1 | # New ops always go at the end |
2 | # The restriction on having custom as the last op has been removed | |
3 | ||
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. | |
8 | ||
9 | # The flags consist of options followed by a mandatory op class signifier | |
10 | ||
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 - ; | |
17 | ||
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 | |
28 | ||
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-+ | |
33 | ||
34 | # reference - R | |
35 | # "?" denotes an optional operand. | |
