Estimated hours taken: 2 Branches: main compiler/*.m: Import only one compiler module per line. Sort the blocks of imports. This makes it easier to merge in changes. In a couple of places, remove unnecessary imports.

:- module backend_libs__code_model.
|
|
|
|
% This module defines the `code_model' data type, and associated procedures.
|
|
% The `code_model' type is a simplified version of the `determinism' type
|
|
% that is defined in prog_data.m. It ignores most of the distinctions in
|
|
% the determinism type and keeps only the distinctions that are important
|
|
% for code generation.
|
|
|
|
% We define this in a different module than the `determinism' type because
|
|
% it is only used by some of the different back-ends, not all of them.
|
|
% It is used by the MLDS, LLDS, and bytecode back-ends, but not by the
|
|
% Aditi-RL back-end.
