Proposed patch
Richard,
Thank you for the great pointers how to fix this bug. Here is the proposed
patch to fix it, I am now testing it on both x86_64 and ARM.
One thing I am not sure about in this patch is whether I am forgetting a check
before swapping the operands (to optimize `-a + b' into `b - a') -- is any
check needed for {PLUS, MINUS}_EXPR in this case?
Thank you.
