Bill Currie 9c26d12f95 Cast rather than alias for testing constants 
Fixes ICE in do { ... } while (1);
 2020-02-24 02:13:23 +09:00
Bill Currie 55e53211e2 Generate default type expressions for folded booleans 2020-02-24 02:11:31 +09:00

 2020-02-24 00:22:13 +09:00
Bill Currie 11365024d2 Fix writing of frames files when not requested 
I forgot to check for the option for separate compilation.
 2020-02-24 00:07:48 +09:00
Bill Currie 27ae5ccfce Fix ICE after incomplete type error 
Attempting to define a variable with an incomplete type is an error, and
results in a default size 1 of allocated, but I forgot to set default
alignment when implementing alignment.
 2020-02-24 00:07:39 +09:00
Bill Currie f387b9aa47 Propagate implicit for negating double constants 2020-02-23 23:41:12 +09:00
Bill Currie 5374798ef9 Fix order of operations for implicit casts 2020-02-23 23:18:31 +09:00
Bill Currie 05f6ddbb13 Print promoted warnings as errors 
This makes it much easier to see why a compilation failed when only
warnings are visible.
 2020-02-23 23:10:56 +09:00
Bill Currie 526c27cf03 Handle implicit casts for double/float comparisons 2020-02-23 23:10:10 +09:00
Bill Currie 607fd2e30e Allow constant initialized globals in advanced code 
Use -C const-initializers to enable (or no-const-initializers to disable
in traditional/extended code).
 2020-02-23 22:51:00 +09:00
Bill Currie e23aa40994 Implicitly cast unadorned floating point constants 
Floating point constants without f or d adornments will automatically
cast, without warnings, to the type appropriate to the rest of the
expression.
 2020-02-23 22:28:54 +09:00
Bill Currie 14cde99d6e White space 
of the worst sort.
 2020-02-23 22:27:07 +09:00
Bill Currie ea3af84baa Fix ICE when const-folding doubles 
I really need to rework that system.
 2020-02-23 20:49:56 +09:00
Bill Currie 2a39208069 Set void alignment to 1 
qcc allowed void variables.
 2020-02-23 20:48:43 +09:00
Bill Currie c9fca9c98a Fix another inside-out type utility function 2020-02-23 20:48:12 +09:00
Bill Currie 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.
 2020-02-23 18:32:16 +09:00
Bill Currie 6009d1d023 Fix qfo strings dumping 2020-02-23 15:08:31 +09:00
Bill Currie b0157e5095 Fix qfo field dumping 2020-02-23 14:56:50 +09:00
Bill Currie 81293d98dd Fix qfo line info dumping 
The addition of xdef data has made qfo_to_progs unusable in qfprogs,
resulting in various invalid memory accesses. It always was an ugly hack
anyway, so this is the first step to proper qfo support in qfprogs.
 2020-02-23 14:44:25 +09:00
Bill Currie 155a633ebe Include extended defs data in the size report 2020-02-23 11:53:57 +09:00
Bill Currie 6c6433dea5 Fetch the def name only once when scanning 
Not that speed is critical at this point, but it feels better.
 2020-02-23 11:52:35 +09:00
Bill Currie 52d54f98bf Fix some issues in the typedef test 
It wasn't being strict enough in the test (but was good enough to catch
the relocation error, at least) and was printing the alias name
incorrectly.
 2020-02-22 23:41:09 +09:00
Bill Currie 3aabfa71d9 Find lost type encoding relocations 
I have no idea why I thought it was a good idea to delete those lines.
Yay for regression tests, though.
 2020-02-22 23:33:56 +09:00
Bill Currie 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.
 2020-02-22 22:33:44 +09:00
Bill Currie 4df926e531 Write extended ddef information to progs far data 
I was originally going to put it in the debug syms file, but I realized
that the data persistence code would need access to both def type and
certainly correct def offsets for defs in far data.
 2020-02-22 14:11:15 +09:00
Bill Currie e7b4eedc07 Fix segfault in dereferencing undefined field containers 2020-02-22 14:04:10 +09:00
Bill Currie c296514b95 Make pr.load_file 'return' the file size 2020-02-21 21:17:28 +09:00
Bill Currie 7e76a96f7d Fix a missed ty_none 2020-02-21 21:13:18 +09:00
Bill Currie fe796eee68 Move the meta type enum ino pr_type.h 2020-02-21 17:58:19 +09:00
Bill Currie 8b225dbfc1 Ensure .ctor functions do not reset tracing 2020-02-21 17:53:27 +09:00
Bill Currie caf78b5422 Rename ty_none to ty_basic 
This far better reflects the actual meaning. It is very likely that
ty_none is a holdover from long before there was full type encoding and
it meant that the union in qfcc's type_t had no data. This is still
true for basic types, but only if not a function, field or pointer type.
If the type was function, field or pointer, it was not true, so it was
misnamed pretty much from the start.
