a0d85e33c2 [gamecode] Rework implementation of memset* 
The memset instructions now match the move* instructions other than the
first operand (always int). Probably breaks much, but fixed in next few
commits.

023a920a51 [gamecode] Replace lost parameter auto-reset 
rcallN messes with the progs parameter pointers and not resetting them
can cause incorrect data to be copied into the called function.

6c56e93fc8 [gamecode] Be more careful with temp strings 
If a temp string is found in the return slot, PR_FreeTempStrings won't
delete the string. However, PR_PopFrame was blindly stomping on the
possibly surviving temp string with the push strings, which would cause
a leak.

f290b115a5 [gamecode] Add function PR_PushTempString 
This "pushes" a temp string onto the callee's stack frame after removing
it from the caller's stack frame. This is so builtins can pass
auto-freed memory to called progs code. No checking is done, but mayhem
is likely to ensue if a string is pushed that was allocated in an
earlier frame.

7d43bd5c66 [gamecode] Add function PR_AllocTempBlock() 
PR_AllocTempBlock() works the same way as PR_SetTempString(), except
that it takes a size parameter and always allocates (never tries to
merge). This is, in a way, abusing the string system, but I needed a way
to allocate a block of progs memory that would be automatically freed
when the current frame ended. The biggest abuse is the need to cast away
the const of PR_GetString()'s return value.

c726d77e7d [gamecode] Respect the @float_promoted@ magic string 
Rather than relying on progs code version, use the string to determine
whether PR_Sprintf should behave as if floats have been promoted through
... I imagine I'll get to the rest of the server code at some stage.

With these two changes, nq-x11 works again (teleporters were the
symptom).

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.
 2020-02-26 19:30:10 +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.

225a375ab9 Extend the lifetime of return-strings 
This is done by putting the most recently used return-string at the end
of the queue for recycling.

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.
 2020-02-26 13:40:26 +09:00

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.

4c1b6ce76c Make pr_parse thread safe 
Or at least, conversion to property list is thread safe.

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).

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
Bill Currie
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.
 2020-02-25 14:40:03 +09:00
Bill Currie
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.

b173c35eb4 Rework progs debug to use the type encodings

4b7ecdf74a Make PR_Init take an instance to initialize

806af85447 Remove reference to ddef_t from progs.h

 2020-02-22 22:44:08 +09:00
Bill Currie
81083698a8 Move to using an in-memory form of ddef_t 
This allows the VM to work with extended ddefs transparently. It seems
to have uncovered a typedef alias relocation bug, though.

f5741a979e Implement parameter alignment in the engine 
The engine now requires non-v6 progs to store the log2 alignment for the
param struct in .param_alignment.

PR_EnterFunction is clearer and possibly more efficient.

float is promoted to double through ... for non-v6 code.
PR_Sprintf has custom param access via P_*, messed up doubles.

df7c08a010 Add support for doubles to Ruamoko 
Only as scalars, I still need to think about what to do for vectors and

0f5f2a125a Use a reliable reference for calculating progs offsets. 
Now that pr->zone can be null, it cannot be used as a reference. Fixes

61185813fa Cleaner handling of zone_size/zone. 2018-10-11 10:22:10 +09:00
Bill Currie
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.
 2018-10-11 10:06:48 +09:00

34bcf7faab Do a pure/const/noreturn/format attribute pass. 
I always wanted these, but as gcc now provides warnings for functions that

8fd5be0ee0 Fix a pile of sizeof goofs. 
While scan-build wasn't what I was looking for, it has proven useful

3efb0c538f Separate file search from loading.

99a8e8f228 Fix the jump instruction. 
The offset to compensate for st++ was missing.

Obviously, the code has never been tested.  Found while looking at the

7c1d9d2b84 Make the angle and light hacks optional. 
I'd forgotten that ED_ConvertToPlist mangled light into light_lev and
single component angle values into a vector. This fixes much of the
breakage in qflight (but not the light levels)
 2013-03-07 09:11:23 +09:00
Bill Currie
675db274a6 Use Sys_Error instead of PR_Error in ED_ConvertToPlist. 
ED_ConvertToPlist is now independent of the progs engine as its only use
for the progs_t * param was for PR_Error.
 2013-03-07 09:11:22 +09:00

3c67e8f020 Fix the vector/quaternion scaling instructions. 
It was pointed out by Blub\w (gmqcc) that OP_MUL_FV and friends were buggy
when the operands overlapped (eg, x = x.x * x) as the result would become
'x.x*x.x x.y*x.x*x.x x.z*x.x*x.x' (note the x.x squared for y and z). On
testing, sure enough the bug was present (and is a nice demonstration that
QF's VM does NOT have strict-aliasing bugs). As a very nice benefit: the
code produced by the fixes is actually faster than the broken version :).

