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.
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 - -
b46e009d 16# pvop/svop - " cop - ; methop - .
2f7c6295 17# unop_aux - +
