compiler/options.m:
doc/user_guide.texi:
Add a new developer-only option, --std-int-file-not-written-msgs,
which, if specified, calls for the "file not written" messages
we generate when we want to write interface files but can't
to be written out in a standard form that deletes the directory
path component from the names of the files not written out.
In the long term, it is less work to add this option once
than to add a separate .err_exp file for each affected test case.
compiler/write_module_interface_files.m:
Obey the new option.
tests/invalid/ee_invalid.m:
Add C# and Java foreign_types next to the C foreign_type.
tests/invalid/erroneous_throw_promise.m:
Add C# foreign_procs next to the C and Java foreign_procs.
tests/invalid/exist_foreign_error.m:
Add C# and Java foreign_procs next to a C foreign_proc.
tests/invalid/exist_foreign_error.err_exp:
tests/invalid/exist_foreign_error.err_exp2:
tests/invalid/exist_foreign_error.err_exp3:
Update the line number in the expected error output file for C,
and add expected error output files for Java and C#.
tests/invalid_make_int/bug17.{m,int_err_exp}:
tests/invalid_make_int/builtin_int.{m,int_err_exp}:
Move these test cases here from tests/invalid, since all the errors
we test for are reported when making the .int file.
tests/invalid/Mmakefile:
Delete the tests moved to tests/invalid_make_int.
tests/invalid_make_int/Mercury.options:
tests/invalid_make_int/Mmakefile:
Add the tests moved from tests/invalid. Specify the new option
for all the test cases.

% 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.
