* (please preserve this comment, as this information is _NOT_
* in the documentation provided by AMD).
*
* As described in the documentation, MAD with three unique temporary
* source registers requires the use of the macro version.
*
* However (and this is not mentioned in the documentation), apparently
* the macro version is _NOT_ a full superset of the normal version.
* In particular, the macro version does not always work when relative
* addressing is used in the source operands.
*
* This limitation caused incorrect rendering in Sauerbraten's OpenGL
* assembly shader path when using medium quality animations
* (i.e. animations with matrix blending instead of quaternion blending).
*
* Unfortunately, I (nha) have been unable to extract a Piglit regression
* test for this issue - for some reason, it is possible to have vertex
* programs whose prefix is *exactly* the same as the prefix of the
* offending program in Sauerbraten up to the offending instruction
* without causing any trouble.
*
* Bottom line: Only use the macro version only when really necessary;
* according to AMD docs, this should improve performance by one clock
* as a nice side bonus.
