Since revision 140892 (r140513 works) the following tests fail in both 32 and
64 bit modes:

Basically Apple's as does not have support for this instruction, I could use
.long if really needed for this test.

There was similar problem on x86 target with sun as and ffreep mnemonic. This
was fixed by a configure check and conditional generation of either "ffreep" or
".word\t0xXXXX".

Please grep for HAVE_AS_IX86_FFREEP.

Isn't this just a user error though?
I mean, for -mavx we also need an assembler that supports AVX instructions,
we don't have a workaround for every AVX instruction.  Even if you build with
-march=native on SSSE3 capable CPU (i.e. core2 or later) GCC assumes your
assembler supports SSSE3.  Similarly for many other recently added
instructions.
lvlx insn is guarded with rs6000_cpu == PROCESSOR_CELL, how that got set?  Are
you configuring gcc with a cell arch eventhough your assembler lacks that
support?  Or is testing done with those flags?

I am just running the tests.

I use:

../gcc-4.4-work/configure --prefix=/opt/gcc/gcc4.4w
--mandir=/opt/gcc/gcc4.4w/share/man --infodir=/opt/gcc/gcc4.4w/share/info
--build=powerpc-apple-darwin9
--enable-languages=c,c++,fortran,objc,obj-c++,java --with-gmp=/sw
--with-libiconv-prefix=/usr --with-system-zlib --x-includes=/usr/X11R6/include
--x-libraries=/usr/X11R6/lib

If there is something about cell, it is not visible here.

> Or is testing done with those flags?

I don't think I have anything special for these tests.

Created an attachment (id=16615)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16615&action=view)
gcc44-pr37812.patch

Ah, I see, it is a testsuite bug then.  altivec_check.h uses the lvlx insns
inside of inline assembly unconditionally.  There is no reason for that
if not -mcpu=cell and when -mcpu=cell is used, the user and/or testcase should
better make sure the assembler supports cell.  Which leads to another bug, we
need a new target-supports tcl function and guard all the -mcpu=cell tests with
it (say powerpc_cell_ok or powerpc_ppu_ok, which would imply powerpc_altivec_ok
and that these insns can be assembled).

With the updated patch I now get only three failures for the powerpc directory

Are these failures related to this PR or should I open a new one?

Unrelated.  For ppc64-double-1.c I think there is another PR open already.
