# 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)

#	Suspicious wrt "additional mode of failure": warn, die, select.

# New ops always go at the end, just before 'custom'

# A recapitulation of the format of this file:
# The file consists of five columns: the name of the op, an English
# description, the name of the "check" routine used to optimize this
# operation, some flags, and a description of the operands.

# The flags consist of options followed by a mandatory op class signifier

# The classes are:
# baseop      - 0            unop     - 1            binop      - 2
# logop       - |            listop   - @            pmop       - /
# padop/svop  - $            padop    - # (unused)   loop       - {
# baseop/unop - %            loopexop - }            filestatop - -
# pvop/svop   - "            cop      - ;

# Other options are:
#   needs stack mark                    - m
#   needs constant folding              - f
#   produces a scalar                   - s
#   produces an integer                 - i
#   needs a target                      - t
#   target can be in a pad              - T
#   has a corresponding integer version - I
#   has side effects                    - d
#   uses $_ if no argument given        - u

# Values for the operands are:
# scalar      - S            list     - L            array     - A
# hash        - H            sub (CV) - C            file      - F
# socket      - Fs           filetest - F-           reference - R
# "?" denotes an optional operand.
