* glsl: add new expression types for interpolateAt*Chris Forbes2014-07-121-2/+25

* allow builtin functions to require parameters to be shader inputsChris Forbes2014-07-121-0/+6
| | | | | | | | | | | | | The new interpolateAt* builtins have strange restrictions on the <interpolant> parameter. - It must be a shader input, or an element of a shader input array. - It must not include a swizzle.

* glsl: Make most ir_instruction::as_subclass() functions non-virtual.Matt Turner2014-06-031-109/+52
| | | | | | | | | | | | | | | | | | | | | | | | There are several common ways to check whether an object is a particular subclass: dynamic_cast<>, the as_subclass() pattern, or explicit enum tags. We originally used the virtual as_subclass methods, but later added enum tags as they are much nicer for debugging. Since we have the enum tags, we don't necessarily need to use virtual functions to implement the as_subclass() methods. We can just check the tag and return the pointer or NULL. This saves 18 entries in the vtable, and instead of two pointer dereferences per as_subclass() call most are only three inline instructions. Compile time of sam3/112.frag (the longest compile in a recent shader-db run) is reduced by 5% from 348 to 329 ms (n=500). perf stat of this workload shows: 24.14% reduction in iTLB-loads: 285,543 -> 216,606 42.55% reduction in iTLB-load-misses: 18,785 -> 10,792 Reviewed-by: Juha-Pekka Heikkila <[email protected]>
* glsl: Move ir_type_unset to end of enumeration.Matt Turner2014-06-031-6/+2
| | | | | | | | Now that the constructors set a type, ir_type_unset is not very useful. Move it to the end of the enum (specifically out of position 0) so that enums checks for dereferences and rvalues can save an instruction. Reviewed-by: Juha-Pekka Heikkila <[email protected]>

* glsl: Make is_16bit_constant from i965 an ir_constant method.Kenneth Graunke2014-04-081-0/+15
| | | | | | | | | | | | | | | | | | | | | | The i965 MUL instruction doesn't natively support 32-bit by 32-bit integer multiplication; additional instructions (MACH/MOV) are required. However, we can avoid those if we know one of the operands can be represented in 16 bits or less. The vector backend's is_16bit_constant static helper function checks for this. We want to be able to use it in the scalar backend as well, which means moving the function to a more generally-usable location. Since it isn't i965 specific, I decided to make it an ir_constant method, in case it ends up being useful to other people as well. v2: Rename from is_16bit_integer_constant to is_uint16_constant, as suggested by Ilia Mirkin. Update comments to clarify that it does apply to both int and uint types, as long as the value is non-negative and fits in 16-bits.

* glsl: Refactor is_zero/one/negative_one into an is_value() method.Kenneth Graunke2014-01-071-0/+6
| | | | | | | | | | | | | | | This patch creates a new generic is_value() method, which checks if an ir_constant has a particular value. (For vectors, it must have the single value repeated across all components.) It then rewrites the is_zero/is_one/is_negative_one methods to use this generic helper. All three were basically identical except for the value they checked for. The other difference is that is_negative_one rejects boolean types. The new is_value function maintains this behavior, only allowing boolean types when checking for 0 or 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From section 7.1 (Built-In Language Variables) of the GLSL 4.10 spec: Also, if a built-in interface block is redeclared, no member of the built-in declaration can be redeclared outside the block redeclaration. We have been regarding this text as a clarification to the behaviour established for gl_PerVertex by GLSL 1.50, so we apply it regardless of GLSL version. This patch enforces the rule by adding an enum to ir_variable to track how the variable was declared: implicitly, normally, or in an interface block.

| | | | | | | | | | | | | | | | | | I made this a function (instead of a method of ir_variable) because it made the change set smaller, and I expect that there will be an overload that takes an ir_var_mode enum. Having both functions used the same way seemed better. v2: Add missing case for ir_var_system_value. v3: Change the ir_var_mode_count case to just break. Move the assertion and the return outside the switch-statment.
