+ *
+ * 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.
