* We can still highlight them as empty the same as we do for insufficiently
sized constant buffers, but we should display the proper resource contents.
* E.g. on D3D12 we can debug DXBC shaders but not DXIL shaders. On vulkan this
will allow us to have the UI work better when encountering shaders with
unsupported capabilities or extensions.
* We change to use VarType instead of CompType for signature parameters which
allows us to represent different types of variables beyond just
unsigned/signed integer and float.
D3D12Pipe now stores an array of root elements, each one corresponding
to a root element or range in the root signature. Migrated usage in the
D3D12 pipeline state viewer and PipeState retrieval of resources.
Restricted number of resource array textures displayed in the texture
viewer to prevent app hangs.
* We instead always have 3rdparty/ in the relevant include search paths and rely
on that. Each library still has its own unique base dir within 3rdparty to
clarify where the include is coming from.
Checks to enable debugging and pixel history are gated by the
APIProperties instead of whether the capture is D3D11. Shader
debugging for D3D12 is gated on a config option, which can be enabled
by adding "d3d12ShaderDebugging": "true" to the ConfigSettings
With SM5.1 and D3D12, constant buffer arrays can be declared which
are treated as an array of resources on the shader side, and a simple
collection of descriptors on the D3D12 side. DXBCDebug::GlobalState
handles the bridge between these by storing each array resource as a
nested ShaderVariable struct. Accessing the data for instructions
traverses the structure similarly. The shader viewer handles nested
resources and displays them in the appropriate tree view. In the
pipeline viewer, descriptors for CB arrays now indicate the array
index and correctly handle buffer offsets for viewing.
* The ShaderDebugTrace now only sets up the initial state of an opaque
ShaderDebugger handle.
* This handle can then be passed to a new function - ContinueDebug - to
iteratively return N more states. The number of states is implementation
defined and may be a fixed number or it may run for a fixed time.
* The states themselves no longer contain a complete snapshot of all variables,
but instead only the changed variables for that iteration. The changes are
stored as before and after value to make it easier to step forwards and
backwards (only the ShaderDebugState is needed to move forward or backwards,
you don't have to search back for the last set value of a variable to 'undo' a
change).
* Mostly moving includes from common headers to cpp where possible, and removing
includes of the whole thing where only enums or rdcstr etc are needed.
* Subresource handling is more consistent - we pass around a struct now that
contains the array slice, mip level, and sample. We remove the concept of
'MSAA textures count samples as extra slices within the real slices' and
internalise that completely. This also means we have a consistent set
everywhere that we need to refer to a subresource.
* Functions that used to be in the ReplayOutput and use a couple of implicit
parameters from the texture viewer configuration are now in the
ReplayController and take them explicitly. This includes GetMinMax,
GetHistogram, and PickPixel.
* Since these functions aren't ReplayOutput relative, if you want to decode the
custom shader texture or the overlay texture you need to pass that ID
directly.
* Previously we had "Frame X" and "Start of Frame" hardcoded in the event
browser, and the end of frame was in many cases assumed to be a present call.
However with the in-application API this is not necessarily true.
* Presents are now serialised separately in all APIs and displayed wherever they
happen in the frame, and if there is no present at the end of the frame an
"End of Capture" marker is inserted. Similarly API-defined captures are not
given a potentially misleading frame number.
* When the same sampler is used in multiple combined image/sampler descriptors
we only list the sampler once to avoid really verbose unnecessary rows. Use
row highlighting to indicate which sampler is used with which image, and add
it to the view details tooltip with the image layout
