* glsl: rename min(), max() functions to fix MSVC buildBrian Paul2014-01-061-2/+2
| | | | | | | | Evidently, there's some other definition of "min" and "max" that causes MSVC to choke on these function names. Renaming to min2() and max2() fixes things. Reviewed-by: Kenneth Graunke <[email protected]>

* glsl: Implement [iu]mulExtended() built-ins for ARB_gpu_shader5.Matt Turner2013-10-071-0/+5
| | | | | | | | | | These built-ins have two "out" parameters, which makes implementing them efficiently with our current compiler infrastructure difficult. Instead, implement them in terms of the existing ir_binop_mul IR (to return the low 32-bits) and a new ir_binop_mul64 which returns the high 32-bits. v2: Rename mul64 -> imul_high as suggested by Ken.

* glsl: Add ir_binop_carry and ir_binop_borrow.Matt Turner2013-10-071-0/+10
| | | | | | | | | Calculates the carry out of the addition of two values and the borrow from subtraction respectively. Will be used in uaddCarry() and usubBorrow() built-in implementations. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl: Add conditional-select IR.Matt Turner2013-09-091-0/+6
| | | | | | | | | | | It's a ?: that operates per-component on vectors. Will be used in upcoming lowering pass for ldexp and the implementation of frexp. csel(selector, a, b): per-component result = selector ? a : b Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl: Add IR builder shortcuts for a bunch of random opcodes.Kenneth Graunke2013-09-091-0/+80
| | | | | | | | | | | | | | | Adding new convenience emitters makes it easier to generate IR involving these opcodes. bitfield_insert is particularly useful, since there is no expr() for quadops. v2: Add fma() and rename lrp() operands to x/y/a to match the GLSL specification (suggested by Matt Turner). Fix whitespace issues. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* glsl: Add a new ir_builder::dotlike() function.Kenneth Graunke2013-09-091-0/+11
| | | | | | | | | | | | dotlike() uses ir_binop_mul for scalars, and ir_binop_dot for vectors. When generating built-in functions, we often want to use regular multiply for scalar signatures, and dot() for vector signatures. ir_binop_dot only works on vectors, so we have to switch opcodes, even if the code is otherwise identical. dotlike() makes this easy.

* glsl: Add IR builder support for generating return statements.Kenneth Graunke2013-09-091-0/+7
| | | | | | | | | We use "ret" as the function name since "return" is a C++ keyword, and "ir_return" is already a class name. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* glsl: Add IR builder support for conditional assignments.Kenneth Graunke2013-09-091-2/+15
| | | | | | | | | | | | | This adds two new signatures: assign(lhs, rhs, condition, writemask); assign(lhs, rhs, condition); All the other existing APIs still exist.

* glsl: Let ir_builder expressions take un-dereferenced variables.Eric Anholt2012-04-131-10/+9
| | | | | | | | | | | Having to explicitly dereference is irritating and bloats the code, when the compiler can detect and do the right thing. v2: Use a little shim class to produce the automatic dereference generation at compile time as opposed to runtime, while also allowing compile-time type checking.

* glsl: Create an ir_builder helper for hand-generating IR.Eric Anholt2012-04-131-0/+69
The C++ constructors with placement new, while functional, are extremely verbose, leading to generation of simple GLSL IR expressions like (a * b + c * d) expanding to many lines of code and using lots of temporary variables. By creating a new ir_builder.h that puts simple generators in our namespace and taking advantage of ralloc_parent(), we can generate much more compact code, at a minor runtime cost. v2: Replace ir_instruction usage with just ir_rvalue. v3: Drop remaining missed as_rvalue() in v2.