 2020-02-21 17:52:00 +09:00
Bill Currie 1b43046c8a Handle aliased types when building function calls 2020-02-19 21:41:46 +09:00
Bill Currie fd2b7ee6f9 Use more type checking helper functions 2020-02-19 21:41:46 +09:00
Bill Currie a6003ed08a Walk qfo alias chain for type size and alignment 
While the basic type is stored in the alias type record, it's no good
for size or alignment as it will give incorrect results for complex
types.
 2020-02-19 21:41:46 +09:00
Bill Currie a0914e1ec8 Fix the typedef test case to actually work 2020-02-19 21:41:46 +09:00
Bill Currie 6a70d2e362 Give alias types a unique encoding 
The encoding is used as the def name and it needs to be different than
the alias target or the linker throws it away as an external def.
 2020-02-19 21:41:46 +09:00
Bill Currie 6bc803c72d Use correct encoding for alias types 
I got confused which field was which.
 2020-02-19 21:41:46 +09:00
Bill Currie 6bcc2c49ab Use helper functions for type checks 
They hide the evil details of aliased types. More to come :/
 2020-02-19 21:41:46 +09:00
Bill Currie 9610788dea Fix some more type aliasing issues 
Getting there... (I knew this would be a big job)
 2020-02-19 21:41:46 +09:00
Bill Currie d50a27a045 Race down the alias chain before checking types 
This takes care of some of the type aliasing issues.
 2020-02-19 21:41:46 +09:00
Bill Currie a5aba6c8ac Implement type aliasing 
The separate types are in the file, but there are multiple issues
 2020-02-19 21:41:46 +09:00
Bill Currie 2f18364364 Start work on encoding typedef chains 2020-02-19 21:41:46 +09:00
Bill Currie adb7f5d601 Quieten the test script build rules 2020-02-19 21:41:46 +09:00
Bill Currie b00c866c4e Allow casting between string and pointer types 2020-02-19 21:41:46 +09:00
Bill Currie 7a315b4a89 Fix storage class for for-loop declarations 
Getting "i redeclared" when i was declared in a for loop in two
different functions was a tad unexpected.
 2020-02-19 21:41:46 +09:00
Bill Currie 4c40928112 Remove what appears to be a redundant check 
It was long wrong anyway as it checked past the end of the function's
parameters, which caused a segfault when calling varargs functions with
no formal parameters.
 2020-02-19 02:53:38 +09:00
Bill Currie a65d6bce09 Fix a warning that got through 
I forgot to compile test in optimized...
 2020-02-19 02:43:27 +09:00
Bill Currie bd6dcafdc8 Replace system defines/includes with qfcc's 
Right now, it probably works only with modern gcc.
 2020-02-19 02:35:09 +09:00
Bill Currie 2d52da9c0d Fix segfault in unlimited params 2020-02-19 02:35:09 +09:00
Bill Currie c61d0b6ff0 Allow unlimited parameters in function declarations 
However, definitions are still limited to 8 parameters. This allows
processing of C headers for type information.
 2020-02-19 02:35:09 +09:00
Bill Currie ee228504aa Fix self-referenced enum declarations 
eg:
typedef enum foo {
    bar = 1,
    baz = bar,
} foo;
 2020-02-19 02:35:09 +09:00
Bill Currie 7a399c956b Encode function parameter alignment 
The encoding is 3:5 giving 3 bits for alignment (log2) and 5 bits for
size, with alignment in the 3 most significant bits. This keeps the
format backwards compatible as until doubles were added, all types were
aligned to 1 word which gets encoded as 0, and the size is unaffected.
 2020-02-16 17:10:43 +09:00
Bill Currie 1bc08c59f6 Add tests for %% 
double fails due to qfcc aligning double param locals, but the engine
not doing so.
 2020-02-16 17:02:38 +09:00
Bill Currie 1a9510834a Add a missed opcode conversion for %% 2020-02-16 12:10:09 +09:00
Bill Currie 9d2d33fa50 Implement %% (true modulo) support in qfcc 
However, it's not quite working yet
 2020-02-16 11:57:58 +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.
 2020-02-16 11:04:30 +09:00
Bill Currie db9996023f Add some tests for double comparison 
More testing the engine than the compiler, but hey :)
 2020-02-15 23:49:12 +09:00
Bill Currie 14acfad7c4 Fix incorrect placement of far data 
All the care in aligning things was undone by not updating the
calculations of the pointers.
 2020-02-15 23:49:12 +09:00
Bill Currie 1985b6d4fd Avoid creating a struct temp for ivar struct return 
This fixed the uninitialized temp warning in HUD.r. The problem was
caused by the flow analyzer not being able to detect that the struct
temp was being initialized by the move statement due to the address of
the temp being in a pointer temp. While it would be good to use a
constant pointer for the address of the struct temp or improving the
