... and bundle sets of error kinds and their associated lists of error_specs
into a single structure.
compiler/parse_error.m:
Use separate types to represent fatal errors and nonfatal errors,
because those two kinds of errors are often treated differently.
Change the read_module_errors type, which used to be just a set of errors,
to being a set of fatal errors, a set of nonfatal errors, the error
message for each, and error messages for warnings. This preserves
distinctions that we should be able to use in the future to improve
error handling.
Provide utility routines for operating on this now-structured type.
compiler/parse_types.m:
Change the definition of the item_or_marker type slighly to preserve
distinctions that the read_module_errors type now cares about.
compiler/parse_module.m:
Thread the new read_module_errors structure through the predicates
that parse source, interface and optimization files.
Treat the failure of reading the contents of a file as a fatal error.
Previously, we treated it as a nonfatal error.
Delete some fields from types when those field were always set to the
same value, and therefore contained no useful information.
compiler/module_baggage.m:
Switch to using the new read_module_errors structure in module baggage.
compiler/grab_modules.m:
Conform to the changes above.
Use a bespoke type to represent the absence/presence of errors
when reading in optimization files.
compiler/mercury_compile_make_hlds.m:
Conform to the changes above.
Delete a call to pre_hlds_write_out_errors that duplicates
another call a few lines above.
compiler/deps_map.m:
compiler/generate_dep_d_files.m:
compiler/make.module_dep_file.m:
compiler/mercury_compile_main.m:
compiler/parse_item.m:
compiler/parse_pragma.m:
compiler/parse_type_defn.m:
compiler/read_modules.m:
compiler/recompilation.check.m:
compiler/write_deps_file.m:
compiler/write_module_interface_files.m:
Conform to the changes above.

% File: write_module_interface_files.m.
|
|
% Main author: fjh (when this code was in modules.m).
|
|
%
|
|
% This module writes the automatically generated .int3, .int2 and .int files
|
|
% (and if needed, the .int0 file) for each Mercury source module.
|
|
%
|
|
% The interface file system works as follows:
|
|
%
|
|
% 1. a .int3 file is written, which contains all the types, typeclasses, insts
|
|
% and modes defined in the interface. Equivalence types, solver types, insts
|
|
% and modes are written in full, others are written in abstract form. These
|
|
% are module qualified as far as possible given the information present in the
|
|
% current module.
|
|
%
|
|
% 2. The .int and .int2 files are created, using the .int3 files
|
|
% of imported modules to fully module qualify all items.
|
|
% The .int2 file is mostly just a fully qualified version of the .int3 file,
|
|
% however it also includes some extra information, such as functors for
|
|
% discriminated union types, which may be needed for mode analysis.
|
|
%
|
|
% 3. The .int0 file is similar to the .int file except that it also
|
|
% includes declarations (but not clauses) from the implementation section.
|
|
% It is generated only for modules that have submodules.
|
|
%
|
|
% NOTE The above is only a summary, and may be out of date. An attempt
|
|
% at an up-to-date and much more detailed description can be found in
|
|
% notes/interface_files.html.
