- ShaderDebugState now carries a 'flags' that can be updated when the interpreter is run. Currently supported flags are 'sample/load/gather insn' or 'insn generated nan/inf'.
- DXBC interpreter now pushes operation type into results for simple intrinsics. This avoids the situation where temp decls are by default uint-typed, and any arithmetic operation on float or double operands would result in a uint shader variable. Other intrinsics are largely correct because they create temporaries with appropriate typed constructors.
- Provide icons for user interface elements, based on the existing 'run to' icons with modifications by myself.
A canonical UI paradigm is that when you have a dialog with a list of
items as a central element and an "Ok" action, double-clicking the item
results in the dialog confirmation.
This change adds this behavior to the Capture dialog.
* It was using the last bound render target, which could be empty if
state was reset before presentation. Instead we use the copy target
listed in the present drawcall as the actual swap buffer presented to.
* DDS will always save the format entirely literally, and the float
formats do not support alpha processing currently.
* TGA and PNG will either discard the alpha and write entirely opaque,
or they'll include it in the file. Blending to colour or checkerboard
is not supported.
* By renaming the renderdoc and renderdoccmd projects to something else
(say 'selfhost' and 'selfhostcmd') then they can be used to capture
renderdocui and the replaying that's happening.
* Only supported on development builds and might break down, but it's
handy to have as an easy to enable option.
* There's also a couple of handy python functions exposed -
renderdoc.StaticExports.StartSelfHostCapture(string dllname)
renderdoc.StaticExports.EndSelfHostCapture(string dllname)
which can be used to start and stop the capture around e.g. a shader
debug operation or a pixel history operation or something similar.
