Compile the attached file z.i with -O -fcall-used-g6 -save-temps,
and you should see
z.s:174: Error: Illegal operands: There are only 32 single precision f
registers; [0-31]
Here are lines 172 to 180 of the resulting z.s,
not sure which line it's complaining about (gas
seems to get line numbers wrong):

    172         fcmped  %fcc1, %f32, %f10
    173         fmovd   %f8, %f10
    174         fmovdg  %fcc1, %f32, %f10
    175         fzero   %f8
    176         fcmped  %fcc1, %f12, %f8
    177         fbule,pt %fcc1, .LL11
    178         fsubd   %f32, %f12, %f14

I want to say this is binutils bug from the sparc target header:
   SPARC has 32 integer registers and 32 floating point registers.
   64 bit SPARC has 32 additional fp regs, but the odd numbered ones are not
   accessible.  We still account for them to simplify register computations
   (eg: in CLASS_MAX_NREGS).  There are also 4 fp condition code registers, so
   32+32+32+4 == 100.
   Register 100 is used as the integer condition code register.
   Register 101 is used as the soft frame pointer register.  */

Here's how I configured the bootstrap gcc:

../gcc-3.4.0/configure --target=sparc64-unknown-linux-gnu
--host=i686-host_pc-linux-gnu
--prefix=/opt/crosstool/sparc64-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2

Here's the output of 'gcc -v options' (hmm, I must misunderstand what you wanted):

Jakub's been dealing with these, so I'm cc'ing him on this.

I'd find it surprising that gas gets line numbers wrong.  So it appears to be
complaining about

174         fmovdg  %fcc1, %f32, %f10

which is fully valid as far as I know.  'fmovsg' would be problematic.

Could you manually reduce the assembly file so as to narrow down the problem to
a single line?

What binutils did you use?
I certainly cannot reproduce this with current CVS binutils.
Make sure you have:
2004-04-20  Jakub Jelinek  <jakub@redhat.com>

        * sparc-opc.c (fmoviccx, fmovfccx, fmovccx): Define.
        (fmovicc, fmovfcc, fmovcc): Remove fpsize argument, change opcode to
        suffix.  Use fmov*x macros, create all 3 fpsize variants in one
        macro.  Adjust all users.

opcodes patch.

I am using binutils-2.15.90.0.3.  Your patch seems to have solved my problem.
So I guess my bug report was invalid.  Sorry for the noise,

Subject: Re:  gas complains "There are only 32 single precision
 f registers; [0-31]"  when compiling glibc-2.3.2/math/dosincos.c

I'm not sure that this is the same bug since the bug indicates it's a 
bug in binutils.  I am running a version of binutils that has the fix 
and am still experiencing this problem.  I am running with binutils 2.16.1.
