a5c5fb6118 SPV: Emit extension for using StorageClassStorageBuffer. 2017-05-05 05:09:58 -06:00
steve-lunarg
f1709e7146 HLSL: implement [unroll] and [loop] attributes 
This adds infrastructure suitable for any front end to create SPIR-V loop
control flags.  The only current front end doing so is HLSL.

[unroll] turns into spv::LoopControlUnrollMask
[loop] turns into spv::LoopControlDontUnrollMask
no specification means spv::LoopControlMaskNone

670271890d SPV: Support test #pragma for generating the StorageBuffer storage class. 
Longer term, this storage class should be generated based on the mode
of compilation.

4f1403ed1b SPV: Fix #807: use --hlsl-offsets to allow hlsl-style offsets in a buffer. 
Corresponds to the EShMsgHlslOffsets flag in messages.
Works for both GLSL and HLSL.

e741249b72 HLSL: pass tessellation execution modes through to SPIR-V 
The SPIR-V generator had assumed tessellation modes such as
primitive type and vertex order would only appear in tess eval
(domain) shaders.  SPIR-V allows either, and HLSL allows and
possibly requires them to be in the hull shader.

This change:

1. Passes them through for either tessellation stage, and,

2. Does not set up defaults in the domain stage for HLSl compilation,
to avoid conflicting definitions.

dd8287a109 WIP: HLSL: add structuredbuffer pass by reference in fn params 
This PR adds the ability to pass structuredbuffer types by reference
as function parameters.

It also changes the representation of structuredbuffers from anonymous
blocks with named members, to named blocks with pseudonymous members.
That should not be an externally visible change.

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.
