- refershed all boot files (because of added primitives)
- regenerated some autoconf files (to use newer version)
It returns syntax-object wrapped with the marks and substitutions
that have been added to new-id since its introduction as base-id.
The new-id and base-id should be free-identifier=? and new-id
should have the same (or more) marks as base-id.
- Ikarus fasl files and source files are not compared using
(< (file-mtime ikfasl) (file-mtime filename))
instead of
(<= (file-ctime ikfasl) (file-ctime filename))
unhandled causing compile time errors.
- fixed some bootstrapping issues with pointer? (which was moved out
of the (ikarus) library)
- freshened up the bootfiles for both 32- and 64-bit version of
ikarus.
(ikarus system $foreign).
- changed the names of some of the pointer primitives
- changed the name of the procedure make-ffi to make-callout
- updated examples and libraries to conform with new names
- updated the users guide to provide a complete description of
the (ikarus foreign) library
- updated list of missing R6RS features in the users guide

- Added an internal export mechanism so that identifiers can be
exported from within a library. The syntax is the same:
(export export-spec* ...)
when appears in a library's top level, adds the export specs to
the set of exported identifiers. So, one can do:
(library (A)
(export)
(import (ikarus))
(export a)
(define a 17))
When appearing in non-library definition context, the export form
is ignored.
indices (r6rs requirement).
- file-options are now represented as enum-sets (r6rs requirement)
- odd?, even?, lcm, remainder, etc., now accept inexact integers.
continuations work, more assembly instructions are testing in 64-bit
mode, and some arithmetic operations (shift-right, etc.) have been
fixed by removing some 32-bit dependencies.
- Deleted old optimizer and changed the meaning of optimize level to
be:
0: bypass the optimizer
1: copy propagation, constant folding, no inlining
1: copy propagation, constant folding, with inlining
The default is set to 1.
- (optimize-level [0,1,2]) and ikarus -O[0,1,2]
where -O0 = no optimizations
-O1 = using old optimizer
-O2 = using the new cp0 optimizer
defaults to -O1 for now.
- (cp0-size-limit n) which is the limit of the residual size for
each inlining attempt
- (cp0-effort-limit n) which is the limit on the effort expended
for each inlining attempt
- Rewrote the syntax-match macro to make use of the same technology
used in syntax-case itself resulting in reduced code size.
- Added (system-value <symbol>) which returns the system value.
E.g., (system-value 'car) => #<procedure car>
This is pretty much the same as
(eval <symbol> (environment '(ikarus)))
except that it does not involve compiling the expression or
consulting the library/expander systems.
- Fixed the fasl loader to make it understand complex numbers.
