b4aebc120e [qfcc] Treat { } as nil for initializing compound types 2020-02-27 20:30:39 +09:00
Bill Currie
7c9072aebf [qfcc] Create struct fields for "type typename" 
Such declarations were being lost, thus in the following, the id field
never got added:
typedef struct qwaq_mevent_s {
    int         id;
    int         x, y, z;
    int         buttons;
} qwaq_mevent_t;

edde4bad15 Create a basic hello world 
And it has begun. It has some problems, but worse, it seems I broke
qfprogs and maybe pr_debug.c.

126f8502bd Start working on a qwaq console tool

4cec3bbff6 Unalias types when checking cast-compatibility

69b5029de5 Throw away function parameter type alias info 
typedef is meant to create a simple renaming of a potentially complex
type, not create a new type. Keeping the parameter type alias info makes
the types effectively different when it comes to overloaded function
resolution, which is quite contrary to the goal. Does expose some
breakage elsewhere, though.

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.

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.

81293d98dd Fix qfo line info dumping 
The addition of xdef data has made qfo_to_progs unusable in qfprogs,

4df926e531 Write extended ddef information to progs far data

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.

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.

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.

 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

83fb588727 Support vector/quaternion division by float 
Implemented via v*(1/f) or q*(1/f) to give CSE a chance to optimize the

 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.

ef4ad52239 Make binary_expr fold constants

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.

I don't remember what the goal was (stopped working on it eight months

   about jai at the time)
 - something for pascal
 - simply that the default symbol type should not be var (in which case,
   goal accomplished)

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.

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.

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

bugs (allocating too much or too little memory).

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).

cb366dd825 Better flow dot dump "scripting". 
Not sure I want to keep the statements in the live dump, but the system
is more flexible now.
