* glsl: Add a CSE pass.Eric Anholt2013-11-011-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | This only operates on constant/uniform values for now, because otherwise I'd have to deal with killing my available CSE entries when assignments happen, and getting even this working in the tree ir was painful enough. As is, it has the following effect in shader-db: total instructions in shared programs: 1524077 -> 1521964 (-0.14%) instructions in affected programs: 50629 -> 48516 (-4.17%) GAINED: 0 LOST: 0 And, for tropics, that accounts for most of the effect, the FPS improvement is 11.67% +/- 0.72% (n=3). v2: Use read_only field of the variable, manually check the lod_info union members, use get_num_operands(), rename cse_operands_visitor to is_cse_candidate_visitor, move all is-a-candidate logic to that function, and call it before checking for CSE on a given rvalue, more comments, use private keyword.

* glsl: Make mode_string function globally availableIan Romanick2013-10-301-0/+3
| | | | | | | | | | | | | | | | | | 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. In the unlikely event that var->mode is an invalid value other than ir_var_mode_count, the assertion will still fire, and in release builds we won't wind up returning a garbage pointer.

* glsl: Basic support for built-in intrinsics.Francisco Jerez2013-10-291-0/+6
| | | | | | | | | | | | | | | | | Fix the linker to deal with intrinsic functions which are undefined all the way down to the driver back-end, and introduce intrinsic definition helpers in the built-in generator. We still need to figure out what kind of interface we want for drivers to communicate to the GLSL front-end which of the supported intrinsics should use a default GLSL implementation and which should use a hardware-specific override. As there's no default GLSL implementation for atomic ops, this seems like something we can worry about later on.

| | | | | | | | | | | | | | | | | | | We were already setting the array size of unsized arrays that appeared inside unnamed interface blocks, but we weren't updating ir_variable::interface_type to reflect the new array size, causing bogus link errors. This patch causes array_sizing_visitor to keep track of all the unnamed interface types it sees, and the ir_variables corresponding to each one. After the visitor runs, a new function, fixup_unnamed_interface_types(), adjusts each unnamed interface type to correctly correspond with the array sizes in the ir_variables.

* glsl: Write a new built-in function module.Kenneth Graunke2013-09-091-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates a new replacement for the existing built-in function code. The new module lives in builtin_functions.cpp (not builtin_function.cpp) and exists in parallel with the existing system. It isn't used yet. The new built-in function code takes a significantly different approach: Instead of implementing built-ins via printed IR, build time scripts, and run time parsing, we now implement them directly in C++, using ir_builder. This translates to faster load times, and a much less complex build system. It also takes a different approach to built-in availability: each signature now stores a boolean predicate, which makes it easy to construct arbitrary expressions based on _mesa_glsl_parse_state's fields. This is much more flexible than the old system, and also easier to use. Built-ins are also now stored in a single gl_shader object, rather than being spread out across a number of shaders that need to be linked. When searching for a matching prototype, we simply consult the availability predicate. This also simplifies the code. v2: Incorporate Matt Turner's feedback: use the new fma() function rather than expr(). Don't expose textureQueryLOD() in GLSL 4.00 (since it was renamed to textureQueryLod()). Also correct some #undefs. v3: Incorporate Paul Berry's feedback: rename legacy to compatibility; add comments to explain a few things; fix uvec availability; include shaderobj.h instead of repeating the _mesa_new_shader prototype. v4: Fix lack of TEX_PROJECT on textureProjGrad[Offset] (caught by oglc).

| | | | | | | | | | | | | | | | | | | | | | | During compilation, we'll use this to determine built-in availability. The plan is to have a single shader containing every built-in in every version of the language, but filter out the ones that aren't actually available to the shader being compiled. At link time, we don't actually need this filtering capability: we've already imported prototypes for every built-in that the shader actually calls, and they're flagged as is_builtin(). The linker doesn't import any additional prototypes, so it won't pull in any unavailable built-ins. When resolving prototypes to function definitions, the linker ensures the values of is_builtin() match, which means that a shader can't trick the linker into importing the body of an unavailable built-in by defining a suspiciously similar prototype. In other words, during linking, we can just pass in NULL. It will work out fine.

* glsl: Store a predicate for whether a built-in signature is available.Kenneth Graunke2013-09-091-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | For the upcoming built-in function rewrite, we'll need to be able to answer "Is this built-in function signature available?". This is actually a somewhat complex question, since it depends on the language version, GLSL vs. GLSL ES, enabled extensions, and the current shader stage. Storing such a set of constraints in a structure would be painful, so instead we store a function pointer. When creating a signature, we simply point to a predicate that inspects _mesa_glsl_parse_state and answers whether the signature is available in the current shader. Unfortunately, IR reader doesn't actually know when built-in functions are available, so this patch makes it lie and say that they're always present. This allows us to hook up the new functionality; it just won't be useful until real data is populated. In the meantime, the existing profile mechanism ensures built-ins are available in the right places.

| | | | | | | | | | | | | | | | | | | Previously, we had separate constructors for one, two, and four operand expressions. This patch consolidates them into a single constructor which uses NULL default parameters. The unary and binary operator constructors had assertions to verify that the caller supplied the correct number of operands for the expression, but the four-operand version did not. Since get_num_operands for ir_quadop_vector returns the number of vector_elements, we can safely add that without breaking the semantics of ir_quadop_vector. This also paves the way for expressions with three operands. Currently, none can be constructed since get_num_operands() never returns 3.