flow analyzer to track actual data, avoiding the temp in the first place
results in nicer code as it removes a move statement.
 2020-02-15 23:49:12 +09:00
Bill Currie 9c996df7b4 Add a test case for the uninit temp in HUD.r 2020-02-15 23:49:12 +09:00
Bill Currie 7bfa0f7a92 Allow pragmas to have arguments 
It does mean only one pragma per line, but that's not such a big deal.
 2020-02-15 23:49:12 +09:00
Bill Currie 91f5023681 Promote bugs to internal errors 
Mostly so I can catch them in test cases
 2020-02-15 23:49:12 +09:00
Bill Currie 344d429134 Test array initializer double demotions 
Turns out array inits are very strict about types (bug?).
 2020-02-15 23:49:12 +09:00
Bill Currie 6ce99afa5b Catch double demotion in global initializers 
Local initializers are handled by regular assignments
 2020-02-15 23:49:12 +09:00
Bill Currie c5ce18591f Catch and warn demotion of double in assignments 2020-02-15 23:49:12 +09:00
Bill Currie 08ca59d0df Add tests for double demotion 2020-02-15 23:49:12 +09:00
Bill Currie 4bf37b274b Ensure double is not in zero or param structs for v6 2020-02-15 23:49:12 +09:00
Bill Currie be30a0eb19 Fix missing alignment init on zero and param types 2020-02-15 23:49:12 +09:00
Bill Currie 3e651b43f8 Handle aliased values when emitting statements 
With this, cast address initializers work. I have to wonder if the alias
value short-circuit was legacy from long before the rewrite, as it was
quite trivial to handle in the back-end.
 2020-02-15 23:49:12 +09:00
Bill Currie e4eb793fb3 Treat aliased values as constant 
One step closer to cast address initializers working.
 2020-02-15 23:49:12 +09:00
Bill Currie ce9902baed Don't short-circuit aliased values 
Not sure why I thought it was a good idea as it turns out this is why
cast pointer initializers were being lost.
 2020-02-15 23:49:12 +09:00
Bill Currie 3257e7145b Add failing global init test too 2020-02-15 23:49:12 +09:00
Bill Currie 4caa875442 Finish up alignment tests and add address cast 
It turns out that initializing a local int with a pointer cast doesn't
work.
 2020-02-15 23:49:12 +09:00
Bill Currie a4a57b6ffd Implement aligned allocations 2020-02-15 23:49:12 +09:00
Bill Currie 293f10211a Start on alignment test 
Currently fails (deliberately, WIP)
 2020-02-15 23:49:12 +09:00
Bill Currie 0542daacdf Create more double related tests 
Including catching warnings :) (yay -Werror)
 2020-02-15 23:49:12 +09:00
Bill Currie 7e09a94469 Fix "casts" between signed and unsigned int 2020-02-15 23:49:12 +09:00
Bill Currie 5d8d805b60 Fix test for single overload functions 
All functions are stored in the overload functions table, even those
that are never explicitly overloaded, but only explicitly overloaded
functions (those with @overload) use the type-qualified naming.
 2020-02-15 23:49:12 +09:00
Bill Currie 533fb8acc9 Implement double constants 2020-02-15 23:49:12 +09:00
Bill Currie 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.
 2020-02-15 23:49:12 +09:00
Bill Currie eb7f825158 Test for full-float % 2020-02-15 23:49:12 +09:00
Bill Currie 8920c59515 Find @override functions even when there's only one 2020-02-15 23:49:12 +09:00
Bill Currie 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.
 2020-02-15 23:49:12 +09:00
Bill Currie 13b608f40c Don't truncat float % float 
This allows full usage, eg, x % pi, but otherwise maintains
compatibility with integer %
 2020-02-15 23:49:12 +09:00
Bill Currie 16f8dca72e Align local and far data spaces 
I plan on adding doubles, and so it's necessary to ensure that attempts
to align doubles in local or far data spaces remain aligned after final
linking.
 2020-02-15 23:49:12 +09:00
Bill Currie 197f856a30 Fix incorrect scalar/quaternion division 
It's just not possible.
 2020-02-15 23:49:12 +09:00
Bill Currie 9248e8cf01 Update for doxygen 1.8.16 2020-02-11 15:22:42 +09:00
Bill Currie c3fa78ef4d Include test for 2d vector expressions 2019-07-06 14:49:28 +09:00
Bill Currie 8caf2eb584 Mark some new functions as pure 2019-06-27 21:37:48 +09:00
Bill Currie a5ee58cebb Support 2d vector expressions 
[x, y] expands to [x, y, 0] (for now, might add a 2d vector type).
 2019-06-18 11:54:45 +09:00
Bill Currie 83fac13a0c Fix debug line numbers for vector expressions 2019-06-18 11:53:58 +09:00
Bill Currie b37c331e76 Catch taking size of null type 
This should help catch similar errors in the future.
 2019-06-18 10:39:17 +09:00
Bill Currie 0f1f477e64 Set up temp aliases correctly 
Fixes vector expressions as sub-expresses. I really don't know why I did
