because breakpoints are now implemented outside the core distro.
Add entries on obsolescence of the 'cheap option and on tweaking
support in evaluator trap calls. Finally, correct outline level
of item about make-keyword-from-dash-symbol.
* gc-segment.c (scm_i_all_segments_statistics): new function.
(scm_i_heap_segment_statistics): new function
* gc.c (s_scm_gc_live_object_stats): new GUILE callable: return
statistics on the number of live objects of each type.
* gc-card.c (scm_i_tag_name): new function.
(scm_i_card_statistics): new function.
scm_i_unmemoize_expr for unmemoizing a memoized object holding a
single memoized expression.
* debug.c (memoized_print): Don't try to unmemoize the memoized
object, since we can't know whether it holds a single expression
or a body.
(scm_mem_to_proc): Removed check for lambda expression, since it
was moot anyway. Whoever uses these functions for debugging
purposes should know what they do: Creating invalid memoized code
will cause crashes, independent of whether this check is present
or not.
(scm_proc_to_mem): Take the closure's code as it is and don't
append a SCM_IM_LAMBDA isym. To allow easier debugging, the
memoized code should not be modified.
* debug.[ch] (scm_unmemoize, scm_i_unmemoize_expr): Removed
scm_unmemoize from public use, but made scm_i_unmemoize_expr
available as a guile internal function instead. However,
scm_i_unmemoize_expr will only work on memoized objects that hold
a single memoized expression. It won't work with bodies.
* debug.c (scm_procedure_source), macros.c (macro_print), print.c
(scm_iprin1): Call scm_i_unmemocopy_body for unmemoizing a body,
i. e. a list of expressions.
* eval.c (unmemoize_exprs): Drop internal body markers from the
output during unmemoization.
* eval.[ch] (scm_unmemocopy, scm_i_unmemocopy_expr,
scm_i_unmemocopy_body): Removed scm_unmemocopy from public use,
but made scm_i_unmemocopy_expr and scm_i_unmemocopy_body available
as guile internal functions instead. scm_i_unmemoize_expr will
only work on a single memoized expression, while
scm_i_unmemocopy_body will only work on bodies.
copy lists that are known to be finite (though not necessarily
proper).
* debug.c (scm_procedure_source): Don't have scm_unmemocopy treat
a closure's argument list like an expression of a body.
* eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and,
unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay,
unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let,
unmemoize_letrec, unmemoize_letstar, unmemoize_or,
unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc,
unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref,
unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x,
unmemoize_builtin_macro): New static functions and symbols.
(scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy
now has a slightly different meaning: The memoized form that is
receives as its argument is now interpreted as a sequence of
expressions from a body.
(unmemocar, scm_unmemocar): Since the whole functionality of
unmemocar and scm_unmemocar is not needed any more, scm_unmemocar
has its old content back and is deprecated, while unmemocar has
been removed.
(SCM_BIT7): Removed.
(CEVAL): For unmemoizing a single expression, call
unmemoize_expression instead of scm_unmemocopy, which now expects
a sequence of body expressions. Eliminated unnecessary empty
environment frame when executing let* forms. Eliminated
unmemoization step from evaluator.
