387# The file consists of five columns: the name of the op, an English
388# description, the name of the "check" routine used to optimize this
389# operation, some flags, and a description of the operands.
390
391# The flags consist of options followed by a mandatory op class signifier
392
393# The classes are:
394# baseop - 0 unop - 1 binop - 2
395# logop - | listop - @ pmop - /
396# padop/svop - $ padop - # (unused) loop - {
397# baseop/unop - % loopexop - } filestatop - -
398# pvop/svop - "
399
400# Other options are:
401# needs stack mark - m
402# needs constant folding - f
403# produces a scalar - s
404# produces an integer - i
405# needs a target - t
406# target can be in a pad - T
407# has a corresponding integer version - I
408# has side effects - d
409# uses $_ if no argument given - u
410

412# scalar - S list - L array - A
413# hash - H sub (CV) - C file - F
414# socket - Fs filetest - F- reference - R