The ruamoko code used for testing:
void (string fmt, ...) printf = #0;

vector foo (vector x)
{
    x = x * x.x;
    return x;
}

vector bar (vector x)
{
    x = x.x * x;
    return x;
}

int main ()
{
    vector x = '2 3 4';
    vector y = foo (x);
    vector z = bar (x);
    printf ("x=%v y=%v z=%v 2*x=%v\n", x, y, z, 2*x);
    return 0;
}

6b97967a68 Use g instead of e for the fp values. 
Need to up the precision by one due to the difference between g and e, but
much prettier. Might need to rename that function :P I wish I'd thought to

I should have done this a long time ago:P. This removes the really silly

6eb6b6c0ba Change pointer_t to unsigned and clean up the mess. 
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

11b991cf9d Print the error message before the state dump. 
Normally, the order doesn't matter, but when tracing code, it becomes very
difficult to tell where the trace ends and the dump begins. Printing the
message first puts the message between the trace and the dump: much easier
:)

34e3ac1468 Fix jumpb's operand types. 
Aliasing the jump table to an integer broke statement_get_targetlist with
the new alias def handling, and was really wrong anyway. I probably did
that due to being fed up with things and wanting to get qfcc working again
rather than spending time getting jumpb right.
 2012-12-05 22:20:55 +09:00

49ad301d3d Add improved memory checking to progs. 
With pr_boundscheck >= 2, pointer access will be checked against allocated

b8b626ee81 Change the int<->float conversion opcode string. 
Using "=" was rather confusing, so changing it to "<CONV>" seems to be a
good idea. As the string is used only for selecting opcodes at compile

106257d6e9 Allow reconstructed builtins to be found by name. 
Certain versions of qcc (fteqcc comes to mind :P) strip the names from
builtin functions. This breaks saved games that happen to have a builtin
function in a saved function variable. The earlier builtin name
reconstruction patch happened to fix the writing of save games for such
progs, and this one fixes the reading.

a9adc94aa8 Force builtin function descriptors to have a name. 
That is, the descriptors loaded from the progs file. Some compilers (eg,

6e0907a6b1 Delay the "too many entities" check. 
Rather than checking the raw edict count in the entities file against the
progs' max_edicts, check the allocated entity's number. This allows loading
of sophisticated maps (eg, digs04) that prune many of their entities.

bb065bd233 Be a little leniant with vector param stores. 
qcc always used vector stores to load values into the function parameters,
but if the location of the value is too close to the end of the global data
block (the vector spans the end of the block), it would trigger the bounds
check code. Thus, allow such instructions without a murmer, so long as it
actually is a parameter write.

d3c2afc5d7 Handle old global vector compontents. 
In the original save gave format, global vectors were saved as individual
components rather than as a single vector, using the _x/_y/_z tags on the
vector name. However, recent qfcc completely dumped vector components as
separate defs, so old save games would have trouble loading with progs
built with a recent qfcc. Thus, do the component translation if necessary.

2a2a431431 Register a complaint when the map has too many entities. 
I was wondering why that parrot was dead.

Not realizing that negke's coag3 map had too many entities really ruined
the pleasure of playing it, so it's best to treat such situations as an
error (max_edicts can be bumped up to 32000 if need be, but 2048 is plenty
for his map).

c3f41e3e69 new opcode: state.f. same as state, but takes a 3rd float operand to 
specify the step for calculating nextthink. accessed using
[frame, think, step] (state is [frame, think])

390ca99a92 first step to making qfdefs redundant. "standard" progs now get resolved 
staticly rather than looking up the defs. "broken" progs should now work.

b3f76e1e48 add some string builtins (only the basics for now, but enough to deal with 
temporary strings) and fix the game load/save menus.

9c92a916ff change the dict and array add functions to return true/false and add some 
more docs

e455b760ca use a cycled pool of "return strings". I'd love to come up with something 
better, but this will do (similar to what qwe does, but qf style:)

be modified

133879f8fa provide builtin mappings for id (none, really), qf and ktpro/qwe (qw only), 
add qwe builtin extensions to qw-server. provide sv_progs_ext to control
the builtin mapping. valid values are "id", "qf" (our old static builtins),
"qwe"/"ktpro" (either works. for ktpro mod support) and "none" (no
mapping). any other value is equivalent to "none".

d7592781d7 add builtin mapping support (not used yet) and fix an uninitialized 
variable

acd54afff7 move to using a hash table for builtin number -> builtin lookup so sparse 
ranges can be used efficiently. move the auto-allocated builtins to
0x10000000-0x7fffffff. should be more than enough :)

use static builtin tables ("nul" terminated) instead of a series of
function calls to add builtins to a vm. should be more memory efficient.

fbe6c2f631 make the bad builtin number a warning and provide a suitable function in 
case the function is called: allows progs with bad (but unused) builtins
to run anyway
