510# Some comments about 'T' opcode classifier:
511
512# Safe to set if the ppcode uses:
513# tryAMAGICbin, tryAMAGICun, SETn, SETi, SETu, PUSHn, PUSHTARG, SETTARG,
514# SETs(TARG), XPUSHn, XPUSHu,
515
516# Unsafe to set if the ppcode uses dTARG or [X]RETPUSH[YES|NO|UNDEF]
517
518# lt and friends do SETs (including ncmp, but not scmp)
519
21f5b33c 520# Additional mode of failure: the opcode can modify TARG before it "used"
521# all the arguments (or may call an external function which does the same).
522# If the target coincides with one of the arguments ==> kaboom.
523
b162f9ea 524# pp.c pos substr each not OK (RETPUSHUNDEF)
525# substr vec also not OK due to LV to target (are they???)
526# ref not OK (RETPUSHNO)
527# trans not OK (dTARG; TARG = sv_newmortal();)
528# ucfirst etc not OK: TMP arg processed inplace
69b47968 529# quotemeta not OK (unsafe when TARG == arg)
91e74348 530# each repeat not OK too due to list context
b162f9ea 531# pack split - unknown whether they are safe
dae78bb1 532# sprintf: is calling do_sprintf(TARG,...) which can act on TARG
533# before other args are processed.

21f5b33c 535# Suspicious wrt "additional mode of failure" (and only it):
536# schop, chop, postinc/dec, bit_and etc, negate, complement.
537

572# The file consists of five columns: the name of the op, an English
573# description, the name of the "check" routine used to optimize this
574# operation, some flags, and a description of the operands.
575
576# The flags consist of options followed by a mandatory op class signifier
577
578# The classes are:
579# baseop - 0 unop - 1 binop - 2
580# logop - | listop - @ pmop - /
581# padop/svop - $ padop - # (unused) loop - {
582# baseop/unop - % loopexop - } filestatop - -
3508218b 583# pvop/svop - " cop - ;
64b99527 584
585# Other options are:
586# needs stack mark - m
587# needs constant folding - f
588# produces a scalar - s
589# produces an integer - i
590# needs a target - t
591# target can be in a pad - T
592# has a corresponding integer version - I
593# has side effects - d
594# uses $_ if no argument given - u
595
596# Values for the operands are:
597# scalar - S list - L array - A
598# hash - H sub (CV) - C file - F
6ecf81d6 599# socket - Fs filetest - F- filetest_access - F-+
