While the cexpr parser itself doesn't support void functions, they have
their uses when used with the system, and mixing them into the list of
function overloads shouldn't break non-void functions.
The type system rewrite had lost some of the checks for function fields.
This puts the actual code in the one place and covers parameters as well
as globals.
Internally, * is not really a valid operator for vectors since it can
have many meanings. This didn't cause trouble until trying to build
everything in game-source (since there's still a lot of legacy code in
there).
The precedence check changes done in
63795e790b seem to have been incorrect
(game-source/ctf produced many false positives), so putting that check
against '=' back into the code seems like a good idea (no more false
positives). That sounds a bit cargo-cult, but I'm really not sure what I
was thinking when I did the changes (probably just tired).
This applies only to the top-level scope of the function. I'm not sure
if it's right for traditional quakec code, but that can be adjusted
easily enough.
The symtab code itself cares only about global/not global for the size
of the hash table, but other code can use the symtab type for various
checks (eg, parameter shadowing).
At least with a push-parser, by the time the parser has figured out it
has an identifier, the lexer has forgotten the token, thus the annoying
and uninformative "undefined identifier " error messages. Since
identifiers should always have a value (and functions need a function
type), setting up a dummy symbol with just the identifier name
duplicated seems to do the trick. It is a bit wasteful of memory if
there are a lot of such errors between cmem resets, though.
I ran into the need to get at the label of labeled array element and the
best way seemed to be by setting the name field of the plfield_t item
passed to the parser function, and then found that PL_ParseSymtab
already does this. I then decided passing the array index would also be
good, and the offset field made sense.
qfot_basic_t is necessary for getting at the width of basic value types
(int, uint, float, long, ulong, double) in order to distinguish between
scalars and vectors of those types.
I had forgotten this when doing the Ruamoko VM and qfcc changes.
Along with QuakeC's, of course. This fixes type typeredef2 test (a lot
of work for one little syntax error). Unfortunately, it came at the cost
of requiring `>>` in front of state expressions on C-style functions
(QuakeC-style functions are unaffected). Also, there are now two
shift/reduce conflicts with structs and unions (but these same conflicts
are in gcc 3.4).
This has highlighted the need for having the equivalent of the
expression tree for the declaration system as there are now several
hacks to deal with the separation of types and declarators. But that's a
job for another week.
The grammar constructs for declarations come from gcc 3.4's parser (I
think it's the last version of gcc that used bison. Also, 3.4 is still
GPL 2, so no chance of an issue there).
This simplifies type type_specifier rule significantly as now TYPE_SPEC
(was TYPE) includes all types and their basic modifiers (long, short,
signed, unsigned). This should allow me to make the type system closer
to gcc's (as of 3.4 as that seems to be the last version that used a
bison parser) and thus fix typeredef2.
typeredef1 parses properly but fails due to it erroneously complaining
that foo is redeclared as a different kind of object (it's the same
kind).
typeredef2 is the real problem in that it's a syntax error when it
should not be. This has proven to be a show-stopper for development on
my laptop as it has very recent vulkan headers which have such a
duplicate typedef.
Some of the queues start don't get fully initialized, but rather than go
through everything making sure they do, it's just easier to zero the
whole lot at the beginning.
When bubbling a component past an empty range, there's no need for any
actual movement other than adjusting the range itself, and doing so
corrupts the sparse/dense array relationship. Fixes a segfault when
hiding the deathmatch overlay (that resulted from the change to using
canvases).
Canvas_SortComponentPool now takes the raw canvas component id as it is
specialized to the canvas subpools.
Canvas_SetLen resizes the root view and then updates the hierarchy for
every canvas in the system.
Canvas_InitSys sets up the component system with the systems it needs
(canvas, view, text). This is required to ensure view_href is just past
the canvas components as it is needed for retrieving the actual canvas
component (and thus sub-pool range ids) from arbitrary views in the
canvas.
Entities are fetched with the correct offset from the pool entities.
This will make it easy for client code to set up data needed by the
console before the console initializes. It already separates console
cvar setup and initialization, which has generally been a good thing.
The flashing pink around the Q menu cursor was caused by vulkan command
buffer writes and draw queue population being out of phase, which was
fixed by the recent screen update changes (specifically,
42441e87d4).
Rather important for debugging 2d stuff (draw's lines are 2d-only).
Other than translucent console, this gets the vulkan draw api back to
full operation.
This needed either more font ids to be supported, or small lump pics (up
to 32 x 32) to be loaded into the atlas. I went with both. The menus
don't use Draw_TextBox, but quakeworld's netgraph does.
This makes use of slice rendering to achieve the effective scaling, but
the slice data is created only when needed so pics that never use slices
don't waste 16 vertices.
The goal is to get vulkan relying on the "renderpass" abstraction, but
this gets vulkan up and running again, and even fixes the rendering
issues (in the end, getting canvas working wasn't required, but is still
planned).
This is a bit of a hack to allow me to work on vulkan's screen update
"pipeline" without having to mess with the other renderers, since it
turns out they're (currently) fundamentally incompatible.
