* glsl ubo/ssbo: Add lower_buffer_access classJordan Justen2015-12-094-183/+286
| | | | | | | | | | | | | | | | | This class has code that will be shared by lower_ubo_reference and lower_shared_reference. (lower_shared_reference will be used to support compute shader shared variables.) v2: * Add lower_buffer_access.h to makefile (Emil) * Remove static is_dereferenced_thing_row_major from lower_buffer_access.cpp. This will become a lower_buffer_access method in the next commit. * Pass mem_ctx as parameter rather than using a member variable (Iago) Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]> Reviewed-by: Kristian Høgsberg <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | Improves register pressure, since otherwise we end up emitting loads for all the elements in the RHS and them emitting stores for all elements in the LHS. v2: - Mark progress properly. This also fixes some instances where the added nodes with individual element copies where not being lowered, which is expected behavior as explained in the documentation for visit_list_elements. - Only need to do this if the RHS is a buffer-backed variable. - We can also have arrays inside structs. A later patch will make it so we also split struct copies and end up with multiple ir_dereference_record assignments, so make sure that if any of these is an array copy, we also split it.

| | | | | | | | | | | | | | | | | | | | | The current implementation looks for array dereferences on gl_FragData and immediately proceeds to lower them, however this is not enough because we can have array access on vector variables too, like in this code: out vec4 color; void main() { int i; for (i = 0; i < 4; i++) color[i] = 1.0; } Fix it by making sure that the actual variable being dereferenced is an array.

| | | | | | | | | | | | | | | | | | | This change allows used defined inputs/outputs with explicit locations to be removed if they are detected to not be used between shaders at link time. To enable this we change the is_unmatched_generic_inout field to be flagged when we have a user defined varying. Previously explicit_location was assumed to be set only in builtins however SSO allows the user to set an explicit location. We then add a function to match explicit locations between shaders.

* nir/validate: Validated dests after sourcesJason Ekstrand2015-11-231-9/+9
| | | | | | | | | | | | | Previously, if someone accidentally made an instruction that refers to its own SSA destination, the validator wouldn't catch it. The reason for this is that it validated the destination too early and, by the time it got to the source, the destination SSA value was already added to the set of seen SSA values so it would assume that it came from some previous instruction. By moving destination validation to be after source validation, the SSA value is not in the list of seen values and the validator will catch self-referential instructions.

| | | | | | | | | | | | | | | | | | | | | | | ARB_explicit_uniform_location allows the index for subroutine functions to be explicitly set in the shader. This patch reduces the restriction on the index qualifier in validate_layout_qualifiers() to allow it to be applied to subroutines and adds the new subroutine qualifier validation to ast_function::hir(). ast_fully_specified_type::has_qualifiers() is updated to allow the index qualifier on subroutine functions when explicit uniform locations is available. A new check is added to ast_type_qualifier::merge_qualifier() to stop multiple function qualifiers from being defied, before this patch this would cause a segfault. Finally a new variable is added to ir_function_signature to store the index. This value is validated and the non explicit values assigned in link_assign_subroutine_types().

We also update the process_qualifier_constant() helper to be similar to the one in the ast_layout_expression class, but in this case it will be used to process the ast_expression qualifiers.

| | | | | | | | | | | | | | | | | | | | | | | In this patch we introduce a new ast type for holding the new compile-time constant expressions. The main reason for this is that we can no longer do merging of layout qualifiers before they have been converted into GLSL IR so we need to store them to be proccessed later. The new type has two helper functions: - process_qualifier_constant() Used to merge and then evaluate qualifier expressions - merge_qualifier() Simply appends a qualifier to a list to be merged later by process_qualifier_constant() In order to avoid cascading error messages the process_qualifier_constant() helpers return a bool Reviewed-by: Emil Velikov <[email protected]>

* glsl: encapsulate binding validation and settingTimothy Arceri2015-11-211-32/+28
| | | | | | | | | | | | | | | | | | This change moves the binding layout handing code into an apply function to be consistent with other helper functions in the ast code, and to encapsulate the code so that when we introduce compile time constants the code will be much cleaner. One small downside is for unnamed interface blocks we will now be revalidating the binding for each member its applied to. However this seems a small sacrifice in order to have code which is readable. We also remove the incorrect comment in the named interface code about propagating bindings to members which seems to have been copied from the unnamed interface code.
