* nir: Embed the shader_info in the nir_shader againJason Ekstrand2017-05-0911-59/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info from being embedded into being just a pointer. The idea was that sharing the shader_info between NIR and GLSL would be easier if it were a pointer pointing to the same shader_info struct. This, however, has caused a few problems: 1) There are many things which generate NIR without GLSL. This means we have to support both NIR shaders which come from GLSL and ones that don't and need to have an info elsewhere. 2) The solution to (1) raises all sorts of ownership issues which have to be resolved with ralloc_parent checks. 3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been using nir_gather_info to fill out the final shader_info. Thanks to cloning and the above ownership issues, the nir_shader::info may not point back to the gl_shader anymore and so we have to do a copy of the shader_info from NIR back to GLSL anyway. All of these issues go away if we just embed the shader_info in the nir_shader. There's a little downside of having to copy it back after calling nir_gather_info but, as explained above, we have to do that anyway.

Also by attempting to move all constants to the top we increase the chance of constant folding. For example it is a fairly common pattern for shaders to do something similar to this: const float a = 0.5; in vec4 b; in float c; ... b.x = b.x * c; b.y = b.y * c; ... b.x = b.x * a + a; b.y = b.y * a + a; So by simply detecting that constant a is part of the multiplication in ffma and switching it with previous fmul that updates b we end up with: ... c = a * c; ... b.x = b.x * c + a; b.y = b.y * c + a; Shader-db results BDW: total instructions in shared programs: 13011050 -> 12967888 (-0.33%) instructions in affected programs: 4118366 -> 4075204 (-1.05%) helped: 17739 HURT: 1343 total cycles in shared programs: 246717952 -> 246410716 (-0.12%) cycles in affected programs: 166870802 -> 166563566 (-0.18%) helped: 18493 HURT: 7965 total spills in shared programs: 14937 -> 14560 (-2.52%) spills in affected programs: 9331 -> 8954 (-4.04%) helped: 284 HURT: 33 total fills in shared programs: 20211 -> 19671 (-2.67%) fills in affected programs: 12586 -> 12046 (-4.29%) helped: 286 HURT: 33 LOST: 39 GAINED: 33 Some of the hurt will go away when we shuffle things back down to the bottom in the following patch.

* nir/constant_expressions: Don't switch on bit size when not neededJason Ekstrand2017-03-301-14/+23
| | | | | | | | | | | | For opcodes such as the nir_op_pack_64_2x32 for which all sources and destinations have explicit sizes, the bit_size parameter to the evaluate function is pointless and *should* do nothing. Previously, we were always switching on the bit_size and asserting if it isn't one of the sizes in the list. This generates way more code than needed and is a bit cruel because it doesn't let us have a bit_size of zero on an ALU op which shouldn't need a bit_size.

| | | | | | | | | | | | | | | | | | | | | | | | The NIR story on conversion opcodes is a mess. We've had way too many of them, naming is inconsistent, and which ones have explicit sizes was sort-of random. This commit re-organizes things and makes them all consistent: - All non-bool conversion opcodes now have the explicit size in the destination and are named <src_type>2<dst_type><size>. - Integer <-> integer conversion opcodes now only come in i2i and u2u forms (i2u and u2i have been removed) since the only difference between the different integer conversions is whether or not they sign-extend when up-converting. - Boolean conversion opcodes all have the explicit size on the bool and are named <src_type>2<dst_type>. Making things consistent also allows nir_type_conversion_op to be moved to nir_opcodes.c and auto-generated using mako. This will make adding int8, int16, and float16 versions much easier when the time comes. Reviewed-by: Eric Anholt <[email protected]>
