mercury/compiler/layout_out.m
Zoltan Somogyi cc9912faa8 Don't import anything in packages. 
Packages are modules whose only job is to serve as a container for submodules.
Modules like top_level.m, hlds.m, parse_tree.m and ll_backend.m are packages
in this (informal) sense.

Besides the include_module declarations for their submodules, most of the
packages in the compiler used to import some modules, mostly other packages
whose component modules their submodules may need. For example, ll_backend.m
used to import parse_tree.m. This meant that modules in the ll_backend package
did not have to import parse_tree.m before importing modules in the parse_tree
package.

However, this had a price. When we add a new module to the parse_tree package,
parse_tree.int would change, and this would require the recompilation of ALL
the modules in the ll_backend package, even the ones that did NOT import ANY
of the modules in the parse_tree package.

This happened even at one remove. Pretty much all modules in every one
of the backend have to import one or more modules in the hlds package,
and they therefore have import hlds.m. Since hlds.m imported transform_hlds.m,
any addition of a new middle pass to the transform_hlds package required
the recompilation of all backend modules, even in the usual case of the two
having nothing to do with each other.

This diff removes all import_module declarations from the packages,
and replaces them with import_module declarations in the modules that need
them. This includes only a SUBSET of their child modules and of the non-child
modules that import them.

% at least handle the previous version of the data structure,
% it makes it easier to bootstrap changes to these data structures.
%
% This number should be kept in sync with MR_LAYOUT_VERSION in

% layout structures to conform to whatever changes the new version

% Print out vectors of numbers.

% We print ten numbers per line to make it easy to locate a particular element
% in a vector.
%
% We do a two level loop to limit the number of stack frames we consume
% in grades that do not permit tail recursion. The idea is that after printing
% 1000 numbers, we free up all the stack space that printing consumed.
% When printing N numbers, we use only about (N / 1000) + (N mod 1000) frames.

% Each predicate has two versions. The _ac version assumes auto-comment,
% the _noac version assumes no auto-comment.
