(scm_m_quote, scm_m_atslot_ref, SCM_CEVAL): Changed the byte code
representation of 'quote' and '@slot-ref' to an improper list.
This reduces execution time, the number of cells used to hold the
memoized code, and thus also reduces garbage collection time.
(scm_unmemocopy): Use unmemoize_quote for quote expressions.
(SCM_CEVAL): Changed macro handling to also work with macros that
return improper lists. Added an assertion, that the code returned
by a macro transformer will not lead to cycles in the memoized
code.
file.
* eval.c (scm_ilookup, scm_unbound_variable_key,
error_unbound_variable, scm_lookupcar1, scm_lookupcar): Moved to
the definitions used for execution, since that's where they will
belong to later.
throughout guile, has not been part of an official release yet,
and the concept of sloppy predicates has never been a good idea.
(SCM_FRACTION_NUMERATOR, SCM_FRACTION_DENOMINATOR,
SCM_FRACTION_SET_NUMERATOR, SCM_FRACTION_SET_DENOMINATOR):
Simplified.
explicit what happens.
* guardians.c (TCONC_IN): Use SCM_SET_CELL_OBJECT_x rather than
SCM_SET_CELL_WORD_x when writing scheme objets to cell elements.
scm_round_number): New functions, replacing scm_tc7_cxr definitions,
and ensuring exact arguments give exact results, as required by R5RS.
Derived in part from the same by Marius in the cvs head. Reported by
Ray Lehtiniemi.
(fx): Removed.
(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
number_chars): New, to support variable radices.
(idbl2str): Use above instead of the old base-10 only tables.
(iflo2str): Pass on new RADIX argument to idbl2str.
(scm_number_to_string): Pass radix to iflo2str.
(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
iflo2str.
(scm_init_numbers): Call init_dblprec and init_fx_radix for all
possible radices.
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".
