| 88 | * considering assembler implementation. However! It should be | ||
| 89 | * pointed out that some CPUs (most notably Alpha, PowerPC and | ||
| 90 | * upcoming IA-64 family:-) provide *separate* instruction | ||
| 91 | * calculating the upper half of the product placing the result | ||
| 92 | * into a general purpose register. Now *if* the compiler supports | ||
| 93 | * inline assembler, then it's not impossible to implement the | ||
