Mmake.workspace: Mmakefile: configure.in: Handle the new ssdb directory. compiler/options.m: Add the --ssdb and --source-to-source-debug options. compiler/mercury_compile.m: Add the ssdb pass (it does nothing at the moment). compiler/modules.m: Implicitly import ssdb_builtin when compiling with --ssdb. mdbcomp/prim_data.m: Handle the ssdb module. ssdb/Mercury.options: ssdb/Mmakefile: ssdb/SSDB_FLAGS.in: ssdb/.mgnuc_copts: ssdb/.mgnuc_opts: ssdb/RESERVED_MACRO_NAMES: Build system for ssdb directory. ssdb/mer_ssdb.m: ssdb/ssdb.m: The operations which are needed by the source to source debugger. tools/bootcheck: Changes to the bootcheck script to handle the new ssdb module. browser/Mmakefile: bytecode/Mmakefile: library/Mmakefile: mdbcomp/Mmakefile: runtime/Mmakefile: trace/Mmakefile: Add the ALLOW_SSDB_PREFIX rules.
This directory holds the source code for the Mercury bytecode utilities. `mdis' is the Mercury bytecode disassembler. `mbi' is the Mercury bytecode interpreter. `libmbi' is the same thing, minus main(). All exported symbols defined in modules in this directory should be prefixed with `MB_', for "Mercury Bytecode", to avoid clashes with names defined in other packages.
