* nir: prevent use-after-free condition in should_lower_phi()Eduardo Lima Mitev2015-06-021-0/+5
| | | | | | | | | | | | | | | | | | lower_phis_to_scalar() pass recurses the instruction dependence graph to determine if all the sources of a given instruction are scalarizable. To prevent cycles, it temporary marks the phi instruction before recursing in, then updates the entry with the resulting value. However, it does not consider that the entry value may have changed after a recursion pass, hence causing a use-after-free situation and a crash. This patch fixes this by reloading the entry corresponding to the 'phi' after recursing and before updating its value. The crash can be reproduced ~20% of times with the dEQP test: dEQP-GLES3.functional.shaders.loops.while_constant_iterations.nested_sequence_fragment Reviewed-by: Jason Ekstrand <[email protected]>

* nir: Remove sRGB colorspace conversion round-trip.Matt Turner2015-05-221-0/+2
| | | | | | | | | | | | | | | | | | Some shaders in Civilization V and Beyond Earth do pow(pow(x, 2.2), 0.454545) which is converting to and from sRGB colorspace. A more general rule that replaces pow(pow(a, b), c) with pow(a, b * c) actually regresses two shaders in Sun Temple in which the result of the inner pow is used twice, once by another pow and once by another instruction. Also, since 2.2 * 0.454545 isn't exactly one, the more general pattern would have still left us with a pow, and I'm 2.2 * 0.454545 percent sure that's not what they want. instructions in affected programs: 934 -> 886 (-5.14%) helped: 16
* glsl: remove element_type() helperTimothy Arceri2015-05-2211-36/+23
| | | | | | | | | | | | | | We now have is_array() and without_array() that make the code much clearer and remove the need for this. For all remaining calls to this we already knew that the type was an array so returning a null wasn't adding any value. v2: use without_array() in _mesa_ast_array_index_to_hir() and don't use without_array() in lower_clip_distance_visitor() as we want to make sure the array is 2D.

* nir: Get rid of the array elements parameter on load/store intrinsicsJason Ekstrand2015-05-202-12/+9
| | | | | | | | | | | | | Previously, we used intrinsic->const_index[1] to represent "the number of array elements to load" for load/store intrinsics. However, this set to 1 by every pass that ever creates a load/store intrinsic. Also, while it might make some sense for registers, it makes no sense whatsoever in SSA. On top of that, the i965 backend was the only backend to ever support it; freedreno and vc4 just assert that it's always 1. Let's just delete it.

* nir/nir: Use a linked list instead of a hash set for use/def setsJason Ekstrand2015-05-0814-306/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit switches us from the current setup of using hash sets for use/def sets to using linked lists. Doing so should save us quite a bit of memory because we aren't carrying around 3 hash sets per register and 2 per SSA value. It should also save us CPU time because adding/removing things from use/def sets is 4 pointer manipulations instead of a hash lookup. Running shader-db 50 times with USE_NIR=0, NIR, and NIR + use/def lists: GLSL IR Only: 586.4 +/- 1.653833 NIR with hash sets: 675.4 +/- 2.502108 NIR + use/def lists: 641.2 +/- 1.557043 I also ran a memory usage experiment with Ken's patch to delete GLSL IR and keep NIR. This patch cuts an aditional 42.9 MiB of ralloc'd memory over and above what we gained by deleting the GLSL IR on the same dota trace. On the code complexity side of things, some things are now much easier and others are a bit harder. One of the operations we perform constantly in optimization passes is to replace one source with another. Due to the fact that an instruction can use the same SSA value multiple times, we had to iterate through the sources of the instruction and determine if the use we were replacing was the only one before removing it from the set of uses. With this patch, uses are per-source not per-instruction so we can just remove it safely. On the other hand, trying to iterate over all of the instructions that use a given value is more difficult. Fortunately, the two places we do that are the ffma peephole where it doesn't matter and GCM where we already gracefully handle duplicates visits to an instruction. Another aspect here is that using linked lists in this way can be tricky to get right. With sets, things were quite forgiving and the worst that happened if you didn't properly remove a use was that it would get caught in the validator. With linked lists, it can lead to linked list corruption which can be harder to track. However, we do just as much validation of the linked lists as we did of the sets so the validator should still catch these problems. While working on this series, the vast majority of the bugs I had to fix were caught by assertions. I don't think the lists are going to be that much worse than the sets.

* glsl: don't lower fragdata array if the output data types don't matchSamuel Iglesias Gonsalvez2015-05-051-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7e414b58640aee6e243d337e72cea290c354f632 broke the gl_FragData array into separate gl_FragData[i] variables, so drivers can eliminate useless writes to gl_FragData improving their performance. The problem occurs when GLSL IR code is linked in the following case: * The FS output variable base data type does not match gl_FragData one (float vector) * The FS output variable is replaced by gl_out_FragDataX because of commit 7e414b58640aee6 with X from 0 to GL_MAX_DRAW_BUFFERS. Then the FS output variable base data type is lost in the resulting GLSL IR, making that the driver does a wrong assignment to gl_out_FragData components because of unmatching data types. This patch reverts the fragdata array lowering when the output var base data type doesn't match gl_out_FragData, i.e., when output variable base data type is not a float or a float vector.
