With a patch from Jan Hubicka:
http://gcc.gnu.org/ml/gcc-patches/2004-09/msg01178.html

'gcc -O2 -ffast-math -S -march=pentium4 -fomit-frame-pointer' now produces:

test1:
        fldl    4(%esp)
        fldl    16(%esp)
        fldl    28(%esp)
        fsin
        fld     %st(1)
        fptan
        fstp    %st(0)
        fxch    %st(3)
        fsqrt
        fmulp   %st, %st(3)
        faddp   %st, %st(2)
        fabs
        fimull  12(%esp)
        faddp   %st, %st(1)
        fiaddl  24(%esp)
