- * calculating the upper half of the product placing the result
- * into a general purpose register. Now *if* the compiler supports
- * inline assembler, then it's not impossible to implement the
- * "bignum" routines (and have the compiler optimize 'em)
- * exhibiting "native" performance in C. That's what BN_UMULT_HIGH
