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.

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.

6c6433dea5 Fetch the def name only once when scanning 
Not that speed is critical at this point, but it feels better.

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

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.

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.

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.

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.

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.

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.

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.

6bc803c72d Use correct encoding for alias types 
I got confused which field was which.

6bcc2c49ab Use helper functions for type checks 
They hide the evil details of aliased types. More to come :/

d50a27a045 Race down the alias chain before checking types 
This takes care of some of the type aliasing issues.

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.

a6f3e1753a Fix ruamoko's hashtab_t typedef 
Being typedefed directly to a pointer is a holdover from when pointer
declarations were really awkward.

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.

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.

bd6dcafdc8 Replace system defines/includes with qfcc's 
Right now, it probably works only with modern gcc.

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.

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.
 2020-02-16 17:13:45 +09:00

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.
