- factored out 128-bit muladd and div into arith.go · 8db86824

Robert Griesemer authored Aug 11, 2009

- wrote corresponding fast versions in fast.arith.s
- implemented in-place operations for some routines
- updated existing code to be compatible with in-place
  routines

These changes allow the pidigits benchmark to run
approx. 30% faster. Enabling the assembly routines
in fast.arith.s will give another approx. 3%.
