# Some comments about 'T' opcode classifier:
# Safe to set if the ppcode uses:
# tryAMAGICbin, tryAMAGICun, SETn, SETi, SETu, PUSHn, PUSHTARG, SETTARG,
# SETs(TARG), XPUSHn, XPUSHu,
# Unsafe to set if the ppcode uses dTARG or [X]RETPUSH[YES|NO|UNDEF]
# lt and friends do SETs (including ncmp, but not scmp)
# Additional mode of failure: the opcode can modify TARG before it "used"
# all the arguments (or may call an external function which does the same).
# If the target coincides with one of the arguments ==> kaboom.
# pp.c pos substr each not OK (RETPUSHUNDEF)
# substr vec also not OK due to LV to target (are they???)
# ref not OK (RETPUSHNO)
# trans not OK (dTARG; TARG = sv_newmortal();)
# ucfirst etc not OK: TMP arg processed inplace
# quotemeta not OK (unsafe when TARG == arg)
# each repeat not OK too due to list context
# pack split - unknown whether they are safe
# sprintf: is calling do_sprintf(TARG,...) which can act on TARG
# before other args are processed.
# Suspicious wrt "additional mode of failure" (and only it):
# schop, chop, postinc/dec, bit_and etc, negate, complement.
# Also suspicious: 4-arg substr, sprintf, uc/lc (POK_only), reverse, pack.
# substr/vec: doing TAINT_off()???
# pp_hot.c
# readline - unknown whether it is safe
# match subst not OK (dTARG)
# grepwhile not OK (not always setting)
# join not OK (unsafe when TARG == arg)
# Suspicious wrt "additional mode of failure": concat (dealt with
# in ck_sassign()), join (same).
# pp_ctl.c
# mapwhile flip caller not OK (not always setting)
# pp_sys.c
# backtick glob warn die not OK (not always setting)
# warn not OK (RETPUSHYES)
# open fileno getc sysread syswrite ioctl accept shutdown
# ftsize(etc) readlink telldir fork alarm getlogin not OK (RETPUSHUNDEF)
# umask select not OK (XPUSHs(&PL_sv_undef);)
# fileno getc sysread syswrite tell not OK (meth("FILENO" "GETC"))
# sselect shm* sem* msg* syscall - unknown whether they are safe
# gmtime not OK (list context)