the temp alias setup that way.
 2019-06-18 10:38:19 +09:00
Bill Currie fc50376297 Fix a minor error check mistake 2019-06-18 08:54:18 +09:00
Bill Currie fe73547f43 Update alias type sameness check 
This one seems to be fairly robust. Fixes alias being used to cast
pointers (maybe a better way, but this works for now).
 2019-06-18 08:53:05 +09:00
Bill Currie f7825fe7cf Print types properly in pointer value expressions 2019-06-18 00:22:24 +09:00
Bill Currie b996fb7aa4 Make operand->type actual type instead of low-level 
And clean up the resulting mess. This fixes struct copy, but uncovers
another bug :/
 2019-06-17 23:38:34 +09:00
Bill Currie e0c8285f07 Extend nested struct test to cover struct copy 
Fails :P
 2019-06-17 22:57:40 +09:00
Bill Currie dd52b7fea1 Merge aliased alias expressions 
This comes up when accessing struct fields nested in another struct.
Fixes the nested struct fields test.
 2019-06-17 22:48:42 +09:00
Bill Currie e9c24dbf1c Test case for accessing nested struct fields 
Currently fails.
 2019-06-17 22:47:44 +09:00
Bill Currie ec128ffeee Leave a FIXME for daglabel_t.live 2019-06-16 19:24:19 +09:00
Bill Currie d6d3027411 Mark the correct operand as live 
This fixes vecexpr (and possibly other cases).
 2019-06-16 19:21:02 +09:00
Bill Currie 6e21c3ae2e Treat func statements similarly to flow statements 
func statements need their operands marked live like flow statements do
because usage is more indirect.
 2019-06-16 19:20:21 +09:00
Bill Currie db4a7a139e Use the alias code when making vars live 
Not sure the live forcing flag is needed anymore (need to test).
 2019-06-16 19:17:45 +09:00
Bill Currie 2977c145d0 Clean up dag live alias code a little 
Mainly, this makes it possible to reuse the alias code.
 2019-06-16 19:17:01 +09:00
Bill Currie 82b334e919 Number dot dumps to help identify order 2019-06-16 19:12:18 +09:00
Bill Currie c40f4194e9 Use tempop_visit_all for flow and dags 
Fixes t3 of vecexpr, but t2 is broken (lost first assignment).
 2019-06-16 16:56:39 +09:00
Bill Currie 3c4903245a Fix some curly space 2019-06-16 16:55:54 +09:00
Bill Currie bc271d8a02 Add tempop_visit_all 
Works the same as def_visit_all, but for temp operands.
 2019-06-16 16:52:49 +09:00
Bill Currie fa69aeef0f Improve handling of temp aliases 
This makes all tests pass when not optimizing. More work needs to be
done in dags.
 2019-06-12 00:37:02 +09:00
Bill Currie b18a744288 Use offset alias expressions 
They are not quite working yet as the operand generator does not use the
offset yet.
 2019-06-10 23:55:16 +09:00
Bill Currie cc27949a34 Ensure pointer values always have a type 
The dags generator was creating a pointer value with no type which
caused print_statement to segfault.
 2019-06-10 23:52:39 +09:00
Bill Currie ee1f5f9478 Add support for binary alias expressions 
Doesn't quite work yet.
 2019-06-10 23:48:58 +09:00
Bill Currie 913b9f52e0 Add an offset alias expression 
This should make dealing with def elements (vector etc) easier.
 2019-06-10 18:13:28 +09:00
Bill Currie efdfc7436f Move ev_types into types.[ch] 
No wonder I couldn't find it the other day...
 2019-06-10 18:04:25 +09:00
Bill Currie 08ab42fc15 Handle vector expressions as sub-expressions 
Now my little game builds again :)
 2019-06-10 15:50:35 +09:00
Bill Currie 49ed4310fd Fix assigning int to enum or enum to int 
Or float, for v6 progs.
 2019-06-10 08:46:40 +09:00
Bill Currie 83fb588727 Support vector/quaternion division by float 
Implemented via v*(1/f) or q*(1/f) to give CSE a chance to optimize the
division if necessary as otherwise the engine would have to divide every
time.
 2019-06-10 08:44:36 +09:00
Bill Currie 7dc1a0640a Delay creating actual enum symbols 
In order to keep enumerator type and enum type the same, the values need
to have their type set after the enum type is finalized, and then the
appropriate symbols created in the parent scope. This fixes the infinite
recursion when assigning an enum value to its own type.
 2019-06-10 07:44:23 +09:00
Bill Currie f81484a068 Test compiling enums 
It turns out the enumerator type and enum type wind up with different
instances of the same type (due to the way type chaining works). This
results in infinite recursion in assign_expr and check_types_compatible.
 2019-06-10 07:17:41 +09:00
Bill Currie ef4ad52239 Make binary_expr fold constants 
This is where constant folding should have happened all along. While
unary_expr should fold constants too, it seems to already try to do so
and it's a bit much of a mess to clean up right now.

