* glsl: add new expression types for interpolateAt*Chris Forbes2014-07-121-0/+4
| | | | | | | Will be used to implement interpolateAt*() from ARB_gpu_shader5 Signed-off-by: Chris Forbes <[email protected]> Reviewed-by: Ilia Mirkin <[email protected]>
* glsl: Allow dot() on scalars, and throw out dotlike().Matt Turner2014-03-181-1/+0
| | | | | | | | | | In all uses of dotlike() we're writing generic code that operates on 1-4 component vectors. That our IR requires ir_binop_dot expressions' operands to be 2+ component vectors is an implementation detail that's not important when implementing built-in functions with dot(), which is defined for scalar floats in GLSL.

* 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/+1
| | | | | | | | | | 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/+2

* glsl: Add optional parameters to the ir_factory constructor.Kenneth Graunke2013-09-091-3/+3
| | | | | | | | | | | | | | Each ir_factory needs an instruction list and memory context in order to be useful. Rather than creating an object and manually assigning these, we can just use optional parameters in the constructor. This makes it possible to create a ready-to-use factory in one line: ir_factory body(&sig->body, mem_ctx); Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* glsl: Add IR builder shortcuts for a bunch of random opcodes.Kenneth Graunke2013-09-091-0/+14
| | | | | | | | | | | | | | | 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).

* glsl: Expose IR builder support for arbitrary swizzling.Kenneth Graunke2013-09-091-0/+1
| | | | | | | | | | | | | | | | | IR builder already offers a lot of swizzling functions, such as swizzle_xxxx, swizzle_z, or swizzle_for_size. The swizzle_xxxx style is convenient if you statically know which components you want. swizzle_for_size is great if you want to select the first few components. However, if you want to select components based on, say, a loop counter, none of those are sufficient. IR builder actually already had support for arbitrary swizzling, but didn't expose it. This patch exposes that API. 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/+1
| | | | | | | | | | | | 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/+2

* glsl: Create an ir_builder helper for hand-generating IR.Eric Anholt2012-04-131-0/+35
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.
