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
11# The classes are:
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 - ;
18# Other options are:
19# needs stack mark - m
20# needs constant folding - f
21# produces a scalar - s
22# produces an integer - i
23# needs a target - t
24# target can be in a pad - T
25# has a corresponding integer version - I
26# has side effects - d
27# uses $_ if no argument given - u
29# Values for the operands are:
30# scalar - S list - L array - A
31# hash - H sub (CV) - C file - F
32# socket - Fs filetest - F- filetest_access - F-+
34# reference - R
35# "?" denotes an optional operand.
37# Nothing.
