New static identifiers.
(s_clauses, s_formals, s_duplicate_formals): Removed.
(scm_m_lambda): Use ASSERT_SYNTAX to signal syntax errors. Be more
specific about the kind of error that was detected. Prepare for
easier integration of changes for separated memoization.
* test-suite/tests/syntax.test (define exception:bad-formal, define
exception:duplicate-formal): New.
(exception:duplicate-formals): Removed.
(exception:bad-formals): Adapted to the new way of error
reporting.
Adapted tests for 'lambda' to the new way of error reporting.

(scm_m_define): Added comment about how we check for duplicate
formals.
(scm_m_do): Added check for duplicate bindings.
(scm_m_if): Use ASSERT_SYNTAX to signal syntax errors. Avoid
unnecessary consing when creating the memoized code.
(scm_c_improper_memq, c_improper_memq, scm_m_lambda): Renamed
scm_c_improper_memq to c_improper_memq, since it is not exported.
(transform_bindings): Call scm_c_memq rather than
scm_c_improper_memq.
(SCM_CEVAL): Simplified handling of SCM_IM_IF forms.
* test-suite/tests/syntax.test (exception:missing/extra-expr-syntax):
New, introduced temporarily until all memoizers use the new way of
error reporting.
Adapted tests for 'if' to the new way of error reporting.
static identifiers.
(scm_m_do): Use ASSERT_SYNTAX to signal syntax errors. Be more
specific about the kind of error that was detected. Avoid use of
SCM_CDRLOC. Avoid unnecessary consing when creating the memoized
code, this way also making sure that file name, line number
information etc. remain available.
identifiers.
(scm_m_define): Use ASSERT_SYNTAX to signal syntax errors. Prefer
R5RS terminology for the naming of variables. Be more specific
about the kind of error that was detected. Make sure file name,
line number etc. are added to all freshly created expressions.
Avoid unnecessary consing when creating the memoized code.
* test-suite/tests/syntax.test (exception:missing-expr,
exception:extra-expr): New.
Adapted tests for 'begin' to the new way of error
reporting.
s_bad_cond_clause, s_missing_recipient): New static identifiers.
(s_extra_case_clause): Removed.
(scm_m_case, scm_m_cond): If a clause appears after an else
clause, report a misplaced else clause.
(scm_m_cond): Use ASSERT_SYNTAX to signal syntax errors. Be more
specific about the kind of error that was detected. Handle bound
'else and '=>. Avoid unnecessary consing when creating the
memoized code.
(scm_m_cond, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
the syntactic keyword 'else and SCM_IM_ARROW to memoize the
syntactic keyword '=>.
* test-suite/tests/syntax.test (exception:misplaced-else-clause,
exception:bad-cond-clause): New.
(exception:bad/missing-clauses, exception:extra-case-clause):
Removed.
Adapted tests for 'case' and 'cond' to the new way of error
reporting.
The tests that check if cond is hygienic pass now.
* libguile/print.c (scm_isymnames): Add names for the new memoizer
codes.
* libguile/eval.c (s_missing_clauses, s_bad_case_clause,
s_extra_case_clause, s_bad_case_labels, s_duplicate_case_label,
literal_p): New static identifiers.
(scm_m_case): Use ASSERT_SYNTAX to signal syntax errors. Be more
specific about the kind of error that was detected. Check for
duplicate case labels. Handle bound 'else. Avoid unnecessary
consing when creating the memoized code.
(scm_m_case, unmemocopy, SCM_CEVAL): Use SCM_IM_ELSE to memoize
the syntactic keyword 'else.
* test-suite/tests/syntax.test (exception:bad-expression,
exception:missing-clauses, exception:bad-case-clause,
exception:extra-case-clause, exception:bad-case-labels): New.
Added some tests and adapted tests for 'case' to the new way of
error reporting.
ASSERT_SYNTAX, ASSERT_SYNTAX_2): New static identifiers.
(scm_m_and): Use ASSERT_SYNTAX to signal syntax errors. Avoid
unnecessary consing when creating the memoized code.
* test-suite/lib.scm (run-test-exception): Handle syntax errors.
implementation of evaluator specific memoization codes and special
constants like #f, '() etc. ('flags'), which are not evaluator
specific. The goal is to remove definitions of evaluator
memoization codes completely from the public interface. This will
make it possible to experiment more freely with optimizations of
guile's internal representation of memoized code.
* objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
* print.c (iflagnames): New array, holding the printed names of
guile's special constants ('flags').
(scm_isymnames): Now holds only the printed names of the
memoization codes.
(scm_iprin1): Separate the handling of memoization codes and
guile's special constants.
* tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
SCM_IFLAGNUM): new
(scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
values.
(SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
tc9 macros and scm_tc9_flag.
The typecode of the former 14th short instruction is now used to
represent long instructions. Changed some comments to reflect
this fact.
(SCM_MAKISYM): ISYMs get a new tc7 code, namely the one that was
previously used by SCM_IM_DEFINE.
(SCM_IM_DEFINE): Turned into a long instruction.
* eval.c (unmemocopy, SCM_CEVAL): Treat SCM_IM_DEFINE as a long
instruction.
* eval.c (SCM_CEVAL): Since characters and iflags have now a tc7
code that is separate from all instructions, one level of dispatch
for long instructions can be eliminated.
* print.c (scm_isymnames): Removed some commented code.
of SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
* numbers.h, deprecated.h (SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP,
SCM_SLOPPY_COMPLEXP): Deprecated and moved from numbers.h to
deprecated.h.
SCM_SLOPPY_INEXACTP, SCM_SLOPPY_REALP and SCM_SLOPPY_COMPLEXP.
* eq.c (scm_eqv_p, scm_equal_p): Reordered comparisons from
0.0==some_expression to some_expression==0.0. The latter is
better readable. The former is preferred by some people, since it
leads to a compiler error when confusing == with =. However, when
using gcc, a warning will be issued if in an if-statement an
assigment appears. Since many Guile developers are using gcc,
such errors will not remain unnoticed anyway. We can therefore
focus on better readability.
