Branches: main
Merge the foreign_type pragma changes from the dotnet branch to the main
branch, plus do some more development work to generalise the change.
compiler/prog_data.m:
Add a type to hold the data from parsing a pragma foreign_type decl.
compiler/prog_io_pragma.m:
Parse the pragma foreign_type. This code is currently commented
out, while we decide on the syntax.
compiler/hlds_data.m:
Add a new alternative to hlds_type_body where the body of the type
is a foreign type.
compiler/make_hlds.m:
Place the foreign_type pragmas into the HLDS.
compiler/foreign.m:
Implement to_type_string which replaces export__type_to_type_string,
unlike export__type_to_type_string foreign__to_type_string takes an
argument specifying which language the representation is meant to be
in. to_type_string also needs to take a module_info to handle
foreign_types correctly. To avoid the need for the module_info to
be passed around the MLDS backend we provide a new type
exported_type which provides enough information for an alternate
version of to_type_string to be called.
compiler/export.m:
Delete export__type_to_type_string.
compiler/llds.m:
Since foreign__to_type_string needs a module_info, we add a new
field to pragma_c_arg_decl which is the result of calling
foreign__to_type_string. This avoids threading the module_info
around various llds passes.
compiler/mlds.m:
Record with in the mercury_type the exported_type, this avoids
passing the module_info around the MLDS backend.
Also add the foreign_type alternative to mlds__type.
Update mercury_type_to_mlds_type so that it handles types which are
foreign types.
compiler/mlds_to_il.m:
Convert a mlds__foreign_type into an ilds__type.
compiler/ilds.m:
The CLR spec requires that System.Object and System.String be
treated specially in the IL assembly so add them as simple types.
compiler/ilasm.m:
Before outputting a class name into the IL assembly check whether it
it can be simplified to a builtin type, and if so output that name
instead as required by the ECMA spec.
Changes for the addition of string and object as simple types.
doc/reference_manual.texi:
Document the new pragma, this is currently commented out because it
refers to syntax that has not yet been finalised.
compiler/fact_table.m:
compiler/llds_out.m:
compiler/ml_code_gen.m:
compiler/ml_code_util.m:
compiler/ml_simplify_switch.m:
compiler/ml_switch_gen.m:
compiler/ml_unify_gen.m:
compiler/mlds_to_c.m:
compiler/mlds_to_csharp.m:
compiler/mlds_to_gcc.m:
compiler/mlds_to_java.m:
compiler/mlds_to_mcpp.m:
compiler/pragma_c_gen.m:
compiler/rtti_to_mlds.m:
Changes to handle using foreign__to_type_string.
compiler/hlds_out.m:
compiler/intermod.m:
compiler/magic_util.m:
compiler/ml_type_gen.m:
compiler/recompilation_usage.m:
compiler/recompilation_version.m:
compiler/term_util.m:
compiler/type_ctor_info.m:
compiler/unify_proc.m:
Changes to handle the new hlds_type_body.
compiler/mercury_to_mercury.m:
Output the pragma foreign_type declaration.
compiler/module_qual.m:
Qualify the pragma foreign_type declarations.
compiler/modules.m:
Pragma foreign_type is allowed in the interface.
Reportedly Mercury does not work on Solaris 2.5.1 if it is compiled with
gcc 2.7.x. It should however work fine on Solaris 2.5.1 if you compile
it with gcc 2.8, or if you use gcc 2.7.x with an earlier version of Solaris.
The binary distribution for Solaris that we distribute was compiled
with gcc 2.7.2, so if you have Solaris 2.5.1, you may need to compile
Mercury yourself from our source distribution.
("Solaris 2.x" is also known as "SunOS 5.x".)
