respect to recent changes in eval.c. Further, extracted test
cases for guile's extended set! functionality to srfi-17.test.
* tests/srfi-17.test: New file.
(scm_unmemocar): Use !SCM_CONSP instead of SCM_IMP.
Minimize scope of local variable. Eliminate dependency on
macro DEBUG_EXTENSIONS.
(s_splicing): New error message string.
(scm_m_body): Issue 'bad body' message rather than 'missing
expression' message.
(scm_m_quote): Eliminate unnecessary copying.
(scm_m_lambda, scm_m_letstar, scm_m_letrec, scm_m_let): Leave the
checking of the body to scm_m_body.
(scm_m_do): Move comment to function header. Rename arg1 to
binding. Made the code a bit easier to read.
(evalcar): Removed.
(iqq): Added a comment. Changed the depth parameter to
unsigned. Use size_t for vector lengths. Make sure vector object
is gc protected as long as its contents are read. Add some syntax
checks. Get rid of unnecessary SCM_IMP test. Clean up the
control structure a bit.
(scm_m_delay): Added comment about the implementation of
scm_m_delay.
(scm_m_define): Add comment about guile's currying define
syntax. Renamed 'proc' to 'name'. Eliminate dependency on macro
DEBUG_EXTENSIONS. Simplified code a bit. Eliminate SICP code.
(scm_m_letrec1): Removed. Part of the functionality is taken
over by the new function 'transform_bindings'.
(transform_bindings): New function. Takes over some of the
functionality of removed function 'scm_m_letrec1', namely to split
a list of bindings into a reversed list of variables and a list of
initializers.
(scm_m_letrec): Call 'transform_bindings'.
(scm_m_let): Minimized scope of local variables. Renamed 'proc'
to 'temp' and 'arg1' to 'binding'. Eliminated redundant SCM_NIMP
test. Use 'transform_bindings'. Fixed scoping error with named
let (Thanks to Aubrey Jaffer for reporting the bug and to Neil
Jerram for suggesting the fix). Cleaned up the control structure
a bit.
(scm_m_expand_body): Use 'transform_bindings'. Eliminated
unnecessary consing. Eliminated unnecessary
SCM_DEFER/ALLOW_INTS.
(SCM_CEVAL): Un-obfuscated some loops.
index entries for each Guile primitive to the copy of the doc
snarf output that is used for reference manual synchronization.
Online help is unchanged.
num2integral.i.c. MAX_VALUE and MIN_VALU are no longer used, we
now rely on SIZEOF_ macros that have been figured out at
configure time.
* num2integral.i.c: Adapt to new interface.
(NUM2INTEGRAL): Test whether a fixnum can be represented in the
target type by casting it and checking whether it is still the
same. Do not try to handle bignums for integral types that are
smaller than fixnums. When handling bignums, collect the
magnituse first into a unsigned type, and correctly check for
overflow.
(INTEGRAL2BIG): Do not use MIN_VALUE explicitely by observing that
only -MIN_VALUE can still be negative of all negative numbers (in
twos-complement).
