* mesa/glsl: build list of program resources during linkingTapani Pälli2015-04-161-0/+192
| | | | | | | | | | | | | | | | Patch adds ProgramResourceList to gl_shader_program structure. List contains references to active program resources and is constructed during linking phase. This list will be used by follow-up patches to implement hooks for GL_ARB_program_interface_query. It can be also used to implement any of the older shader program query APIs. v2: code cleanups + note for SSBO and subroutines (Ilia Mirkin) v3: code cleanups + assert(MESA_SHADER_STAGES < 8) (Martin Peres) Signed-off-by: Tapani Pälli <[email protected]> Reviewed-by: Martin Peres <[email protected]>
* linker: fix varying linking if SSO program has only gs and fsTapani Pälli2015-04-161-12/+17
| | | | | | | | | | | | | | | | Previously linker did not take in to account case where one would have only gs and fs (with SSO), patch adds the case by refactoring code around assign_varying_locations. This makes sure locations for gs get populated correctly. This was found with some of the SSO subtests of Martin's upcoming GetProgramInterfaceiv Piglit test which passes with the patch, no Piglit regressions. v2: code cleanups (Martin Peres) Signed-off-by: Tapani Pälli <[email protected]> Reviewed-by: Martin Peres <[email protected]>

| | | | | | | | | | | | | | | | | When a vec has more elements than row components in a matrix, the code could end up failing an assert inside assign_to_matrix_column(). This patch makes sure that when there is still room in the matrix for more elements (but in other columns of the matrix), the data is actually assigned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This pass performs a mark and sweep pass over a nir_shader's associated memory - anything still connected to the program will be kept, and any dead memory we dropped on the floor will be freed. The expectation is that this will be called when finished building and optimizing the shader. However, it's also fine to call it earlier, and many times, to free up memory earlier. v2: (feedback from Jason Ekstrand) - Skip sweeping impl->start_block, as it's already in the CF list. - Don't sweep SSA defs (they're owned by their defining instruction) - Don't steal phi sources (they're owned by nir_phi_instr). - Don't steal tex->src (it's owned by the tex_inst itself) - Don't sweep dereference chains (top-level dereferences are owned by the instruction; sub-dereferences are owned by the parent deref). - Don't sweep sources and destinations (SSA defs are handled as part of the defining instruction, and registers are handled as part of function implementations). - Just steal instructions; don't walk them (no longer required). v3: (feedback from Jason Ekstrand) - Steal indirect sources from nir_src/nir_dest.

* nir: Allocate dereferences out of their parent instruction or deref.Kenneth Graunke2015-04-075-37/+41
| | | | | | | | | | | | | | | | | | | | | | | | | Jason pointed out that variable dereferences in NIR are really part of their parent instruction, and should have the same lifetime. Unlike in GLSL IR, they're not used very often - just for intrinsic variables, call parameters & return, and indirect samplers for texturing. Also, nir_deref_var is the top-level concept, and nir_deref_array/nir_deref_record are child nodes. This patch attempts to allocate nir_deref_vars out of their parent instruction, and any sub-dereferences out of their parent deref. It enforces these restrictions in the validator as well. This means that freeing an instruction should free its associated dereference chain as well. The memory sweeper pass can also happily ignore them. v2: Rename make_deref to evaluate_deref and make it take a nir_instr * instead of void *. This involves adding &instr->instr everywhere.
