Array whose elements are only accessed directly are replaced by the
according number of temporary registers. By doing so the otherwise
reserved register range becomes subject to further optimizations like
copy propagation and register merging.
Thanks to the resulting reduced register pressure this patch makes
the piglits
spec/glsl-1.50/execution -
variable-indexing/vs-output-array-vec3-index-wr-before-gs
geometry/max-input-components
pass on r600 (barts) where they would fail before with a "GPR limit exceeded"
error (even with the spilling that was recently added).
v2: * rename method dissolve_arrays to split_arrays
* unify the tracking and remapping methods for src and dst registers
* also track access to arrays via reladdr*
v3: * enable this optimization only if the driver requests register merge
v4: * Correct comments
* Also update inst->resource if it is an array element
(thanks: Benedikt Schemmer for testing the patches on radeonsi, which
revealed that I was missing tracking this)

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
