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

381 # A recapitulation of the format of this file:
382 # The file consists of five columns: the name of the op, an English
383 # description, the name of the "check" routine used to optimize this
384 # operation, some flags, and a description of the operands.
386 # The flags consist of options followed by a mandatory op class signifier
389 # baseop - 0 unop - 1 binop - 2
390 # logop - | listop - @ pmop - /
391 # padop/svop - $ padop - # (unused) loop - {
392 # baseop/unop - % loopexop - } filestatop - -
396 # needs stack mark - m
397 # needs constant folding - f
398 # produces a scalar - s
399 # produces an integer - i
401 # target can be in a pad - T
402 # has a corresponding integer version - I
403 # has side effects - d
404 # uses $_ if no argument given - u
406 # Values for the operands are:
407 # scalar - S list - L array - A
408 # hash - H sub (CV) - C file - F
409 # socket - Fs filetest - F- reference - R
410 # "?" denotes an optional operand.
