Just FYI: first testcase from comment #29 shows the problem with missing i386
addressing mode. First leal is not needed as array can be addressed directly
with flds. A PR 18643 is opened for this bug.

.L2:
        leal 0(,%edx,4), %eax
        flds hphase(%eax)
        fsin
        flds hmag(%eax)
        fchs
        leal 1(%edx), %eax
        cmpl $128, %eax
        movl %eax, %edx
        fmulp   %st, %st(1)
        fmul %st(1), %st
        fstps   (%ecx)
        jne .L2
