- 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.
* 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.
* This also fixes the problem of capturing 32-bit programs with 64-bit
RenderDoc failing to properly insert environment variables and
error'ing when it tries to do it directly.
* We make shaders into fake resources with IDs, so they can be
identified individually (for replacement, fetching reflection data,
and things like that). This is a little but ugly but worth it for the
simplicity it will provide everywhere else.
* The exact contents depend on the API - on D3D11 this is the bytecode
blob, on Vulkan it's the SPIR-V. On OpenGL it is just a concatenation
of all the source files passed in sequence.
* If there's no replay context we can still use the live connection to
copy and delete captures remotely. Try to use that whenever possible
and warn the user when it's not possible (i.e if the program has been
closed and there's no replay context, we have no way to access the
files anymore).
* If the user tries to open a remote log without a replay context,
prompt them either to swithc to a replay context on that host or to
save the log locally.
* This lets us detect when a remote server has been disconnected and
needs to be restarted, as well as alerting the user if this happens in
the middle of a replay session.
* Pinging other hosts means the context switcher is reasonably up to
date if one of them comes up.
* If the machine idents differ in significant ways that we'd consider
it to be a different platform (currently just OS), and if so mark it
as supported but suggested to be replayed remotely.