Bill Currie 3196bcc851 Allow fold_constants to handle some math identities 
Such as x*0 -> 0, x*1 -> x, x+0 ->x, etc.
 2019-06-09 22:34:23 +09:00
Bill Currie c98d1ff08c Document some problems with nil 
While he's a pretty cool character in HZD, he seems to have some
identity problems when in a compiler.
 2019-06-09 22:29:51 +09:00
Bill Currie 439cd15620 Do type promotion for short 
fold_constants used to do this when it was overly aggressive. Fixes the
ICE when accessing an array in a struct via a pointer.
 2019-06-09 22:27:53 +09:00
Bill Currie 227ac46ffe Clean up array expression processing 
And make sure constants are folded since fold_constants is no longer
recursive.
 2019-06-09 22:25:55 +09:00
Bill Currie f70801fa52 Add a test for accessing an array in a struct 
That's accessed via a pointer. Whee. However, at this stage, the problem
is really a promotion issue for short -> integer.
 2019-06-09 21:44:58 +09:00
Bill Currie e46a44d9c6 Update TODO 2019-06-09 21:37:46 +09:00
Bill Currie 6253623e9b Remove some weird dereference code 
It appears to have been an attempt at optimizing dereferences, but it
instead just utterly mangled them.
 2019-06-09 21:37:46 +09:00
Bill Currie f49303e774 Emit code for address expressions 
It helps if the necessary code is actually emitted in the first place.
 2019-06-09 21:37:46 +09:00
Bill Currie 8cef85e5de Cast scalar types when necessary on assignment 
This fixes type promotion errors that broke some tests.
 2019-06-09 20:12:50 +09:00
Bill Currie e849c2d1ce Mark block expr result as rvalue when used as one 
At least for return. There may be other cases that need it, but this
fixes comma-expr.r (minus int->float promotion issues).
 2019-06-09 19:29:21 +09:00
Bill Currie d9c9686288 Make initialized globals non-constant 
This is for modern code. Traditional code still treats initialized
globals as constant and nosave. This will make a bit of a mess of
modern code that expects traditional behavior.
 2019-06-09 19:23:23 +09:00
Bill Currie b7b6a89b91 Simplify fold_constants 
While this does break automatic type promotion, it does stop
fold_constants recursing through complex expressions: only the top level
expression needs to be folded, and then only if both sides are actually
constant.
 2019-06-09 19:20:35 +09:00
Bill Currie 2ee36e8b99 Rename qfot_type_t.ty to meta 
When I did up a ruamoko implementation of a type encoding dumper, I
named the field meta, which feels much better than ty.
 2019-06-09 18:10:07 +09:00
Bill Currie f093516962 Move qfo type encoding structs 
This makes them available to the gamecode VM, and thus the debugger.
 2019-06-09 18:07:58 +09:00
Bill Currie 7fce68649a Implement comma expressions 
Doesn't quite work (attempt to suppress warning for return a = 3, 5;

