compiler/modules.m:
compiler/compile_target_code.m:
compiler/handle_options.m:
compiler/bytecode_data.m:
compiler/prog_io_util.m:
Bring these modules up to date with our current coding style. Use
predmode declarations and state variable syntax where appropriate.
Fix inconsistent indentation. Print more error messages using
error_util.m for printing error messages.
compiler/trace_param.m:
Add a new predicate for use by the updated code in handle_options.m.
compiler/error_util.m:
compiler/hlds_error_util.m:
Make error_util.m to be a submodule of parse_tree.m, not hlds.m.
Most of its predicates are not dependent on HLDS data structures.
Move the ones that are into a new module, hlds_error_util, that
is a submodule of hlds.m. Overall, this reduces the dependence
of submodules of parse_tree.m, including modules.m, on submodules
of hlds.m.
compiler/notes/compiler_design.html:
Update the documentation of compiler modes to account for
hlds_error_util.m.
compiler/hlds.m:
compiler/parse_tree.m:
Update the list of included submodules.
compiler/*.m:
Update module imports and module qualifications as needed for the
change above.
tests/invalid/*.{exp,exp2}:
Update the expected outputs of a bunch of test cases to reflect the new
format of some warning messages due to the user error_util; they now
observe line length limits, and print contexts in some cases where they
were previously missing.
