Abdulaziz Ghuloum 09657334c0 fixed autoconf so that ffi.h and libffi are checked iff ffi is
enabled.  Also made prep-callback return #f if libffi does not
support closures.
2008-09-22 21:55:05 -04:00
Abdulaziz Ghuloum e07d8f9760 ffi callbacks sorta kinda work now. 2008-09-21 04:08:54 -04:00
Abdulaziz Ghuloum 06fd988a17 C callbacks now reach the C point where they should make the call
back into Scheme land.
2008-09-20 01:58:57 -04:00
Abdulaziz Ghuloum 31f5f88889 first test of ffi works:

    (dlsym (dlopen #f) "hello_world"))

Abdulaziz Ghuloum 30cd6a2de8 made environment-symbols work on the interaction-environment. 2008-09-10 11:02:42 -07:00
Abdulaziz Ghuloum 0b017898a8 - minor change to how export (with renaming) is parsed. When you
rename from-name to to-name, the from-name is now treated as an
  identifier while the to-name is treated as a symbol.
2008-09-10 08:17:18 -07:00
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.

parsing.

2008-07-18 22:21:57 -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 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 2c8cb7dda2 fixed a bug in matching library subversion in psyntax. 2008-06-28 03:16:21 -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.

Abdulaziz Ghuloum 4bb7e170b5 Some procedures (like console-output-port) did not get names when
printed (instead, they were just #<procedure>).  Names for
procedures that are defined like
  (define foo
    (let ([something ---]) 
      (lamdba () ---)))
now works.
2008-06-18 22:47:56 -07:00

  (kill pid 'HUP).

addressing for predicate operations.

Abdulaziz Ghuloum fe1f7077ff fixed minor bug in syntax-case where the wraps and marks of
top-marked wrapped syntax objects were incorrectly combined.
E.g., it used to be that:

  (syntax-case (datum->syntax #'foo #'(x y)) ()
    [(x y) 'shouldntmatch] [_ 'ok])

yields shouldntmatch; it's now ok.
2008-06-10 12:35:56 -07:00

Abdulaziz Ghuloum e7386cd7d7 Major changes to the interactive repl:
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
  top-level.

Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously.  In
  particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define.  Once
  something is defined at the top-level, a specific location for it
  is created, and all definitions, references, and set!s to that
  variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
  location for that variable.

Let's see how this goes.
