Abdulaziz Ghuloum fc80aaae37 - added the ability to inject arbitrary compile time values using:
(define-syntax foo (make-compile-time-value <expr>))
  The value can be retrieved using curried macro transformers.
  E.g.,
     (let-syntax ([idval
                   (lambda (x)
                     (syntax-case x ()
                       [(_ id)
                        (lambda (rho)
                          (with-syntax ([val (datum->syntax #'here (rho #'id))])
                            #''val))]))])
       (let-syntax ([ctval (make-compile-time-value 'foo)])
         (list (idval ctval) (idval others))))
     ;=> (foo #f)

Abdulaziz Ghuloum 89d9a472a5 "darwin" is no longer hardcoded in lib/ypsilon-compat.ikarus.ss,
instead, it is obtained from the target info that autoconf
generates.
2008-09-24 23:18:35 -04:00
Abdulaziz Ghuloum 06fd988a17 C callbacks now reach the C point where they should make the call

Abdulaziz Ghuloum 8e750562d6 - Added memory operations on pointer types for setting and accessing
char, short, int, and long values from pointer arrays.
2008-09-13 07:49:17 -07:00
Abdulaziz Ghuloum e05e84d1c2 Added dlopen, dlclose, dlerror, dlsym, malloc, and free to

Abdulaziz Ghuloum fcef21c693 - Added (environment-symbols <env>) which returns a list of symbols
exported by the environment.  Try 
  > (environment-symbols (environment '(rnrs)))

- 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.
2008-07-24 18:58:53 -07:00
Abdulaziz Ghuloum 01c4afa320 Major work towards the AMD64 port. Most important of which is that
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.
2008-07-18 01:35:13 -07:00
Abdulaziz Ghuloum c3b12a22e8 the repl now resets on receiving &interrupted conditions. 2008-07-12 20:05:45 -07:00
Abdulaziz Ghuloum eccca7f4ea - Added trace-let-syntax, trace-letrec-syntax, as well as fixed
trace-define-syntax to handle variable transformers.

- added primops for fx comparison functions.
2008-07-11 22:31:40 -07:00
Abdulaziz Ghuloum 579b823f44 WIP on tag analysis, annotations, and utilization. 2008-07-06 23:48:16 -07:00
Abdulaziz Ghuloum d73dfd1287 - More work on the new optimizer
- 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.
2008-06-29 12:35:34 -07:00
Abdulaziz Ghuloum 66464cc348 Fixed a bug when doing (/ 1 1 1 ...). 2008-06-28 13:02:05 -07:00
Abdulaziz Ghuloum 45346ef865 - Added cp0! including:
- (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.
2008-06-28 02:25:44 -07:00
Abdulaziz Ghuloum 7d9ed176ac More work on cp0 which can now swallow the compiler but cannot yet
fold any primitives.
2008-06-22 22:10:05 -07:00
Abdulaziz Ghuloum 8f0f0abbca Applied a patch supplied by Derick Eddington that provides enhanced
functionality for waitpid (nonblocking waitpid and more status info)
as well as the ability to send a signal to a process, e.g., 
  (kill pid 'HUP).

Abdulaziz Ghuloum a492d318e1 - fixed minor bug in current-directory
- changed implementation of string->number.
2008-05-31 20:10:17 -07:00
Abdulaziz Ghuloum 53905b9eea Changes from Derick Eddington supporting file system info:
- Added file-regular?, file-directory?, file-symbolic-link?,
  directory-list, make-directory, delete-directory, change-mode, 
  and make-symbolic-link.

- Bug fix in ikrt_open_input_fd and ikrt_open_output_fd which
  considered a 0 FD as an error.

- Bug fix in ikrt_getcwd about len+1.

- Bug fix of &i/o-file-protection which didn't have &i/o-filename as
  its parent.

- There is a new src/ikarus-errno.c file.  

- Made tcp-connect and friends tell when they "failed to resolve
  host name or connect".

- To support the uses of &i/o-filename subtypes, I modified
  print-condition so it will cleanly print the parents' fields of a
  condition;
