This necessitated hand-writing qfv_swapchain_t's descriptors as I don't
feel like getting that complicated with vkgen at this stage and it's not
really appropriate anyway? qfv_swapchain_t is meant to be read-only and
not parsed from a plist.
The tool is horrible as a built tool due to it not being silent when all
is good (it outputs the input file name) and sends its error messages to
stdout instead of stderr. Then filtering causes the error code to be
lost. This uses a solution found on stack-exchange.
The prototypes for handle parsers needed to be changes because it turned
out "single" was inappropriate for handles as "single" allocates memory
for the parsed object, but handles must be written directly.
The way I wound up using the field meant that exprctx should not "own"
the hashlinks chain, but rather just point to it. This fixes the nasty
access errors I had.
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.
Block expressions hide ex_error, but get_type() always returns null when
it finds one (which it does by recursing into block expression), so just
check the type itself.
I want to be able to use name references, but that requires string
items, so anything that would normally be dictionary or array (or
binary, even) would also need to accept string. This seemed to be the
cleanest solution. Any custom parser would then need to check the type
and act appropriately, but any inappropriate types have already been
pre-filtered by the standard parsers.
Care needs to be taken to ensure the right function is used with the
right arguments, but with these, the need to use qconj(d|f) for a
one-off inverse rotation is removed.
I forgot to right-shift the value so offsets were becoming 0 or 8
instead of 0-15. This fixes the management of small objects. It turns
out that after this fix, qfvis's problems were caused by fragmentation
in the windings. Need to revisit line allocation and use POT-specialized
pools.
I think the sub-line allocator falling over is the final source of
qfvis's leaks. It certainly causes a mess of the sub-lines. But having
some tests to get working sure beats scratching my head over qfvis :)
They're binned by powers of two (with in between sizes going to the
smaller bin should I make cache-line allocations NPOT (which I think
might be worthwhile). However, there seems to still be a bug somewhere
causing a nasty leak as now my hacked qfvis consumes 40G in less than a
minute.
The idea is to not search through blocks for an available allocation.
While the goal was to speed up allocation of cache lines of varying
cluster sizes, it's not enough due to fragmentation.
