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.
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.
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.
