The shader creation helpers returned S_FALSE when compilation produced no
bytecode - but S_FALSE is a success code, so the FAILED() checks in the
D3D11VertexShader/D3D11FragmentShader constructors never fired and failed_ was
never set. Return E_FAIL instead, and only hand out the bytecode when the shader
object was actually created.
Failed() had no callers at all, so a failed shader was handed to the draw as
usual: VSSetShader(nullptr), CreateInputLayout on empty bytecode, and the
ignored HRESULT from SetupDecFmtForDraw meant IASetInputLayout(nullptr). The
draw then did nothing, with no log line to explain it. Skip the draw and warn
instead, like the GL backend does.
Nothing has generated or used a geometry shader since the GS paths were removed
- GeometryShaderGenerator is gone, and ShaderWriter's BeginGSMain/EndGSMain had
no callers at all. Removes ShaderStage::Geometry and everything hanging off it:
the GS preambles and GSMain helpers in ShaderWriter, the stage mappings in all
three thin3d backends, the D3D11 geometry shader plumbing (curGS_, the pipeline
and module members, gs_4_0 compilation), CreateGeometryShaderD3D11, the unused
PipelineFlags::USES_GEOMETRY_SHADER and PipelineManagerVulkan's
UsesGeometryShader().
Also stop enabling the Vulkan geometryShader device feature, since we no longer
have any use for it.
Kept on purpose: the device feature is still listed in the feature dumps (like
other capabilities we don't use), and the Vulkan shader cache header keeps its
now-always-zero geometry shader count so the on-disk format stays compatible.
Simply rotate each primitive in the index buffer to simulate a different provoking vertex.
Since at this point we have already generated a plain primitive index
buffer, it's easy to manipulate like this.
An even better solution would be to generate rotated index buffers
directly during decode, although that code is super critical and does
not need more complexity..
We could now also enable this for hardware transform but I'm leaving
that for later.
* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
Eventually, this will make it possible to use post-processing with
Vulkan and D3D11. Probably not DX9, though maybe.
Not adding to Android build, there's some strangeness with STL.
