[Bug c/15247] New: gas complains "There are only 32 single precision f registers; [0-31]" when compiling glibc-2.3.2/math/dosincos.c

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
    179         fcmped  %fcc2, %f10, %f12
    180         fbg,a,pt %fcc2, .LL17
