* glsl/ir: allow ir_call to handle subroutine callingDave Airlie2015-07-231-1/+20

| | | | | | | | | | | This will be used to identify buffer variables inside shader storage buffer objects, which are very similar to uniforms except for a few differences, most important of which is that they are writable. Since buffer variables are so similar to uniforms, we will almost always want them to go through the same paths as uniforms. Reviewed-by: Jordan Justen <[email protected]>

* glsl: Annotate as_foo functions that the this pointer cannot be NULLIan Romanick2015-03-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use the idiom ir_foo *x = y->as_foo(); if (x == NULL) return; all over the place. GCC generates some quite lovely code for this. One such example: 340a5b: 83 7d 18 04 cmpl $0x4,0x18(%rbp) 340a5f: 0f 85 06 04 00 00 jne 340e6b 340a65: 48 85 ed test %rbp,%rbp 340a68: 0f 84 fd 03 00 00 je 340e6b This case used as_expression() (ir_type_expression is 4). Note that it checks the ir_type, then checks that the pointer isn't NULL. There is some disconnect in GCC around the condition in the as_foo functions. return ir_type == ir_type_##TYPE ? (ir_##TYPE *) this : NULL; \ It believes "this" could be NULL, so it emits check outside the function just for fun. This patch uses assume() to tell GCC that it need not bother with extra NULL checking of the pointer returned by the as_foo functions. text data bss dec hex filename 4836430 158688 26248 5021366 4c9eb6 i965_dri-before.so 4836173 158688 26248 5021109 4c9db5 i965_dri-after.so v2: Replace 'if (this == NULL) unreachable("this cannot be NULL")' with assume(this != NULL).

| | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new search function to look for matching built-in functions by name and use it for built-in function redefinition or overload in GLSL ES 3.00.

| | | | | | | | | | | | | | | | | | Historically, we've implemented the rules for overriding built-in functions by creating multiple ir_functions and relying on the symbol table to hide the one containing built-in functions. That works, but has a few drawbacks, so the next patch will change it. Instead, we'll have a single ir_function for a particular name, which will contain both built-in and user-defined signatures. Passing an extra parameter to matching_signature makes it easy to ignore built-ins when they're supposed to be hidden.

* 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: Reorder ir_type_* enum for easier comparisons.Matt Turner2014-06-031-7/+7
| | | | | | | | Makes checking whether an object is an ir_dereference, an ir_rvalue, or an ir_jump simpler. Since ir_dereference is a subclass or ir_rvalue, list its subtypes first so that they can both generate nice code. Reviewed-by: Juha-Pekka Heikkila <[email protected]>
* glsl: Set ir_instruction::ir_type in the base class constructorIan Romanick2014-06-031-19/+27
| | | | | | | | | | | | This has the added perk that if you forget to set ir_type in the constructor of a new subclass (or a new constructor of an existing subclass) the compiler will tell you... instead of relying on ir_validate or similar run-time detection.

* 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.
