* glsl: Make ir_validate actually visit ir_if nodes.Kenneth Graunke2011-08-221-2/+3
| | | | | | | | | | | | There is no ir_hierarchical_visitor::visit(ir_if *) method, since ir_if is not a leaf node. Instead, there are visit_enter and visit_leave methods. Use visit_enter arbitrarily (either would work fine, though visit_enter will catch errors sooner). Found thanks to a warning emitted by Clang.

* glsl: Add validations for ir_call.Paul Berry2011-08-151-0/+36
| | | | | | | | | | | | | | | This patch extends ir_validate.cpp to check the following characteristics of each ir_call: - The number of actual parameters must match the number of formal parameters in the signature. - The type of each actual parameter must match the type of the corresponding formal parameter in the signature. - Each "out" or "inout" actual parameter must be an lvalue.

* glsl: Revert "fix conversions from uint to bool and from..."Kenneth Graunke2011-06-291-3/+3
| | | | | | | | | | Reverts commit f41e1db3273a31285360241c4342f0a403ee0b03 "fix conversions from uint to bool and from float/bool to uint" f2i, b2i, and b2i should not accept uint types. Use i2u and u2i. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* glsl: Add ir_unop_i2u and ir_unop_u2i operations.Bryan Cain2011-06-291-0/+8
| | | | | | | | | | | | | | | | | These are necessary to handle int/uint constructor conversions. For example, the following code currently results in a type mismatch: int x = 7; uint y = uint(x); In particular, uint(x) still has type int. This commit simply adds the new operations; it does not generate them, nor does it add backend support for them.

* glsl: Add several function / call related validationsIan Romanick2011-03-081-0/+27
| | | | | | | | The signature list in a function must contain only ir_function_signature nodes. The target of an ir_call must be an ir_function_signature. These were added while trying to debug Mesa bugzilla #34203.
* glsl: Function signatures cannot have NULL return typeIan Romanick2011-03-081-0/+6
| | | | | The return type can be void, and this is the case where a `_ret_val' variable should not be declared.

* glsl: Add using statements for standard library functions.Vinson Lee2011-02-031-0/+3
| | | | | | | | | | | | | Standard library functions in C++ are in the std namespace. When using C++-style header files for the standard library, some compilers, such as Sun Studio, provide symbols only for the std namespace and not for the global namespace. This patch adds using statements for standard library functions. Another option could have been to prepend standard library function calls with 'std::'. This patch fixes several compilation errors with Sun Studio.

* glsl: Add ir_quadop_vector expressionIan Romanick2010-11-191-0/+45
| | | | | | | | | | The vector operator collects 2, 3, or 4 scalar components into a vector. Doing this has several advantages. First, it will make ud-chain tracking for components of vectors much easier. Second, a later optimization pass could collect scalars into vectors to allow generation of SWZ instructions (or similar as operands to other instructions on R200 and i915). It also enables an easy way to generate IR for SWZ instructions in the ARB_vertex_program assembler.
* glsl: Add ir_unop_sin_reduced and ir_unop_cos_reducedIan Romanick2010-11-191-0/+2
| | | | | | | | | | | | The operate just like ir_unop_sin and ir_unop_cos except that they expect their inputs to be limited to the range [-pi, pi]. Several GPUs require this limited range for their sine and cosine instructions, so having these as operations (along with a to-be-written lowering pass) helps this architectures. These new operations also matche the semantics of the GL_ARB_fragment_program SCS instruction. Having these as operations helps in generating GLSL IR directly from assembly fragment programs.

* glsl: Fix ir validation for bit logic opsChad Versace2010-10-151-5/+9
| | | | | | | | | | | | In ir_validate::visit_leave(), the cases for - ir_binop_bit_and - ir_binop_bit_xor - ir_binop_bit_or were incorrect. It was incorrectly asserted that both operands must be the same type, when in fact one may be scalar and the other a vector. It was also incorrectly asserted that the resultant type was the type of the left operand, which in fact does not hold when the left operand is a scalar and the right operand is a vector.
* glsl: Implement ast-to-hir for binary shifts in GLSL 1.30Chad Versace2010-10-151-0/+13
| | | | | | | | | | Implement by adding the following cases to ast_expression::hir(): - ast_lshift - ast_rshift Also, implement ir validation for the new operators by adding the following cases to ir_validate::visit_leave(): - ir_binop_lshift - ir_binop_rshift

* glsl: Rework assignments with write_masks to have LHS chan count match RHS.Eric Anholt2010-09-221-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that most people new to this IR are surprised when an assignment to (say) 3 components on the LHS takes 4 components on the RHS. It also makes for quite strange IR output: (assign (constant bool (1)) (x) (var_ref color) (swiz x (var_ref v) )) (assign (constant bool (1)) (y) (var_ref color) (swiz yy (var_ref v) )) (assign (constant bool (1)) (z) (var_ref color) (swiz zzz (var_ref v) )) But even worse, even we get it wrong, as shown by this line of our current step(float, vec4): (assign (constant bool (1)) (w) (var_ref t) (expression float b2f (expression bool >= (swiz w (var_ref x))(var_ref edge)))) where we try to assign a float to the writemasked-out x channel and don't supply anything for the actual w channel we're writing. Drivers right now just get lucky since ir_to_mesa spams the float value across all the source channels of a vec4. Instead, the RHS will now have a number of components equal to the number of components actually being written. Hopefully this confuses everyone less, and it also makes codegen for a scalar target simpler. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* glsl: introduce ir_binop_all_equal and ir_binop_any_equal, allow vector cmpsLuca Barbieri2010-09-131-10/+16
| | | | | | | | | | | | | | | | | Currently GLSL IR forbids any vector comparisons, and defines "ir_binop_equal" and "ir_binop_nequal" to compare all elements and give a single bool. This is highly unintuitive and prevents generation of optimal Mesa IR. Hence, first rename "ir_binop_equal" to "ir_binop_all_equal" and "ir_binop_nequal" to "ir_binop_any_nequal". Second, readd "ir_binop_equal" and "ir_binop_nequal" with the same semantics as less, lequal, etc. Third, allow all comparisons to acts on vectors. Signed-off-by: Ian Romanick <[email protected]>
