I am entirely following the explanation of the failure, but the patch fixes the

testsuite regression and the assembly generated for libgcc/_ssnegSQ.o seems

correct: 



00000000 <__gnu_ssnegsq2>:

   0:    e3500000     cmp    r0, #0

   4:    e2600000     rsb    r0, r0, #0

   8:    a12fff1e     bxge    lr

   c:    e3500000     cmp    r0, #0

  10:    b3e00102     mvnlt    r0, #-2147483648    ; 0x80000000

  14:    e12fff1e     bx    lr





Thanks,
