big: completed set of Int division routines & cleanups · b9caa4ac

Robert Griesemer authored May 04, 2010

- renamed Len -> BitLen, simplified implementation
- renamed old Div, Mod, DivMod -> Que, Rem, QuoRem
- implemented Div, Mod, DivMod (Euclidian definition, more
  useful in a mathematical context)
- fixed a bug in Exp (-0 was possible)
- added extra tests to check normalized results everywhere
- uniformly set Int.neg flag at the end of computations
- minor cosmetic cleanups
- ran all tests

runtime: update godefs usage comment for GOARCH=386 GOOS={darwin,freebsd} · 3c32300c

Giles Lean authored May 03, 2010

When trying to regenerate src/pkg/runtime/darwin/386/defs.h
on a 64 bit capable Snow Leopard (OS X 10.6.3) system I
needed to add -f -m32 to godefs, as this OS and hardware
combination defaults to 64 bit compilation.

For safety, make the same change to the 32 bit FreeBSD
instructions in .../freebsd/defs.c.  (Tested OK and no
problems introduced.)

big: use fast shift routines · 58e77990

Robert Griesemer authored May 01, 2010

- fixed a couple of bugs in the process
  (shift right was incorrect for negative numbers)
- added more tests and made some tests more robust
- changed pidigits back to using shifts to multiply
  by 2 instead of add

  This improves pidigit -s -n 10000 by approx. 5%:

big: improved computation of "karatsuba length" for faster multiplies · 407dbb42

Robert Griesemer authored Apr 30, 2010

This results in an improvement of > 35% for the existing Mul benchmark
using the same karatsuba threshold, and an improvement of > 50% with
a slightly higher threshold (32 instead of 30):

big.BenchmarkMul           500	   6731846 ns/op (old alg.)
big.BenchmarkMul	   500	   4351122 ns/op (new alg.)
big.BenchmarkMul           500	   3133782 ns/op (new alg., new theshold)

Also:
- tweaked calibrate.go, use same benchmark as for Mul benchmark
