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.
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The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.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.
