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.
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.
This is the first step in reworking PR_Sprintf to use a state machine.
The goal is to make it more robust against errors and easier to extend
(eg, * width and precision).
Putting it in Editor worked as a proof of concept, but it seems those
always turn out to need tweaking like this because the concept proves
itself to be generally worthwhile :P
Leaking memory. And worse, it wasn't drawing its buttons (group wasn't
setting view contexts) and then the buttons were in the wrong place, so
had to add a backing buffer for the buttons.
This puts a print command (to Sys_Printf) into the queue making it
easier to check command sequences since regular printf is asynchronous
with the stream.
It currently dies when single stepping or exiting due to EditBuffer's
retain count not getting incremented when initialized. This is because
EditBuffer is initialized in C and thus does not call Object's -init.
While trying to build a view without deriving from it was a neat idea,
it doesn't work so well because a view really needs to know how to draw
itself. This even fixes the segfault when stepping past the end of the
program.
For now it just manages type encodings via their encoding string,
ensuring types are fetched from the target only once, if at all (may
already have the type due to it being common).
Things were getting rather cluttered with everything being qwaq-* and
all in one directory. Now most have lost the qwaq- prefix and have been
moved into subdirectories (non-recursive make).
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.
