ab04a1915e [build] Fix a pile of gcc 10 issues 
gcc got stricter about array accesses, complicating progs macros, and
much better at detecting buffer overflows.

cf7c4780eb [gamecode] Load extended debug data 
And add function to get a source file's base directory if available.

7bcfd2f2be [gamecode] Move file_hash into debug resources 
I don't remember why I didn't do this earlier when I thread-safed progs.

fbbe144399 [gamecode] Clean up some stray "struct" 
Left over from moving debug data from progs.h to pr_debug.c

f90613bc3a [gamecode] Rename fields in pr_stack_t 
s and f are a little too succinct.

ddec80edc1 [qfcc] Make type encoding union anonymous 
I'd do more, but things get messy with direct access to unions that I
want to be anonymous.

8b1e4eea58 [qfcc] Bring back the core of type aliasing 
No aliasing is done yet, but most of the infrastructure is there again.

4cef9792f4 [util] Make hash-tables semi-thread-safe 
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.

99f89840f9 [gamecode] Show containing def and relative offset 
No more guessing when accessing structure field members. Next is ivars,
I guess.

2f9f6d3aa9 [gamecode] Relocate aux function return types 
They are written with offsets relative to the type encodings base.

9492f08536 [gamecode] Print structs as well as unions 
Much better :)

fea6381574 [gamecode] Rework debug type handling a little 
Type encodings are used whenever they are available. For now, if they
are not, then everything is treated as void (which prints <void>, not
very useful). Most return statements and references to .return are now
very readable (excluding structs), and only params going through "..."
are a messy union.

a069fad41e [gamecode] Print only entity address when no edicts 
If the edicts pointer is null, it's not possible to convert the entity
address to an index.

6dfe37635d [gamecode] Dump union contents 
The output is messy, but better than <union>

and add some comments. took a bit to figure out what i was doing

4e4b553cc3 [gamecode] Take care of missed type alias stuff 2020-03-01 16:20:23 +09:00

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.

42713cad8b Make script much friendlier to use 
It now simply sets an error message pointer and returns false if there's
an error.

66dd3ef070 Make a bunch of count things positive-only 
This fixes a pile of FIXMEs, because some things should never be
negative.

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).

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.

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.

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.

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

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).

c25e68ecaf Use hex output for %E opcode format specifier. 
This makes %E's addresses consistent with other address output.

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.

ec42bde527 Make hash tables more const correct. 
And clean up the resulting mess :/

d73b5045d8 Do not do any contents evaluation if not printing contents. 
Fixes a segfault when tracing progs caused by the recent entity number
change.

23a38738fc Massive whitespace cleanup. 
Lots of trailing whitespace and otherwise blank lines.

bc1b483525 Nuke the rcsid stuff. 
It's pretty useless in git.

b5019c8e33 Nuke the engine dicrectory from gamecode. 
Not the contents, of course :) Anyway, finally, that totally useless
directory is gone.

47a6f2c9b5 pr_debug.c: 
capitolise CRC and add a \n to the message
sv_progs.c (both nq and qw):
	don't bother checking the progdefs.h crc: it's just not needed any more
pr_imm.c:
	use r instead of rep when checking the hash tables.
main.c (quaq):
	make developer work and set com_filesize (otherwise, progs crc doesn't
	get set properly (com_filesize, not developer:))
