, gcc-3_3-branch%20030324, HEAD%20030324
  binutils   => 2.13.90.0.2-rh, 2.13.2.1, HEAD%20030324
  glibc      => 2.2.93-5-rh
  gformat    => dwarf-2, stabs+
  glevel     => 2
  count         64 = 1 * 1 * 1 * 2 * (5*3+1*1) * 1 * 2 * 1

  'target' and 'host' are gnu configuration triples.

  'osversion' is the host operating system name, which is additional
  information beyond 'host'.

  'gdb', 'gcc', 'binutils', and 'glibc' are version names.

  versions starting with a digit are official releases or snapshots.
  versions starting with a digit and ending with '-rh' are
    vendor-supplied official releases on my red hat linux host.
  versions named 'HEAD' are the cvs HEAD, also known as 'mainline' or 'trunk'.
  versions with any other name are cvs branches.
  cvs versions (head and branch) show the checkout date after a '%' delimiter.

  'gformat' is the debugging information format.
  'glevel' is the debugging level.

  'count' is the total number of configurations tested.
  The vendor gcc is available only with vendor binutils,
    thus the '(5*3+1*1)' term for gcc/binutils combinations.

. Baseline software

  . host=i686-pc-linux-gnu, osversion=red-hat-8.0

    make 3.79.1
    binutils 2.13.2.1
    gcc 3.2.2
    flex 2.5.4
    bison 1.875
    tcl 8.4.1
    expect 5.38.0
    dejagnu 1.4.3

    The sources.redhat.com cvs repository has its own versions of tcl,
    expect, and dejagnu.  I don't have the resources to test with both
    tcl/expect/dejagnu stacks, so I choose the stock stack for my test
    bed.

    The sources.redhat.com version of tcl is nearly identical to tcl
    8.4.1.  The sources.redhat.com version of expect dates from
    1998-06-15.  The sources.redhat.com version of dejagnu is nearly
    identical to dejagnu 1.4.3.

    I have packaged and published my scripts to manage the baseline
    software.  They are called Migchain (Michael's Gnu Toolchain),
    and they are licensed under the GPL.
