scm_t_bits. Updated all users.
(SCM_GC_CARD_SIZE_MASK): Use SCM_GC_SIZEOF_CARD instead of
duplicating the code.
(SCM_CELL_OBJECT_LOC): New.
(SCM_CARLOC, SCM_CDRLOC): Use it instead of SCM_CELL_WORD_LOC.
(SCM_CELL_WORD_LOC): Moved to "deprecated.h".
code has support for. Fixes building with AIX cc, which is ansi but
doesn't define __STDC__. Reported by Keith Crane.
(var_start): Remove macro, this variation no longer required.
(scm_list_n): Use va_start directly.
Cast char to int for
ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
subscript. Reported by Andreas Vögele.
Also cast through unsigned char to avoid passing negatives to those
macros if input contains 8-bit values.
mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
subscript. Reported by Andreas Vögele.
Also cast through unsigned char to avoid passing negatives to those
macros if input contains 8-bit values.
(scm_m_define): Change order to first create binding and
evaluating the expression afterwards.
(scm_m_set_x): Memoize complete set! expression. Only leave
symbols if no binding exists at memoization time. Throw error if
assigning to a syntactic keyword.
(lazy_memoize_variable): New function.
(CEVAL): When execution set!, perform lazy memoization if
unmemoized symbol is detected.
* libguile/modules.c (module_variable): Return variables with
unbound value.
* libguile/tags.h: Fix comment.
* test-suite/tests/syntax.test: Add test case to check the correct
handling of define expressions.
scm_c_downcase): Use ctype.h toupper and tolower. This will be useful
in 8-bit locales, and ensures consistency with char-upper-case? and
char-lower-case? which already use ctype.h.
(scm_c_upcase_table, scm_c_downcase_table, scm_lowers, scm_uppers): Remove.
(scm_tables_prehistory): Remove.
expression a new variable in the local module is defined in terms
of an equally named variable from some other module, use @ to
refer to the variable in the other module. This is necessary due
to section 5.2.1 of R5RS: In a define expression first the new
binding is created and then the expression is evaluated.
* deprecated.h (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.c (SCM_IFRINC, SCM_ICDR, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP), eval.h (SCM_ICDR, SCM_IFRINC, SCM_IFRAME, SCM_IDIST,
SCM_ICDRP): Deprecated and added to deprecated.h. Moved from
eval.h to eval.c.
* deprecated.c (scm_isymnames), deprecated.h (scm_isymnames,
SCM_ISYMNUM, SCM_ISYMCHARS), eval.c (SCM_ISYMNUM, isymnames,
scm_unmemocopy, CEVAL), print.c (scm_isymnames), tags.h
(SCM_ISYMNUM, scm_isymnames, SCM_ISYMCHARS): Deprecated
scm_isymnames, SCM_ISYMNUM and SCM_ISYMCHARS and added to
deprecated.[hc]. Moved scm_isymnames from print.c to eval.c and
renamed to isymnames. Moved SCM_ISYMNUM from tags.h to eval.c and
renamed to ISYMNUM.
* eval.c (scm_i_print_iloc, scm_i_print_isym), eval.h
(scm_i_print_iloc, scm_i_print_isym), print.c (scm_iprin1):
Extracted printing of ilocs and isyms to guile internal functions
scm_i_print_iloc, scm_i_print_isym of eval.c.
