Dependencies on vkparse.hinc were spreading through the code which I
didn't want as that removes a lot of the automation from the automake
files. This keeps all parser code internal to vkparse.c's scope, and any
accesses required for enum and struct (not yet) definitions can be
fetched by name.
Array and single type overrides now allow the parsing of the items
themselves to be customized. This makes it easy to handle arrays and
pointers to single items while also using custom specifications, rather
than relying entirely on the custom override.
QC's int type is named "integer" (didn't feel like changing that right
now), so special case it to be "int".
Output the parse func name (instead of "fix me").
Output a parse func for enums (needed for arrays of enums
(VkDynamicState)).
I had missed the array declaration and thus initialized the pointer to
the offset array incorrectly. Didn't show up until I tried using
multiple offsets.
Shaders can be built as spv files and installed into
$libdir/quakeforge/shaders or as spvc files and compiled into the
engine. Loading supports $builtin/name to access builtin shaders,
$shader/path to access external standard shaders and quake filesystem
access for all other paths.
I had forgotten that msaa samples was governed by the driver (as a max)
and the renderpass setup code simply took the max. Thus why 1 vs 8
caused the display to render incorrectly.
It turned out the msaa setting defaulting to 1 instead of 8 was the
problem no idea why at this stage (need to read up on just how that
setting works). Once I understand just how it works, I'll rework the
msaa handling.
This gets renderpass parsing almost working (not hooked up, though). The
missing bits are support for expressions for flags (namely support for
the | operator) and references (eg $swapchain.format). However, this
shows that the basic concept for the parser is working.
Nothing is actually done yet other than parsing the built-in property
list to property list items (the actual parser is just a skeleton), but
everything compiles
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.
The tables are generated from the enums pulled out of the vulkan headers
using a ruamoko program (thanks to its reflection capabilities). They
will be used for parsing property lists used to create render passes and
pipelines.
