add qwe builtin extensions to qw-server. provide sv_progs_ext to control
the builtin mapping. valid values are "id", "qf" (our old static builtins),
"qwe"/"ktpro" (either works. for ktpro mod support) and "none" (no
mapping). any other value is equivalent to "none".
ranges can be used efficiently. move the auto-allocated builtins to
0x10000000-0x7fffffff. should be more than enough :)
use static builtin tables ("nul" terminated) instead of a series of
function calls to add builtins to a vm. should be more memory efficient.
and wrong anyway (could free strings it wasn't supposed to).
Don't free the string pointed to by a strref since it's already been
implicity freed (whole memory space nuked). Fixes new map crash.
o temporary strings automaticly get freed when the function they're
created in (results of str + str and most strings returned from
builtins). a way to keep temp strings will be provided later
o fix up qwaq to test the temp strings
handle SIGFPE and allow the registered signal handler to do recovery
rather than bail
progs.h, pr_exec.c, pr_load.c:
if pr_faultchecks is 1 (0 is default), handle division by 0 gracefully
by loading the maximum representable number into the answer
Closes: #58
the rest:
kill the SIGFPE stuff
methods directly or setup the progs struct for a normal function call to
call a progs method rather than recursively calling PR_ExecuteProgram. This
will reduce method call overhead (both cpu and stack usage), fix the loss
of tracing when calling a method and makes it possible to break out of the
progs engine simply if threaded progs are ever implemented.
o add ev_uniteger to the types enum
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
progs.h:
o add uinteger accessors
pr_exec.c:
o implement ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
pr_opcode.c:
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
expr.h:
o prototype inc_users
qfcc.h:
o add externs for op_ifbe, op_ifb, op_ifae and op_ifa
emit.c:
o don't bother emiting an assignment to a temp def that's only used once
(ie, it's never read, only written to)
o support the new if* instructions
expr.c:
o support the new if* insructions
o dectect expression loops in append_expr
o support unsigned integers
o re-work temp def usage counting
pr_def.c
o debugging for temp def usage counts
pr_opcode.c:
o support the new if* instructions
qc-parse.y:
o provide defines for IFBE IFB IFAE IFA
switch.c:
o do binary searches for strings, floats and ints if there are more than
8 cases in a switch. Strings need more testing.
