toke.c: Add internal function to abort parsing

[perl5.git] / regen / opcodes

# New ops always go at the end
# The restriction on having custom as the last op has been removed

# 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      - ;            methop     - .
# unop_aux    - +

# Other options are:
#   needs stack mark                    - m  (OA_MARK)
#   needs constant folding              - f  (OA_FOLDCONST)
#   produces a scalar                   - s  (OA_RETSCALAR)
#   produces an integer                 - i  (unused)
#   needs a target                      - t  (OA_TARGET)
#   target can be in a pad              - T  (OA_TARGET|OA_TARGLEX)
#   has a corresponding integer version - I  (OA_OTHERINT)
#   make temp copy in list assignment   - d  (OA_DANGEROUS)
#   uses $_ if no argument given        - u  (OA_DEFGV)

# Values for the operands are:
# scalar      - S            list     - L            array     - A
# hash        - H            sub (CV) - C            file      - F
# socket      - Fs           filetest - F-           filetest_access - F-+
# num-compare - S<           dirhandle - DF          infix bitwise   - S|

# reference - R
# "?" denotes an optional operand.

# Nothing.
