* glsl/linker: Allow link_intrastage_shaders when there is no main()Ian Romanick2016-11-101-0/+9
| | | | | | | | This enables a sort of par-linking. The primary use for this feature is resolving built-in functions in the stand-alone compiler. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]>
* linker: Remove unnecessary overload of program_resource_visitor::visit_fieldIan Romanick2016-11-101-13/+1
| | | | | | | | | | | | | It looks like I added this version as a short-hand for users that didn't need the fuller version. I don't think there's any real utility in that. I'm not sure what my thinking was there. Maybe if those users overloaded the recursion function could just call the compact version to avoid passing some parameters? None of the users do that. Either way, having this extra overload is not useful. Delete it. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>

* glsl: simplify link_uniform_blocks()Timothy Arceri2016-06-301-2/+1

* glsl/mesa: split gl_shader in twoTimothy Arceri2016-06-301-5/+5
| | | | | | | | | | | | | | | | | There are two distinctly different uses of this struct. The first is to store GL shader objects. The second is to store information about a shader stage thats been linked. The two uses actually share few fields and there is clearly confusion about their use. For example the linked shaders map one to one with a program so can simply be destroyed along with the program. However previously we were calling reference counting on the linked shaders. We were also creating linked shaders with a name even though it is always 0 and called the driver version of the _mesa_new_shader() function unnecessarily for GL shader objects.

* glsl: use enum glsl_interface_packing in more places. (v2)Dave Airlie2016-06-061-4/+4
| | | | | | | | | | | | | | | Although the glsl_types.h stores this in a bitfield, we should hide that from everyone else. Hide the cast in an accessor method and use the enum everywhere. This makes things a bit nicer in gdb, and improves type safety. v2: fix a few pieces of interface I missed that caused some piglit regressions.

* glsl: fully split apart buffer block arraysTimothy Arceri2016-04-061-2/+5
| | | | | | | | | | | | With this change we create the UBO and SSBO arrays separately from the beginning rather than putting them into a combined array and splitting it apart later. A bug is with UBO and SSBO stage reference querying is also fixed as we now use the block index to lookup the references in the separate arrays not the combined buffer block array.

* glsl: generate named interface block names correctlyTimothy Arceri2016-03-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firstly this updates the named interface lowering pass to store the interface without the arrays removed. Note we need to remove the arrays in the interface/varying matching code to not regress things but in future this should be fixed futher as it would seem we currently successfully match interface blocks with differnt array sizes. Since we now know if the interface was an array we can reduce the IR flags from_named_ifc_block_array and from_named_ifc_block_nonarray to just from_named_ifc_block. Next rather than having a different code path for named interface blocks in program_resource_visitor we just make use of the one used by UBOs this allows us to now handle arrays of arrays correctly. Finally we add a new param to the recursion function named_ifc_member this is because we only want to process a single member at a time. Note that this is also the glsl_struct_field from the original ifc type before lowering rather than the type from the lowered variable. This fixes a bug in Mesa where we would generate the names like WithInstArray[0].g[0][0] when it should be WithInstArray[0].g[0] for the following interface. out WithInstArray { float g[3]; } instArray[2]; Reviewed-by: Dave Airlie <[email protected]>

* compiler/glsl: Fix uniform location counting.Plamena Manolova2016-02-181-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the calculation of current uniforms to link_uniforms, which makes use of UniformRemapTable which stores all the reserved uniform locations. Location assignment for implicit uniforms now tries to use any gaps left in the table after the location assignment for explicit uniforms. This gives us more space to store more uniforms. Patch is based on earlier patch with following changes/additions: 1: Move the counting of explicit locations to check_explicit_uniform_locations and then pass the number to link_assign_uniform_locations. 2: Count the number of empty slots in UniformRemapTable and store them in a list_head. 3: Try to find an empty slot for implicit locations from the list, if that fails resize UniformRemapTable.
