Regressions on x86

Regressions on x86

[Markus Deuling]

Hi,

I have regressions on x86 testsuite.

Starting program:
/home/deuling/gdb/dev/build/gdb/testsuite/gdb.arch/i386-gnu-cfi ^M
Using host libthread_db library "/lib/tls/libthread_db.so.1".^M
Error while reading shared library symbols:^M
I'm sorry, Dave, I can't do that.  Symbol format `elf32-i386' unknown.^M
Error while reading shared library symbols:^M
I'm sorry, Dave, I can't do that.  Symbol format `elf32-i386' unknown.^M
Error while reading shared library symbols:^M I'm sorry, Dave, I can't do
that.  Symbol format `elf32-i386' unknown.^M
^M
Program received signal SIGABRT, Aborted.^M 0x006b77a2 in ?? () from
/lib/ld-linux.so.2^M (gdb) UNRESOLVED: gdb.arch/i386-gnu-cfi.exp: continue
to abort()

Is anyone else seeing this?

Was elfread.o linked in?  If not, what does config.log say about the
-lbfd test?

bfd/elf.o was compiled. elfread.o not.

That is ATTRIBUTE_PACKED, which is always defined by ansidecl.h, which
is always included by bfd.h.  "-I/../bfd" is not a good sign.  It
looks like I messed up.  Please try this patch?