The multiple expressions are chained together and evaluate in left to
right order.
 2019-06-09 13:54:03 +09:00
Bill Currie d29ea55826 Add a test for for loop declarations 
I think the compiler segfaulting indicates a test failure.
 2019-06-09 13:02:36 +09:00
Bill Currie 625e767684 Update qf dependency stuff for recent automake 
Not sure just what version of automake broke things, but I do remember
having a bad time getting the dependencies to work in the first place.
At least now they should be more reliable (until automake changes
things).
 2019-06-09 13:00:55 +09:00
Bill Currie 5bd3c8c985 Allow variable declarations in for loops 
Matches C, C++ and C#
 2019-06-08 21:52:17 +09:00
Bill Currie be4c3a82a2 Detect redefinitions of structs and unions 
While the redefinition was being detected, it was misreported as the tag
being wrong, and on the wrong line, too.
 2019-06-08 19:25:25 +09:00
Bill Currie f2102187b9 Clean up emit_protocol_list 
Now it uses emit_structure, which will make it easier should things go
wrong.

Bill Currie e217bdd55f Assign vector expressions to a temp for return 
Rather than direct to .return, allowing return of vector expressions
with function calls without trashing the vector.
 2019-06-08 13:36:03 +09:00
Bill Currie ebab6574b9 Allow taking the address of a temporary variable 2019-06-08 13:35:47 +09:00
Bill Currie e27da9c7db Avoid folding constants in assign_expr 
This prevents fold_constants from complaining about attempts to take
the address of a vector.
 2019-06-08 13:31:30 +09:00
Bill Currie 398e1cf83a Use output file as base for dot files 
Ensures the output goes not go into the source directory when using a

