Zoltan Somogyi c0f4d93a3c Add a new grade component, .decldebug. It is as proposed on mercury-developers,
Estimated hours taken: 2
Branches: main

Add a new grade component, .decldebug. It is as proposed on mercury-developers,
minus the implications about I/O tabling. Those will come later.

compiler/options.m:
	Add a new option, --decl-debug, that switches on declarative debugging.

compiler/trace_params.m:
	The procedure that converts strings representing trace levels to trace
	levels themselves now has an extra argument, which gives the value of
	the --decl-debug option. If set, it raises the minimum trace level,
	and turn explicitly specifying trace levels `shallow' and `deep'
	into errors (since they are not sufficient for declarative debugging).

compiler/handle_options.m:
	Pass the value of the --decl-debug option to trace_params, and handle
	the errors that may result. Handle the implications of --decl-debug
	and the .decldebug grade component.

compiler/compile_target_code.m:
	Define MR_DECL_DEBUG when invoking the C compiler if --decl-debug is
	set.

runtime/mercury_conf_param.h:
	Document MR_DECL_DEBUG, which is defined iff the grade is a .decldebug
	grade.

runtime/mercury_grade.h:
	Take MR_DECL_DEBUG into account when computing the grade component
	related to debugging.

	Update the list of places that need to be modified when adding new
	grade components.

doc/user_guide.texi:
	Document --decl-debug and the .decldebug grade component.

	Document the events used by declarative debugging, since Mark didn't.

	Fix some minor unrelated omissions.

scripts/init_grade.sh-subr:
scripts/parse_grade_options.sh-subr:
scripts/final_grade.sh-subr:
scripts/canonical_grade.sh-subr:
scripts/mgnuc.in:
scripts/ml.in:
	Add a new shell variable, decl_debug, to represent the value of
	MR_DECL_DEBUG, and handle it as appropriate.

tests/debugger/Mmakefile:
	Do not execute shallow traced tests in .decldebug grades, since we
	don't support shallow tracing in such grades.

	Specify --trace decl instead of --trace deep in .decldebug grades
	when compiling the other tests, since we don't support --trace deep
	in .decldebug grades.
