If some stream subobjects are missing, PSO creation will use the
defaults for those elements. For primitive topology, this is
triangle rather than undefined, and for depth stencil, it defaults
to depth disabled until either depth stencil state is encountered
or a DSVFormat is specified.
* These are not required to be supported and some drivers may not handle them,
but on implementations where they are supported we need to support debugging
them.
* This won't catch all cases as it won't be able to detect reads via plain
descriptor, those will still break if this kind of feedback loop is in place.
* With graphics pipeline libraries there can be a different pipeline bound to
the state as the one used to specialise a shader. Since this is a many:1
relationship (per shader object) we can express it with a simple map lookup to
redirect the specialised pipeline.
* This removes a potential narrow race where a capturer is removed or added on
one thread while another thread is iterating the list of capturers for target
control communication.
Changes to Metal protocols to support MacOS SDK 13.1
Removed #if __MAC_OS_X_VERSION_MAX_ALLOWED >= __MAC_12_0 guards now the CI can compile MacOS SDK12.0
* When debugging a pixel or doing quad overdraw we replace the pixel shader and
patch in our own UAV. Previously we were moving other UAVs out of the way that
were visible to the pixel shader, but this fails if a UAV is visible to all
stages and used in a vertex stage.
* Now instead for pixel shader inputs we pick a free space and use it. For quad
overdraw we pick an arbitrary high space to hopefully use the precompiled
shader, and if it's somehow not free we recompile the shader with a free
space.
- Blit fragments and read back results in batch
- Modify per fragment callbacks to reduce number of full replays
- Use defines in the primitiveId shader to toggle between float/int
output
- Deleted WriteClearValues and replace with QueryPostModValues
- Add support for earlier GLSL versions and fix logic for creating primitive id program
- Changed to only run per fragment queries on events with multiple fragments
* This distinction unfortunately does not exist in SPIR-V so we have to carry
around this metadata ourselves. Rather than allowing free specification of
tools based on API, instead pretend that Vulkan and GL SPIR-V are separate
format, and duplicate all SPIR-V tools to handle "both" types. This allows
appropriate tool selection based on the encoding.
