Add comments marking the beginning and end of coordinate-field operations

2012-03-11T11:04:48+00:00

This makes it much easier for a simple script to extract the
coordinate-field operations for use in other software operating on the
Curve25519 elliptic curve (or other curves with the same coordinate field).

Introduce and use fsquare function in donna-c64

2012-03-11T09:19:15+00:00

(No noticeable performance effect.)

Move crecip next to the other coordinate-field operations

2012-03-11T08:49:38+00:00

Add 'minitest' make target

2012-03-11T07:36:41+00:00

Remove redundant memcpy from fcontract

2012-03-11T07:36:41+00:00

This one clawed back all of the performance loss of the previous commit
(Move memcpy into freduce_coefficients).

Move memcpy into freduce_coefficients

2012-03-11T07:36:41+00:00

This one hurt performance.

Move required freduce_coefficients call into fscalar_product

2012-03-11T07:36:41+00:00

(6 microseconds faster on my box, all due to removing the memset)

Move fscalar_product (without changing it)

2012-03-11T07:36:41+00:00

Use fmul instead of fproduct, freduce_degree, freduce_coefficients

2012-03-11T07:36:41+00:00

And then shorten a bunch of felem_long variables and arguments.

This turns out to be a performance improvement: ~683 -> ~665 microseconds
on my AMD64 development system.
