For my own education, would you please help me understand why the
irix6 -mabi=n32 vs -mabi=64 flag affects this, but other 64 bit
platforms, or sparc -m64, don't see a change?

Sure, I'll give it a try. Thanks for analyzing this one.

State-Changed-Why:
This problem seems to have stopped occuring around Feb 27. I'd feel more comfortable closing it if I was sure it's fixed rather than "hidden". The regression was last seen here:
http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg01250.html
and is gone here:

Essentially, there's no logical answer. We were assuming that
DECL_FIELD_OFFSET meant something it only means sometimes. On platforms
where it meant what we thought it meant, we don't need to warn; elsewhere,
we do.

That's correct behavior; it means that there's no change under that ABI.
So, would you do the magic to make the test not run in that situation?
(I'm happy to do it, but I can't test it, so you have a better chance of
getting it right.)
Thanks!

mips-sgi-irix6.5
>Description:
I'm getting a testsuite failure for g++.dg/abi/empty6.C on mips-sgi-irix6.5 as seen here: http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg00233.html
The error is not new, it appears to have started from the very day the testcase was checked in: http://gcc.gnu.org/ml/gcc-testresults/2002-09/msg00909.html
The logfile says:
FAIL: g++.dg/abi/empty6.C (test for warnings, line 6)
and indeed no -Wabi warning is issued. The failure occurs only when I run the testsuite with -mabi=64, it succeeds without that flag as noted in the test report above.
>How-To-Repeat:
Target mips-sgi-irix6.5 and compile empty6.ii with:
cc1plus -fpreprocessed empty6.ii -quiet -dumpbase empty6.C -mabi=64 -auxbase-strip empty6.C -Wabi -version -fmessage-length=0 -o empty6.C
and note that no -Wabi warning is issued.
