433e9ff896 SPV: Emit OpSelect when a selection node is simple enough. 
Also, ensures it has a type, no disallowed side effects,
or performance trade offs.

65ee230f1c HLSL: Add tests and refine what decorations are passed through per stage/in/out. 2017-02-06 23:13:16 -07:00
Flavio
aea3c890d3 Added --vn option to generate a C header file containing a variable assigned to the hex representation of the shader. This is a standard feature on Microsoft's HLSL compiler and it allows developers to include pre-compiled shaders directly into the code. This option enables "Hex output", so it is NOT required to specify -x as well. The output file name is preserved, so no ".h" extension is added. If you want the output file to have ".h" extension then you have to specify it on the output file name. The generated header file uses the "#pragma once" pragma to avoid multiple inclusions. 2017-02-06 11:46:35 -08:00

fdf6347f0a HLSL: Add EOpMatrixSwizzle, selectively decomposed to other ops, for issue #670. 
Since EOpMatrixSwizzle is a new op, existing back-ends only work when the
front end first decomposes it to other operations. So far, this is only
being done for simple assignment into matrix swizzles.

- Add support of half float constant: hf, HF.
- Extend built-in floating-point operators: +, -, *, /, ++, --, +=, -=,
  *=, /=, ==, !=, >=, <=, >, <.
- Add support of type conversions: float16_t -> XXX, XXX -> float16_t.
- Add new built-in functions.

4bf7155051 SPV: Flatten structs for copy when they are GLSL type aliases. 
Addresses issue #304 and issue #307 by replacing unmatched type OpStores with
per-member copies. Covers assignment statements and most argument passing, but
does not yet cover r-value-based argument passing.

f2b7f3353b SPV: Tighten up number of struct-types declared based on decoration. 
Takes some pressure off of issue #304.
Structures don't inherit locations and then explicitly decorate
members with them, so removed this reason to have another instance
of a structure type.

f6640761c4 Front-end: Implement 2nd task of issue #400; precision of result and operation. 
From the ES spec + Bugzilla 15931 and GL_KHR_vulkan_glsl:
- Update precision qualifiers for all built-in function prototypes.
- Implement the new algorithm used to distinguish built-in function
  operation precisions from result precisions.
Also add tracking of separate result and operation precisions, and
use that in generating SPIR-V.
(SPIR-V cares about precision of operation, while the front-end
cares about precision of result, for propagation.)

8c8505c604 SPV: For AST interpolateAt* ops consuming a swizzle, invert the order. 
Apply the interpolation first, then apply the swizzle to the result,
the inverse of the order requested by the AST.  This fixes issue #411.
