Highlights of this report:
. No new bugs detected in gdb or the gdb test suite.
. There are no regressions in the gdb test suite from gcc 3.2.2 to gcc
gcc-3_2-branch%20030227.
. There are several regressions in the gdb test suite from gcc 3.2.2
to gcc gcc-3_3-branch%20030227. Specicially:
gdb=5.3 gformat=stabs+ glevel=2
gdb.c++/inherit.exp
gdb.c++/local.exp
gdb=HEAD gformat=stabs+ glevel=2
gdb.c++/inherit.exp
gdb.c++/local.exp
I will investigate these.

. Old Bugs Fixed
Daniel J improved ax-gdb.c to handle LOC_COMPUTED and
LOC_COMPUTED_ARG. This fixed:

. Counts
gdb 5.3: 0 test aborts, 329 non-PASS results
gdb HEAD: 0 test aborts, 267 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.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.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 '2003-03-01 00:59:37 UTC'
. gdb.c++/annota2.exp: annotate-quit
Same analysis as 5.3.

XFAIL -> PASS
David C improved the test script so that it accepts more
output as legal.

XFAIL -> PASS
David C improved the test script and added more tests.
. gdb.threads/killed.exp: GDB exits after multi-threaded program exits messily
Same analysis as 5.3.
. gdb.threads/schedlock.exp: *
I'm tired this week, and so are the similes.
This test is still in a state where it's better to analyze the
absolute results than to compare results from date to date.
. gdb.trace/packetlen.exp: setup collect actions
Daniel J fixed a bug in gdb.

'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.
