Avoid a problem that was causing exception handlers to not work on MinGW /
Windows XP in the hlc grades.
configure.in:
scripts/mgnuc.in:
Avoid the use of gcc's -fomit-frame-pointer option on MinGW.
It interferes with the correct operation of setjmp / longjmp.
(It does *not* interfere with gcc's __builtin_{set,long}jmp, so
maybe exceptions should be implemented using those where possible.)
library/backjump.m:
Unrelated change: fix some broken debugging code.
Branches: main
Start a C# backend, adapted from mlds_to_java.m.
Some `pragma foreign_*' declarations are commented out in this change because
no bootstrap compiler will yet accept "C#" in the language specification.
The compiler already supported C# foreign_procs for the IL backend, but the IL
backend and this new backend do not agree on naming and calling conventions so
the changes to the existing C# foreign_procs will further break the IL backend.
Nobody cares.
Only tested so far with Mono on Linux.
compiler/mlds_to_cs.m:
New module. In the CVS Attic there exists an obsolete file named
mlds_to_csharp.m (replaced by mlds_to_managed.m) which we don't want to
conflict with.
For C# we need to know if a `pragma foreign_type' is a value or
reference type. Currently this is done by accepting a fake keyword
`valuetype' before the type name, like for IL.
compiler/ml_backend.m:
compiler/mercury_compile.m:
compiler/mercury_compile_mlds_back_end.m:
Hook up the C# backend.
compiler/globals.m:
Add `target_csharp' as a target language.
compiler/options.m:
Add `--csharp' and `--csharp-only' options and their synonyms.
compiler/handle_options.m:
Handle `target_csharp' like `target_java', except for features which
are still to be implemented.
compiler/add_pragma.m:
Allow C# as a `pragma foreign_export' language.
Allow C# for `pragma foreign_export_enum'.
Conform to changes.
compiler/hlds_data.m:
compiler/prog_data.m:
compiler/prog_io_pragma.m:
Accept C# as a language for `pragma foreign_type'.
Accept `csharp' as the name of a grade in trace parameters.
compiler/make_hlds_passes.m:
Reuse most of the code for implementing mutables on Java for C#.
compiler/mlds.m:
Add a new MLDS target language, `ml_target_csharp'.
Conform to changes.
compiler/ml_foreign_proc_gen.m:
Generate foreign_procs for C#.
compiler/foreign.m:
Update predicates to support C# targets.
compiler/c_util.m:
Make `quote_string' use hexadecimal escapes in C# string literals.
compiler/parse_tree.m:
compiler/java_names.m:
Add C# equivalents for predicates in this module. `java_names' is a
misleading module name, but the predicates for C# and Java share some
code and may possibly be combined in the future.
compiler/rtti.m:
Add predicates to return the names of RTTI structures in C#.
compiler/simplify.m:
Handle the trace parameter `grade(csharp)'.

library/builtin.m:
library/rtti_implementation.m:
library/type_desc.m:
Implement RTTI procedures for the new backend, which uses a high-level
data representation (like the Java backend). The existing C# code was
designed for the IL backend, which used a low-level representation of
the RTTI data structures.
Most (if not all) of the the "new" code is exactly the same as the Java
versions, with only syntactic changes.
Rename the C# class `void_0' to `Void_0' to match the naming convention
used by mlds_to_cs.m.
library/array.m:
Update the existing C# code to work with the new backend.
Use `object[]' as the type of all array of non-primitive types.
The problem is one we encountered on the Java backend: when creating a
new array based on the type of a single element, we don't know whether
the new array should contain elements of the class or superclass.
library/bool.m:
Export `bool' constants to C#.
library/exception.m:
Update the existing C# code to work with the new backend.
Move the `mercury.runtime.Exception' C# class to mercury_dotnet.cs.
library/float.m:
Add C# implementations of `is_nan' and `is_inf'.
library/list.m:
Add methods for manipulating lists from hand-written C# code.
library/string.m:
Add C# implementations of string procedures which were missing.
library/dir.m:
library/io.m:
library/library.m:
Update the existing C# code to work with the new backend.
library/private_builtin.m:
Update the existing C# code to work with the new backend.
Delete the static constants which are duplicated in mercury_dotnet.cs.
The mlds_to_cs.m will emit references to the constants in the latter
only.

Make these modules compile with the C# backend.
runtime/mercury_dotnet.cs.in:
Add RTTI classes to the `mercury.runtime' namespace, equivalent to
those on the Java backend.
Use enumerations `MR_TYPECTOR_REP_*' and `MR_SECTAG_*' constants so we
can switch on them.
Add the `UnreachableDefault' exception class.
Hide old classes which are unused with the new backend behind
#ifdef !MR_HIGHLEVEL_DATA.

Put all Mercury-generated Java classes into the package `jmercury' and
runtime classes into `jmercury.runtime'. The Mercury module hierarchy is
not reflected in the package name. We name sub-module classes using
their fully-qualified module names with `__' between components, e.g.
`bit_buffer.read' produces `class bit_buffer__read'.
As all generated Java code is in the same package we don't need to package
qualify identifiers, and we don't need the hack to avoid clashing package
and class names. It also makes it easier to write Java foreign code because
generated Java class names are easier to predict from Mercury module names.
The package names are not `mercury' and `mercury.runtime' because on
case-insensitive file systems we may end up with a `mercury' directory
that could be confused with the `Mercury' directory.
compiler/java_names.m:
Delete code related to mangling package names.
Remove the extra `mercury' prefix added to standard library module
names, as it is redundant with `jmercury'.
Change runtime package name.
compiler/mlds_to_java.m:
Make generated code follow the new packaging scheme.
Don't automatically import all runtime classes. It doesn't seem
necessary.
Update for new packaging scheme.

is called in a deep profiling grade. Support for backjumping in
the deep profiler is NYI.

Branches: main
Add support for thread-local backjumping in grades that support concurrency.
library/backjump.m:
Shift the C definition of backjump handlers and choice ids into the
runtime. This is needed because MR_Context now refers to them and
the runtime should not depend on the library.
Delete the XXX comment regarding pred_is_external/3. (This has been
fixed below.)
runtime/mercury_backjump.h:
runtime/mercury_backjump.c:
New module that defines those parts of the backjumping support that
the runtime requires access to.
In high-level C .par grades make the global state required by
backjumping thread-specific.
Conform to the usual coding conventions in the runtime in the new
versions of the data structures that were originally in backjump.m.
Rename ML_Choice_Id to MR_BackJumpChoiceId, the latter is less
ambiguous.
runtime/mercury_context.h:
runtime/mercury_context.c:
In low-level C grades add two extra fields to the MR_Context structure
to hold the global state required by backjumping.
In high-level C .par grades initialise the the thread-specific data that
is used to store the backjump global state at program startup.
Reformat a function prototype.
runtime/mercury_thread.h:
Reformat a function prototype.
runtime/Mmakefile:
Include the new files.

Add G12's backjump module to the standard library.
This will not be inlcuded in the library documentation or announced until
more of the XXXs have been dealt with.
I've included a diff between the G12 version of the backjump
module and this one below.
library/backump.m:
A module (from G12) that provides support for backjumping.
There are a number of minor modifications from the G12 version in
order to make this compile in .par and .profdeep grades but it is
otherwise unchanged.
library/library.m:
Include the new module.
doc/Mmakefile:
Do not include the backjump module in the library reference guide
for now.
tests/hard_coded/Mmakefile:
tests/hard_coded/backjump_test.{m,exp}:
Test backjumping (from the G12 nogood example.)
