* nir: Rework conversion opcodesJason Ekstrand2017-03-149-191/+127
| | | | | | | | | | | | | | | | | | | | | | | | 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]>

* nir/validate: Rework ALU bit-size rule validationJason Ekstrand2017-03-141-32/+33
| | | | | | | | | | | The original bit-size validation wasn't capable of properly dealing with instructions with variable bit sizes. An attempt was made to handle it by looking at source and destinations but, because the validation was done in validate_alu_(src|dest), it didn't really have the needed information. The new validation code is much more straightforward and should be more correct. Reviewed-by: Eric Anholt <[email protected]>
* nir/validate: Validate that bit sizes and components always matchJason Ekstrand2017-03-141-38/+63
| | | | | | | | | | | | | We've always required bit sizes to match but the rules for number of components have been a bit loose. You've never been allowed to source from something with less components than you consume, but more has always been fine. This changes the validator to require that they match exactly. The fact that they don't always match has been a source of confusion in NIR for quite some time and it's time we got rid of it.

* nir/copy_prop: Respect the source's number of componentsJason Ekstrand2017-03-141-33/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the near future we are going to require that the num_components in a src dereference match the num_components of the SSA value being dereferenced. To do that, we need copy_prop to not remove our MOVs from a larger SSA value into an instruction that uses fewer channels. Because we suddenly have to know how many components each source has, this makes the pass a bit more complicated. Fortunately, copy propagation is the only pass that cares about the number of components are read by any given source so it's fairly contained. Shader-db results on Sky Lake: total instructions in shared programs: 13318947 -> 13320265 (0.01%) instructions in affected programs: 260633 -> 261951 (0.51%) helped: 324 HURT: 1027 Looking through the hurt programs, about a dozen are hurt by 3 instructions and the rest are all hurt by 2 instructions. From a spot-check of the shaders, the story is always the same: They get a vec4 from somewhere (frequently an input) and use the first two or three components as a texture coordinate. Because of the vector component mismatch, we have a mov or, more likely, a vecN sitting between the texture instruction and the input. This means that the back-end inserts a bunch of MOVs and split_virtual_grfs() goes to town. Because the texture coordinate is also used by some other calculation, register coalesce can't combine them back together and we end up with an extra 2 MOV instructions in our shader.

| | | | | | | | | | | | | | | | | | | | | Because we optimistically skip compiling shaders if we have seen them before we may need to compile them later at link time if they haven't yet been use in a specific combination to create a program. Rather than always recompiling we take advantage of the gl_compile_status enum introduced in the previous patch to only compile when we have previously skipped compilation.

| | | | | | | | | | | | | | | | | | | | | | Builtins are created once and allocated using their own private ralloc context. When reparenting IR that includes builtins, we might be steal bits of builtins. This is problematic because these builtins might now be freed when the shader that includes then last is disposed. This might also lead to inconsistent ralloc trees/lists if shaders are created on multiple threads. Rather than including builtins directly into a shader's IR, we should include clones of them in the ralloc context of the shader that requires them. This fixes double free issues we've been seeing when running shader-db on a big multicore (72 threads) server. v2: Also rename _mesa_glsl_find_builtin_function_by_name() to better reflect how this function is used.

* glsl: fix subroutine mismatch between declarations/definitionsSamuel Pitoiset2017-03-035-8/+18
| | | | | | | | | | | | | | | | | | | | | Previously, when q.subroutine was set to 1, a new subroutine declaration was added to the AST, while 0 meant a subroutine definition has been detected by the parser. Thus, setting the q.subroutine flag in both situations is obviously wrong because a new type identifier is added instead of trying to match the declaration. To fix it up, introduce ast_type_qualifier::is_subroutine_decl() to differentiate declarations and definitions easily.
