As Matt says, the asm was an attempt to tie down the semantics for negative
operands to match the standard.  I seem to remember seeing cases where if
things were constants gcc would sometimes do the computation in a different
way.  Something about a % b where a was negative non-constant and b was a
constant power of 2 which gcc would compile into a bit-wise and, which is
legal for C but not for ML.  Any way, something like that.
