1 # New ops always go at the end
2 # The restriction on having custom as the last op has been removed
4 # A recapitulation of the format of this file:
5 # The file consists of five columns: the name of the op, an English
6 # description, the name of the "check" routine used to optimize this
7 # operation, some flags, and a description of the operands.
9 # The flags consist of options followed by a mandatory op class signifier
12 # baseop - 0 unop - 1 binop - 2
13 # logop - | listop - @ pmop - /
14 # padop/svop - $ padop - # (unused) loop - {
15 # baseop/unop - % loopexop - } filestatop - -
16 # pvop/svop - " cop - ; methop - .
20 # needs stack mark - m (OA_MARK)
21 # needs constant folding - f (OA_FOLDCONST)
22 # produces a scalar - s (OA_RETSCALAR)
23 # produces an integer - i (unused)
24 # needs a target - t (OA_TARGET)
25 # target can be in a pad - T (OA_TARGET|OA_TARGLEX)
26 # has a corresponding integer version - I (OA_OTHERINT)
27 # make temp copy in list assignment - d (OA_DANGEROUS)
28 # uses $_ if no argument given - u (OA_DEFGV)
30 # Values for the operands are:
31 # scalar - S list - L array - A
32 # hash - H sub (CV) - C file - F
33 # socket - Fs filetest - F- filetest_access - F-+
34 # num-compare - S< dirhandle - DF
37 # "?" denotes an optional operand.
