| 525 | # Some comments about 'T' opcode classifier: |
| 526 | |
| 527 | # Safe to set if the ppcode uses: |
| 528 | # tryAMAGICbin, tryAMAGICun, SETn, SETi, SETu, PUSHn, PUSHTARG, SETTARG, |
| 529 | # SETs(TARG), XPUSHn, XPUSHu, |
| 530 | |
| 531 | # Unsafe to set if the ppcode uses dTARG or [X]RETPUSH[YES|NO|UNDEF] |
| 532 | |
| 533 | # lt and friends do SETs (including ncmp, but not scmp) |
| 534 | |
| 535 | # Additional mode of failure: the opcode can modify TARG before it "used" |
| 536 | # all the arguments (or may call an external function which does the same). |
| 537 | # If the target coincides with one of the arguments ==> kaboom. |
| 538 | |
| 539 | # pp.c pos substr each not OK (RETPUSHUNDEF) |
| 540 | # substr vec also not OK due to LV to target (are they???) |
| 541 | # ref not OK (RETPUSHNO) |
| 542 | # trans not OK (dTARG; TARG = sv_newmortal();) |
| 543 | # ucfirst etc not OK: TMP arg processed inplace |
| 544 | # quotemeta not OK (unsafe when TARG == arg) |
| 545 | # each repeat not OK too due to list context |
| 546 | # pack split - unknown whether they are safe |
| 547 | # sprintf: is calling do_sprintf(TARG,...) which can act on TARG |
| 548 | # before other args are processed. |
| 549 | |
| 550 | # Suspicious wrt "additional mode of failure" (and only it): |
| 551 | # schop, chop, postinc/dec, bit_and etc, negate, complement. |
| 552 | |
| 553 | # Also suspicious: 4-arg substr, sprintf, uc/lc (POK_only), reverse, pack. |
