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