304 # Some comments about 'T' opcode classifier:
306 # Safe to set if the ppcode uses:
307 # tryAMAGICbin, tryAMAGICun, SETn, SETi, SETu, PUSHn, PUSHTARG, SETTARG,
308 # SETs(TARG), XPUSHn, XPUSHu,
310 # Unsafe to set if the ppcode uses dTARG or [X]RETPUSH[YES|NO|UNDEF]
312 # lt and friends do SETs (including ncmp, but not scmp)
314 # Additional mode of failure: the opcode can modify TARG before it "used"
315 # all the arguments (or may call an external function which does the same).
316 # If the target coincides with one of the arguments ==> kaboom.
318 # pp.c pos substr each not OK (RETPUSHUNDEF)
319 # substr vec also not OK due to LV to target (are they???)
320 # ref not OK (RETPUSHNO)
321 # trans not OK (dTARG; TARG = sv_newmortal();)
322 # ucfirst etc not OK: TMP arg processed inplace
323 # quotemeta not OK (unsafe when TARG == arg)
324 # each repeat not OK too due to list context
325 # pack split - unknown whether they are safe
326 # sprintf: is calling do_sprintf(TARG,...) which can act on TARG
327 # before other args are processed.
329 # Suspicious wrt "additional mode of failure" (and only it):
330 # schop, chop, postinc/dec, bit_and etc, negate, complement.
332 # Also suspicious: 4-arg substr, sprintf, uc/lc (POK_only), reverse, pack.
334 # substr/vec: doing TAINT_off()???
337 # readline - unknown whether it is safe
338 # match subst not OK (dTARG)
339 # grepwhile not OK (not always setting)
340 # join not OK (unsafe when TARG == arg)
342 # Suspicious wrt "additional mode of failure": concat (dealt with
343 # in ck_sassign()), join (same).
346 # mapwhile flip caller not OK (not always setting)
349 # backtick glob warn die not OK (not always setting)
350 # warn not OK (RETPUSHYES)
351 # open fileno getc sysread syswrite ioctl accept shutdown
