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