dda045bf96 Do lazy computation of def sizes from type encodings 
The size is calculated when needed and cached.

b173c35eb4 Rework progs debug to use the type encodings 
It's only a start: the output is, if anything, slightly worse than
before, but it does have the basics going.

4b7ecdf74a Make PR_Init take an instance to initialize 
This allows internal sub-systems to do per-instance initializations
without other engine systems having to know about them.

f8b1a3a89f Return the previous sys print callbacks 
This allows for temporary overrides.

806af85447 Remove reference to ddef_t from progs.h 
This cleans up some horrible names and redundant fields that were a
result of the transition to pr_def_t
 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.

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.

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.

b4fd804e4e Implement true modulo in the engine 2020-02-16 11:53:56 +09:00
Bill Currie
4269c8cb07 Rename the mod instruction to rem 
Because % really implements remainder rather than true modulo, and I
plan on adding %% to implement true modulo.

bab3752e98 Add missed overridden math functions 
And fix misspelled ones too.

2cd62fe01b Fix several double-related bug 
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
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.

13b608f40c Don't truncat float % float 
This allows full usage, eg, x % pi, but otherwise maintains
compatibility with integer %

de64be1d67 Show more info when dumping x11 video modes 
Found in an old stash. Probably the start of xrandr support.

6ce87497f3 Fix a potential buffer overflow 
Highly unlikely to have that many sub models, but it does keep gcc
quiet.

302a462c32 Make SetMouse timeout after 2 seconds 
This makes sure that some unchecked event doesn't cause a lockup.
However, blocking input is really not the way to go: need to implement a
state machine and use non-blocking event reads.

980cf58ac5 Wait for the window to be visible before mouse warping 
This fixes the hang during fullscreen startup on my system (the motion
events weren't being generated because there was no window to see the
motion).

a4f963f67b 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.

c727f6a130 Rewrite QuatMultVec to be faster 
Could be faster still using SSE, but that's another project.

f68129dc0f Try to use type encodings for function return type 
Now return statements in traces make much more sense.

0f5f2a125a Use a reliable reference for calculating progs offsets. 
Now that pr->zone can be null, it cannot be used as a reference. Fixes
random crashes when using qfprogs (random due to heap randomization).

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).

33cbc500e8 Fix a segfault when setting up the stack. 
Yup, putting {}s around even single statements under flow control (if, etc)
is a good idea. Wonder if there's a gcc warning for that...

6252faa069 Fix a size error in OP_LOAD_Q. 
C&P from OP_LOAD_V :/

364c2d2c2b Add a stack and push and pop instructions. 
The stack is for data, not return addresses.

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

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.

34bcf7faab Do a pure/const/noreturn/format attribute pass. 
I always wanted these, but as gcc now provides warnings for functions that
could do with such attributes, finding all the functions is much easier.

3f638d95ba Remove a possibly spurious break. 
I'm not certain despair actually meant for the break to be there. It
certainly would have sped up the game a bit but at the expense of proper
blood trails in the software renderers.

62793b2dc2 Fix some potentially garbage assignments. 
These are the ones where I could easily make scan-build happy. They do seem
to be potential holes where invalid data in one place could result in use
of uninitialized values.

8fd5be0ee0 Fix a pile of sizeof goofs. 
While scan-build wasn't what I was looking for, it has proven useful
anyway: many of the sizeof errors were just noise, but a few were actual
bugs (allocating too much or too little memory).

575a67b2a1 mat4 test case fixes. 
The tests cases themselves were buggy.

4f58429137 Fix an unhealthy pile of gcc 8 warnings. 
While some of the warnings were merely annoying, some where actual bugs or
unearthed bugs in related code.
