a906efac47 [ruamoko] Register protocols and their selectors 2020-03-02 15:20:34 +09:00
Bill Currie
78f552aa87 [ruamoko] Initialize static instances 
This is one step closer to implementing conformsToProtocol. However,
protocols are not yet initialized correctly: they are not registered,
nor are their selectors.

While the static initializer list pointer was not written previously,
the module struct always came immediately after the symbols struct, and
the module version has so far always been 0. Thus, the list pointer is
correctly 0 for older progs and there's no need for a version bump.

bc4bea79cb [ruamoko] Remove a stale FIXME 
This was fixed when pr_def_t was introduced. I missed the comment at the
time.

75f4cebf0e Clean up after removal of uint32.h 
I guess I forgot to check for its usage in header files, and the fact that
it didn't get cleaned out from being installed hid the error.

I had forgotten that it works only for dynamic strings.

c9186c8296 Clear the statement line buffer 
The problem with moving to a cached buffer is it needs to be cleared.
Fixes the weird output of qfprogs and tracing (not missing local defs,
though).

62b541793d [gamecode] Remove all use of va 
With this, the VA is very close to being safe to use in a threaded
environment (so long as each VM is used by only one thread). Just the
debug file hash and source paths to sort out.

ddd007e2d5 [dstring] Return the string instead of printed size 
Other than consistency with printf(), I'm not sure why we went with the
printed size as the return value; returning the resultant strings makes
much more sense as dsprintf() (etc) can then be used as a safe va()
 2020-02-26 19:00:19 +09:00
Bill Currie
36bc139b27 Avoid use of va in PR_Sprintf 
With this, progs strings are thread safe so long as only one thread
tries to use the VM.

383a7fe5e1 Remove File_Open 
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.

225a375ab9 Extend the lifetime of return-strings

aa02069dd1 Add a breakpoint flag to opcodes 
The progs execution code will call a breakpoint handler just before
executing an instruction with the flag set. This means there's no need
for the breakpoint handler to mess with execution state or even the
instruction in order to continue past the breakpoint.

The flag being set in a progs file is invalid.

d60291a73e Clean up a lot of va usage 
va is not thread-safe (it's not save even without threads), and I want
to be able to run progs in threads.

42713cad8b Make script much friendlier to use

an error.

35c9d6ee38 Make pr_obcode.c mostly thread safe 
Its public data is all read-only, and once set up, its private data is
too (just don't call init in multiple threads).

3577d27a45 Move the ObjQC data into a resource block 
This makes it nice and private (though with the cached pointer, ObjQC is
still a first-class component).

282132958f Relocate local def type encodings in debug load 
For technical reasons (programmer laziness), qfcc does not fix up local
def type encodings when writing the debug symbols file (type encoding
location not readily accessible).
 2020-02-25 20:46:01 +09:00
Bill Currie
89e83d7d73 Move the debug info out of progs_t 
The debug subsystem now uses the resources system to ensure it cleans
up, and its data is now semi-private. Unfortunately, PR_LoadDebug had to
remain public for qfprogs because using PR_RunLoadFuncs would cause
builtin resolution to complain.
 2020-02-25 20:07:29 +09:00

a55b9544ac Improve handling of pr_argc 
It is now set to 0 when progs are loaded and every time
PR_ExecuteProgram() returns. This takes care of the default case, but
when setting parameters, pr_argc needs to be set correctly in case a
vararg function is called.

6a4ef598ab Allow progs num_edicts and reserved_edicts to be null 
Really, while there are edict related instructions, edict support should
probably not be in the VM itself.
 2020-02-25 15:00:33 +09:00
Bill Currie
6e56c9a4aa Ensure edict_parse is reset on progs load 
A server switching from a game that sets edict_parse to one that does
not could go badly when it comes time to loading a level.

9bb68f2d8c Allow nested use of PR_SaveParams() 
PR_SaveParams() is required for implementing the +initialize diversion
used by Objective-QuakeC because builtins do not have local def spaces
(of course, a normal stack calling convention would help). However, it
is entirely possible for a call to +initialize to trigger another call
to +initialize, thus the need for stacking parameter stashes. As a
bonus, this implementation cleans up some fields in progs_t.

256dee98a1 Make progs string resources management private 
Strangely enough, using the progs resources system. This is a step
towards having progs that can be reset properly, or even dynamically
created VMs.

3720956d88 Speed up two of the three deletion cases 
The initial code was pretty much a port of the code in the editor I
wrote 25 years ago. Either I didn't think of the optimization back then,
or I tried to implement it, failed, and figured it wasn't worth it
(despite using it on a 386dx33). However, I noticed it now and it was
easy enough to get working, and it's always good to not do something
that's not needed.

4b7ecdf74a Make PR_Init take an instance to initialize

 2020-02-22 22:44:08 +09:00
Bill Currie
81083698a8 Move to using an in-memory form of ddef_t

2db5d04e3f Reduce the ephemeral nature of str_mid 
When the substring is the tail of the supplied string, return a
"pointer" to within the supplied string rather than a new "return"
string. This means that tail-end substrings of string constants are
themselves constants.

The better accuracy is for specific cases (90 degree rotations around a

seems to be faster than add for fp, at least in this situation).

d5cb432911 Add a cvar to block use of x11 vidmode 
Or really, allow it if the user specifically requests it: the default is
blocked. Modern systems (particularly displays) do not really like
changing resolution, so doing so by default seems rather wrong.

ed3c5cb9ec Add a strset "class" 
It's just a wrapper around hashtab, but it makes checking if a string is
in a set easy. Way overkill when only a few extensions are enabled, but
more might come later.

8ee06d75a9 Separate render and presentation initialization 
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.

cb10175824 Pass vid_internal to R_LoadModule 
This fixes the segfault and pushes things very much in the desired
direction of proper system independence for rendering and presentation
separation (though things were headed in the right direction before).

6ee2df8445 Move vid callbacks into vid_internal 
Currently segfaults because viddef is an alias for *r_data->vid, which
has not yet been initialized (chicken and egg).

Things are still a mess, but a proper cleanup will be a lot of work and
will, really, involve properly splitting quake-specific code* out from
the rest of the renderer.

ab08e4f207 Create a logical device with a single queue 
A single graphics-capable queue should be enough for now. However, I'm
not sure I'm happy with a lot of the code: it's a bit difficult to write
flexibly configured code for Vulkan (or seems to be at this stage),
especially in C.

f58c2fef5a Switch QF's quaterions from wxyz to xyzw. 
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).

82809eb856 Simplify the call to PR_LoadProgsFile. 
I've decided that setting pr.max_edicts and pr.zone_size as part of the
local progs initialization rather than in PR_LoadProgsFile makes more
sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.
