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.
- new opcodes for pointers
progs.h:
- prototype PR_Check_Opcodes
pr_edict.c:
- move the static bounds checking to PR_Check_Opcodes in pr_opcode.c
pr_exec.c:
- vector instruction cleanup
- temporarily nuke bounds checking from storep.*
- move base of address results from pr->edicts to pr->pr_globals
- implement new pointer related instructions
- nuke proposed global pointer instructions (not flexible enough)
pr_opcode.c:
- add new pointer instuctions
- re-implement static bounds/invalid opcode checking. no more multiple
case statements to keep track of.
value
- switch some prints over NUM_FOR_BAD_EDICT
- change NUM_FOR_EDICT to call PR_RunError on error, instead of
PR_Error. That was it prints out a backtrace.
(I did it in reverse order ;)
generice, and also more in line with the rest of quake's clipping system
(ie, support the entity size selected hulls). I'm not /entirly happy with
what's here, but it's a start, and the force fields in customtf work /much/
better :)
add no_exec_limit field. Set to 1 to disable the runaway loop check
for unlimited runs (eg, in qwaq)
pr_exec.c:
don't bother checking the profile counter if pr->no_exec_limit is set
pr_strings.c:
free unreferenced dynamic strings rather than referenced.
add OP_ADD_S. WARNING!!! this /will/ move.
progs.h:
add prototype for PR_PrintStatement
pr_edict.c:
add OP_ADD_S support in the progs checker
pr_exec.c:
implement OP_ADD_S
tools/qfcc/include/.gitignore:
add config.h.in
qfcc.h:
nuke PR_NameImmediate and change PR_ParseImmediate's prototype (see
pr_imm.c)
pr_comp.c:
add ADD_S, adjust for PR_ParseImmediate's prototype, make
PR_ParseExpression work with non-sequential opcodes (slow, will work on
that next). Fix up initialised global parsing.
pr_imm.c:
nuke PR_NameImmediate. didn't work well and wasn't such a good idea anyway.
PR_ParseImmediate now accepts a def_t * arg. if null, will allocate a
new global def, otherwise it will initialize the def passed in.
qwaq/main.c:
sports some debugging code (dumps info about the progs it's running)
qwaq/main.qc:
better ADD_S testing
quakeio.h -> vfile.h
More diff reduction between trunk and my VFS code. Also took the time to
put some headers in order and fix a few #include's pointed out by moving
things around a bit.