Bill Currie 4ef4a7e955 Start work on simple names in symbol tables 
I don't remember what the goal was (stopped working on it eight months
ago), but some possibilities include:
 - better handling of nil (have trouble with assigning into struts)
 - automatic forward declarations ala C# and jai (I was watching vids
   about jai at the time)
 - something for pascal
 - simply that the default symbol type should not be var (in which case,
   goal accomplished)

Bill Currie 319ecfbbfa Create a usable dot for vector expressions 
It leaves a lot to be desired, but it beats "FIXME".
 2019-06-06 06:42:31 +09:00
Bill Currie 607ec3124e More dead code removal. 
I have no idea why this hung around. It appears to be old array/struct
initialization.

Bill Currie 6c53be928b Support returning vector expressions. 
Currently fails due to a scheduling problem when the vector expression
contains functions.
 2018-10-13 23:32:53 +09:00
Bill Currie aaab18c9a7 Nuke a dead field. 
It looks like ex_temp_t.expr was never really used, and I have no idea
what I had intended (not surprising after ~17 years).
 2018-10-13 12:07:50 +09:00
Bill Currie 2f2edae43b Make error, warning and notice give compiler file/line too. 
But only when verbosity > 1 (-vv).
 2018-10-13 09:31:00 +09:00
Bill Currie 4828934e50 Fix a equality check typo. 
Fixes bad code generation when assigning to vector.x in a function with no
parameters and the vector is the first local var.
 2018-10-12 23:39:05 +09:00
Bill Currie 78e0a8dc52 Support assigning non-constant vector expressions. 2018-10-12 22:05:17 +09:00

Bill Currie 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).
 2018-10-12 14:33:55 +09:00
Bill Currie b7aa5bb8fe Fix an oops messing up edict size. 2018-10-12 14:33:26 +09:00
Bill Currie f8606ebab8 Fix a object file segfault when spaces have no data. 
ie, don't attempt to copy memory from a null pointer (just copy the null
pointer).

Bill Currie 3bd9f96b07 Make internal error messages a little more helpful. 
They now include the file and line of the compiler as well.

Fixes some double-free bugs when linking after compiling.
 2018-10-11 21:37:01 +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
Bill Currie 673b45be05 Add diagnostic hooks. 2018-10-09 12:46:13 +09:00

Bill Currie 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.

This will make it easier to hook diagnostics enabling unit tests.

Not sure how this fix got lost.

Some were actual bugs!
 2018-09-08 22:23:57 +09:00
Bill Currie 59b04dbcca Make many qfo int fields unsigned. 
I don't remember why I thought signed was a good idea, but unsigned does
make more sense for most fields.
 2018-09-08 19:45:19 +09:00

Bill Currie 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).
 2018-09-07 20:00:57 +09:00
Bill Currie b37b0180cb Actually do a test for triangle.r. 
If the kahan triangle area method breaks, I did something wrong with qfcc's
handling of parentheses (ie, floating point math is not truly associative).
 2018-08-23 20:52:32 +09:00
Bill Currie 1b9149ef31 Fix an argument passing error in test-harness. 
It failed to pass the last argument to the ruamoko program being run.
