* glsl: add _mesa_glsl_parse_state object to is_lvalue()Samuel Pitoiset2017-05-061-1/+1
| | | | | | | | | | | | | | | Yes, this is a bit hacky but we don't really have the choice. Plain GLSL doesn't accept bindless samplers/images as l-values while it's allowed when ARB_bindless_texture is enabled. The default NULL parameter is because we can't access the _mesa_glsl_parse_state object in few places in the compiler. One is_lvalue(NULL) call is for IR validation but other checks happen elsewhere, should be safe.

* glsl: disable varying packing for varying used by interpolateAt*Timothy Arceri2017-04-241-0/+2
| | | | | | | | | | | | | | | | | Currently the NIR backends depend on GLSL IR copy propagation to fix up the interpolateAt* function params after varying packing changes the shader input to a global. It's possible copy propagation might not always do what we need it too, and we also shouldn't depend on optimisations to do this type of thing for us. I'm not sure if the same is true for TGSI, but the following commit should re-enable packing for most cases in a safer way, so we just disable it everywhere.

* glsl: Immediately inline built-ins rather than generating calls.Kenneth Graunke2016-09-231-24/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the past, we imported the prototypes of built-in functions, generated calls to those, and waited until link time to resolve the calls and import the actual code for the built-in functions. This severely limited our compile-time optimization opportunities: even trivial functions like dot() were represented as function calls. We also had no way of reasoning about those calls; they could have been 1,000 line functions with side-effects for all we knew. Practically all built-in functions are trivial translations to ir_expression opcodes, so it makes sense to just generate those inline. Since we eventually inline all functions anyway, we may as well just do it for all built-in functions. There's only one snag: built-in functions that refer to built-in global variables need those remapped to the variables in the shader being compiled, rather than the ones in the built-in shader. Currently, ftransform() is the only function matching those criteria, so it seemed easier to just make it a special case. On Skylake: total instructions in shared programs: 12023491 -> 12024010 (0.00%) instructions in affected programs: 77595 -> 78114 (0.67%) helped: 97 HURT: 309 total cycles in shared programs: 137239044 -> 137295498 (0.04%) cycles in affected programs: 16714026 -> 16770480 (0.34%) helped: 4663 HURT: 4923 while these statistics are in the wrong direction, the number of hurt programs is small (309 / 41282 = 0.75%), and I don't think anything can be done about it.

* glsl: Check TCS barrier restrictions at ast_to_hir time, not link time.Kenneth Graunke2016-09-231-0/+19
| | | | | | | | | | | | | | | | | | | | | | | We want to check prior to optimization - otherwise we might fail to detect cases where barrier() is in control flow which is always taken (and therefore gets optimized away). We don't currently loop unroll if there are function calls inside; otherwise we might have a problem detecting barrier() in loops that get unrolled as well. Tapani's switch handling code adds a loop around switch statements, so even with the mess of if ladders, we'll properly reject it. Enforcing these rules at compile time makes more sense more sense than link time. Doing it at ast-to-hir time (rather than as an IR pass) allows us to emit an error message with proper line numbers. (Otherwise, I would have preferred the IR pass...) Fixes spec/arb_tessellation_shader/compiler/barrier-switch-always.tesc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an argument for a structure constructor or initializer doesn't match the expected type, only Section 4.1.10 “Implicit Conversions” are allowed to try to match that expected type. From page 32 (page 38 of the PDF) of the GLSL 1.20 spec: " The arguments to the constructor will be used to set the structure's fields, in order, using one argument per field. Each argument must be the same type as the field it sets, or be a type that can be converted to the field's type according to Section 4.1.10 “Implicit Conversions.”" From page 35 (page 41 of the PDF) of the GLSL 4.20 spec: " In all cases, the innermost initializer (i.e., not a list of initializers enclosed in curly braces) applied to an object must have the same type as the object being initialized or be a type that can be converted to the object's type according to section 4.1.10 "Implicit Conversions". In the latter case, an implicit conversion will be done on the initializer before the assignment is done." v2: Remove also the now redundant constant conversion, the constant_record_constructor helper and the replacement code (Timothy).
