- * 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.
