This fixes the mightsee updates never occurring, but it doesn't make a
huge difference (though I suppose it might have back in the 90s, or with
a different map).
The stats were being updated before UpdateMightsee was getting called,
and it was incrementing the wrong value (so it would not have been
thread-safe).
While whether it's any faster is debatable (it's slightly slower, but
many more portals are being tested due to different rounding in the base
vis stage), it's certainly easier to read.
While the main bulk of the improvement (36s down from 42s for
gmsp3v2.bsp on my i7-6850K) comes from using a high-tide allocator for
the windings (which necessitated using a fixed size), it is ever so
slightly faster than using malloc as the back-end.
This is for the conversion /to/ paletted textures. The conversion is
necessary for csqc support. In the process, the conversion has been sped up
by implementing a color cache for the conversion process. I haven't
measured the difference yet, but Mr Fixit does seem to load much faster for
the sw renderer than it did before the change (many months old memory).
The server edict arrays are now stored outside of progs memory, only the
entity data itself (ie data accessible to progs via ent.fld) is stored in
progs memory. Many of the changes were due to code accessing edicts and
entity fields directly rather than through the provided macros.
Double benefit, actually: faster when building a fat PVS (don't need to
copy as much) and can be used in multiple threads. Also, default visiblity
can be set, and the buffer size has its own macro.
Sort of at the request of leileilol (a utility to create quakepal.py was
asked for, but this seems to be better approach). However, the feature is
not used yet (needs hooks in the import and export modules).
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.
Block expressions hide ex_error, but get_type() always returns null when
it finds one (which it does by recursing into block expression), so just
check the type itself.
When a global variable is accessed via only an alias in a function the
actual def's flowvar would remain in the state it was from the last
function that accessed the global normally. This would result in invalid
flowvar accesses which can be difficult to reproduce (thus no test
case).

There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
This should keep things nicely extensible, since additional data can be
done in the data space and found using defs. This gets the compilation
units into the sym file.
They worked well if there was only one source file in the test, but
failed if there were two or more. While only typelinker needed the
enhanced macros, I got them all because I generally copy the nearest
block when adding a new test thus it's best if they're all "correct".
The compilation unit stores the directory from which qfcc was run and
any source files mentioned. This is similar to dwarf's compilation unit.
Right now, this is the only data in the new debug space, but more might
come in the future so it seems best to treat the debug space separately
in the object files.
getcwd is assumed to use malloc if its buff param is null. This may need
fixing in the future, but it's in one spot. The result in "saved" in the
non-progs pool.
It never really helped sort out the path issues when using build
directories. It worked well enough for single directory projects, but
things got messy very quickly, especially when mixing ruamoko libs with
external progs. A better method based on dwarf is coming.
Killed nodes can leave stray (dangling) edges that cause some confusion
in the dot graphs and may cause problems later on down the track, so
ensure there are no dangling edges.
The reason double-alias fails is when the double assignment occurs, the
int operands don't yet have leaf nodes and thus the nodes cannot be
killed. This doesn't fix the bug.
I'm not sure if it's due more to doubles or unions, but the bug was
found via double. It seems the dags code generator doesn't see that the
assignment to the union's double field kills the two int fields.
The test passes when NOT optimizing.
Because type aliases need to be unaliased, the type pointers in the type
encodings need to be correct when it comes to linking defs and
functions. This fixes the linking errors in ruamoko/game.
I was very uncertain about the validity of messing with the old type
encoding that way, but adding the check to ensure the type has been
processed never fired, so it seems ok. And the comments help me a lot :)
When aliasing a type that already has aliases, the top node needs to be
replaced if it is unnamed, or the alias-free branch of the new node
needs to reach around to the alias-free branch of the existing node.
This fixes the bogus param counts in qwaq.
This fixes the typelinker test, but not the linking error in
ruamoko/game that it was supposed to represent. I guess there's
something more going on (maybe type encoding relocation issues).
Fixes#6
It turned out that the problem with @zero was caused by initial type
chaining occurring before the structures had been initialized and thus
the linker's @zero type encoding string was incorrect: {?=} instead of
{tag @zero-}, thus when the actual type encoding supplied by an object
file came along (with the correct encoding string), it wasn't found.
It is now "consistent" with the rest of the type building in that it
uses find_type(append_type(return, params)) like the C version, thus
allowing append_type to do its thing with type aliases. This fixes the
overload test.
This is a bit of a weird one because it's a combination of the aliasing
code and mixing C prototypes with QuakeC function definitions, and the
function type rebuilding in qc-parse.y not being very "consistent" in
its abuse of the type system.
The full_type branch of an alias splitter (alias with null name) needs
to mirror the clean side up to the type alias. It is causing problems
with functions, but that's expected because parameters complicate
things.
It's not connected up yet because I'm unsure of just where to put things
(it gets messy fast), but just being able to see the structure of
complex types is nice.
This eases type unaliasing on functions a little.
Still more to to go, but this fixes a really hair-pulling bug: linux's
heap randomiser was making the typedef test fail randomly whenever
typedef.qfo was compiled.
When a type is aliased, the alias has two type chains: the simple type
chain with all other aliases stripped, and the full type chain. There
are still plenty of bugs in it, but having the clean type chain takes
care of the major issue that was in the previous attempt as only the
head of the type-chain needs to be skipped for type comparison.
Most of the bugs are in finding the locations where the head needs to be
skipped.
All simple type checks are now done using is_* helper functions. This
will help hide the implementation details of the type system from the
rest of the compiler (especially the changes needed for type aliasing).
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.
and its usage. The parts of flow_analyze_statement that use it know
where the returned operand needs to go. Unfortunately, this breaks dags
pretty hard, but that's because dags needs to learn about the fancy
assignment-type statements.
I noticed that pointer math is currently incorrect in qfcc, but it would
be nice for fixing it to not break anonstruct since it is testing
something else.
