* nir/algebraic: Add lowering for ldexpJason Ekstrand2016-04-131-0/+31
| | | | | | | | | The algorithm used is different from both the naive suggestion from the GLSL spec and the one used in GLSL IR today. Unfortunately, the GLSL IR implementation that we have today doesn't handle denormals (for those that care) or the case where the float source is +-inf. Reviewed-by: Matt Turner <[email protected]>

* nir: Do basic constant reassociation.Kenneth Graunke2016-04-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many shaders contain expression trees of the form: const_1 * (value * const_2) Reorganizing these to (const_1 * const_2) * value will allow constant folding to combine the constants. Sometimes, these constants are 2 and 0.5, so we can remove a multiply altogether. Other times, it can create more immediate constants, which can actually hurt. Finding a good balance here is tricky. While much more could be done, this simple patch seems to have a lot of positive benefit while having a low downside. shader-db results on Broadwell: total instructions in shared programs: 8963768 -> 8961369 (-0.03%) instructions in affected programs: 438318 -> 435919 (-0.55%) helped: 1502 HURT: 245 total cycles in shared programs: 71527354 -> 71421516 (-0.15%) cycles in affected programs: 11541788 -> 11435950 (-0.92%) helped: 3445 HURT: 1224 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eduardo Lima Mitev <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>

* nir/search: Don't match inexact expressions with exact subexpressionsJason Ekstrand2016-04-041-5/+18
| | | | | | | | | | | | | | | | | | | | In the first pass of implementing exact handling, I made a mistake with search-and-replace. In particular, we only reallly handled exact/inexact on the root of the tree. Instead, we need to check every node in the tree for an exact/inexact match. As an example of this, consider the following GLSL code precise float a = b + c; if (a < 0) { do_stuff(); } In that case, only the add will be declared "exact" and an expression that looks for "b + c < 0" will still match and replace it with "b < -c" which may yield different results. The solution is to simply bail if any of the values are exact when matching an inexact expression. Reviewed-by: Ian Romanick <[email protected]>
