When the substring is the tail of the supplied string, return a
"pointer" to within the supplied string rather than a new "return"
string. This means that tail-end substrings of string constants are
themselves constants.
The engine now requires non-v6 progs to store the log2 alignment for the
param struct in .param_alignment.
PR_EnterFunction is clearer and possibly more efficient.
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.
This makes sure that some unchecked event doesn't cause a lockup.
However, blocking input is really not the way to go: need to implement a
state machine and use non-blocking event reads.
Or really, allow it if the user specifically requests it: the default is
blocked. Modern systems (particularly displays) do not really like
changing resolution, so doing so by default seems rather wrong.
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).
I've decided that setting pr.max_edicts and pr.zone_size as part of the
local progs initialization rather than in PR_LoadProgsFile makes more
sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.
I'm not certain despair actually meant for the break to be there. It
certainly would have sped up the game a bit but at the expense of proper
blood trails in the software renderers.
These are the ones where I could easily make scan-build happy. They do seem
to be potential holes where invalid data in one place could result in use
of uninitialized values.
While scan-build wasn't what I was looking for, it has proven useful
anyway: many of the sizeof errors were just noise, but a few were actual
bugs (allocating too much or too little memory).
This was caused by an out-by one error when setting up the skin: if cmap
was 0 then the gl_skin struct would be taken from index -1 of the array and
thus cause all sorts of grief.
