* 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.
* tests/dynamic-scope.test, tests/eval.test,
tests/r5rs_pitfall.test, tests/srfi-17.test, tests/syncase.test:
Wrap tests in module (test-suite test-<file-name without .test>),
following a practice that was used on a couple of files already.
* tests/dynamic-scope.test (exception:duplicate-binding,
exception:bad-binding): New.
* tests/dynamic-scope.test, tests/srfi-17.test, tests/syntax.test:
Execute syntactically wrong tests using eval. With the upcoming
new memoizer this is necessary in order to postpone the syntax
check to the actual evaluation of the syntactically wrong form.
* tests/syntax.test: Added some test cases and modified one test
case.
(main data-file-name test-file-name): Exported.
((guile-user)::main): New function, wrapper for function
(test-suite guile-test)::main.
* tests/load.test: Wrapped in module (test-suite test-load).
* tests/ports.test: Wrapped in module (test-suite test-ports).
* tests/r4rs.test: Wrapped in module (test-suite test-r4rs).
Added comments about the required structure of the file itself,
since it is subject to some tests. Removed some now unnecessary
undefine operations.
* tests/syntax.test: Wrapped in module (test-suite test-syntax)
should only be used in cases, where guile has a known bug. It
should not be used in cases where an expression is expected to
return #f as its correct result.
