[Bug target/23602] New: [4.1 regression] 1081 test failures in libjava, when configured for i486-linux

[debian-gcc at lists dot debian dot org]

configuring HEAD 20050828 for i486-linux (instead of the default i686-linux),
libjava fails with 1081 test failures (instead of two with i686-linux).
apparently all the execution tests fail. I don't see any additional information
from the test log (attached). Compiling the a testcase by hand, and running it,
succeeds.

Environment is current Debian unstable, binutils 2.16.1, glibc-2.3.5.

failures.

That said, I can't get any test to fail when run by hand.  libtool compile
and link line pasted out of the log, as well as the associated LD_LIBRARY_PATH.
What am I missing?

Same thing here. It works, when run from the command line.

I narrowed down the failures a bit.

CVS 20050628 and 20050714 fail with just 17 test cases, this is introduced
between 20050607 and 20050628.

I'm able to reproduce these on the command line (at least with the binaries,
which are kept after running the testsuite).

tracked down the 15 failures to this patch:

2005-06-14  Tom Tromey  <tromey@redhat.com>

       PR libgcj/19877:
       * no-executables.m4: Call real AC_FUNC_MMAP when cache variable
       is set but not 'no'.

2005-06-14  Tom Tromey  <tromey@redhat.com>

       PR libgcj/19877:
       * configure, aclocal.m4, Makefile.in: Rebuilt.

looking at the generated libjava/Makefile, the only interesting difference is

-BACKTRACESPEC = -fno-omit-frame-pointer
+BACKTRACESPEC = -fomit-frame-pointer

but that macro isn't used anywhere.

tracked down the 1000+ test failures to the import of classpath from 20050716
(well not exactly, but between 2005-07-16 00:00 UTC and 02:00 UTC).

Actually, BACKTRACESPEC does make it into libgcj.spec via substitution.

About comment #6 - it doesn't seem to me that this patch could have affected
the setting of BACKTRACESPEC.  The most recent change there was on
01-Jun-05; see libjava/configure.host (via cvs annotate) for details.

About comment #7 - it would be helpful to know how the execution tests
fail.  For instance a gdb backtrace from one of them.

I'm sure that the patches listed in comments #6 and #7 are bogus.

But we've had problems before with unwinding with -mno-accumulate-outgoing-args
(implied by -mtune=i486, implied by i486-linux), plus -fomit-frame-pointer.  I
assume this problem has returned.  But since essentially no one uses this 
combination regularly, we don't know exactly when it failed.

I'm trying to get reduced unwind test cases to fail.  If that works, it'll be
easier than looking at libjava itself.

it would, but running them from the commandline let's the test succeed :-/

Reduced testcase

This reduced testcase triggers the same bug before Richard's patch if compiled
with -fasynchronous-unwind-tables, generating very similar code to what broke
the unwinder in the libjava.lang ArrayTest on i486.  With current trunk, even
after reverting the patch, both the reduced testcase and the Java tests all
pass on an i486-pc-linux-gnu native toolchain.  Even though the generated code
is not significantly different, the EH tables are.  I can't tell immediately
whether the problem is actually fixed, and we could thus remove the patch that
hid the problem before, or if it's just more difficult to trigger now.

Log message:

        * toplev.c (process_options): Warn about unsupported combinations
        of unwind tables and omit-frame-pointer.
        * config/i386/i386.c (override_options): Similarly.  Enable
        accumulate-outgoing-args if not explicitly disabled.
        testsuite/
        * g++.dg/eh/omit-frame-pointer.C: Remove i?86 specific options.
        * g++.dg/eh/omit-frame-pointer2.C: Likewise.
        libjava/
        * configure.host (i?86-*): Set -fomit-frame-pointer in libgcj_flags,
        but not BACKTRACESPEC.
        (x86_64-*): Similarly.  Don't set -ffloat-store in 64-bit mode.
