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.
rounding in x+0.5 when x is a big value already an integer. In
certain hardware rounding cases x+0.5 can give an adjacent integer,
leading to that as the result, when we really just wanted x itself.
scm_tc8_isym): Renamed scm_tags to scm_tc8_tags. Renamed
scm_tc9_flag to scm_tc8_flag. Introduced new identifier
scm_tc8_isym. Defined tc8-tags relative to scm_tc3_imm24.
Defined the tc8-tag for flags to be 0x04, which will mean that
SCM_BOOL_F will also have the value 0x04 instead of 0x013c. Due
to the reduced number of bits and the simpler bit pattern for
SCM_BOOL_F, certain machines may be able to use more efficient
processor instructions to deal with SCM_BOOL_F.
(SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA): Removed. These have
never been defined in a released version, thus no need to
deprecate them.
(SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Flags now use tc8
instead of tc9 tags.
(SCM_ISYMP, SCM_MAKISYM, SCM_ISYMNUM): Isyms now use tc8 instead
of tc9 tags.
(SCM_MAKSPCSYM): Removed. It is almost impossible that user code
could have used this definition.
(SCM_IM_AND, SCM_IM_BEGIN, SCM_IM_CASE, SCM_IM_COND, SCM_IM_DO,
SCM_IM_IF, SCM_IM_LAMBDA, SCM_IM_LET, SCM_IM_LETSTAR,
SCM_IM_LETREC, SCM_IM_OR, SCM_IM_QUOTE, SCM_IM_SET_X): Now encoded
as isyms, as special isyms don't exist any more.
before converting to unsigned int. This prevents hi-bit ascii as
being converted large integers.
(string_upcase_x): change caller for scm_{up,down}case to
scm_c_{up,down}case
* chars.h (scm_init_chars): change scm_{upcase,downcase} to
scm_c_{up,down}case.
(SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
