/* This program reads the machine description for the compiler target machine
and produces a file containing these things:
- 1. An array of `struct insn_data', which is indexed by insn code number,
+ 1. An array of `struct insn_data_d', which is indexed by insn code number,
which contains:
a. `name' is the name for that pattern. Nameless patterns are
MATCH_OPERAND; it is zero for operands that should not be changed during
register elimination such as MATCH_OPERATORs.
+ g. `allows_mem', is true for operands that accept MEM rtxes.
+
The code number of an insn is simply its position in the machine
description; code numbers are assigned sequentially to entries in
the description, starting with code number 0.
