While qfcc will always align double values to 8 bytes (really, two
global words) regardless of the underlying hardware, gcc does not:
doubles are only 4-byte aligned on 32-bit hardware.
This fixes the invalid debug target handle when running on i686.
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).
I never liked that some of the macros needed the type as a parameter
(yay typeof and __auto_type) or those that returned a value hid the
return statement so they couldn't be used in assignments.
This is the first step towards component-based entities.
There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.
As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.
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.
I think I wasn't sure at the time whether the simple variable was
required for pthread_cond_wait (and friends) to work properly, but it
is: the time between the target posting the debug event and the target
waiting on the condition variable turns out to sometimes be enough for
the debugger to handle the event and signal the target to continue,
resulting in the target waiting on a signal that will never come because
another debug event will not be sent by the target until AFTER it has
exited from the debug handler.
Pressing F8 (or n) while the debug target was running would cause it to
stop at that point. While it's certainly desirable to stop a runaway
target on demand, that should be with a different input. Now, commands
that start the target running are ignored while the target is running.
No commands for when the target is running have been implemented yet,
but the provision is there.
Same issue as for the menus. But now I know why PR_LoadProgsFile is used
instead of PR_LoadProgs (at least for qwaq): avoidance of the gamedir
restriction (however, the menus are supposed to be restricted).
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).
I decided that stopping in between function calls that are on the same
line is a good thing as it gives a chance to skip over the first but
step into the second.
This allows a debugger to do any symbol lookups and other preparations
between loading progs and the first code execution. .ctors are called as
per normal if debug_handler is not set.
While this does answer the question of how I'll go about restarting the
target progs (when I get to that point), it was required just to start
full-on ruamoko progs because .ctor was getting run in the main thread
and blocking due to trace.
In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.
