4909a9ef08
fixed make-rectangular so that (make-rectangular 1.0 0.0) returns
...
a cflonum 1.0+0.0i while (make-rectangular 1.0 0) returns 1.0.
2008-07-25 17:46:34 -07:00

kinda fixes a port-position computation bug for custom binary ports.
2008-07-24 22:30:21 -07:00

2008-07-24 00:06:12 -07:00
0305537374
get-u8 and lookahead-u8 did not update the port position properly.

...
assembler when addressing using special %eax/%rax instructions.
2008-07-21 22:07:31 -07:00
358eee03ee
Added a 64-bit bootfile and modified the configure script to not add
...
its own -m32 or -m64 flags. To built ikarus in 32-bit mode, one can
do:
./configure CFLAGS=-m32
and in 64-bit mode:
./configure CFLAGS=-m64
2008-07-20 14:09:04 -07:00
59b9d28001
guard expressions now re-raise unhandled conditions using
...
raise-continuable (as per the R6RS errata page, part 7.1)
2008-07-20 02:51:14 -07:00
78d9fa1f42
In 64-bit, ikarus now passes all tests, can recompile itself,
...
and runs all benchmarks (inefficiently but correctly).
2008-07-20 00:14:09 -07:00
4f48c55bfc
all existing tests pass under 64-bit
2008-07-19 14:41:06 -07:00
81a1a640df

...
64-bit bugs.
2008-07-18 22:21:57 -07:00
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
0ef81aa13e
Added make-polar.
2008-07-15 23:13:59 -07:00

2008-07-13 11:25:46 -07:00

the repl now resets on receiving &interrupted conditions.
2008-07-12 20:05:45 -07:00

...
trace-define-syntax to handle variable transformers.
- added primops for fx comparison functions.
2008-07-11 22:31:40 -07:00
00970f12d2
- compound conditions are made non-opaque.
...
- more tag analysis for bytevectors and friends.
2008-07-08 08:15:14 -07:00

WIP on tag analysis, annotations, and utilization.
2008-07-06 23:48:16 -07:00
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
2c8cb7dda2
fixed a bug in matching library subversion in psyntax.
2008-06-28 03:16:21 -07:00
1cd581de70
fixed char encoding error message and condition as per bug 243662.
2008-06-28 02:49:50 -07:00
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
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

Added port-position and port-has-port-position?
2008-06-19 21:49:24 -07:00
e65b39d95d
All parameters that are bound to variables now have proper names.
...
E.g., pretty-width now prints as #<procedure pretty-width>.
2008-06-19 01:58:59 -07:00
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
1bd699349a
Fixed a problem with port position accounting which was using fixnum
...
arithmetic instead of generic arithmetic.
2008-06-17 21:05:01 -07:00
333dc03f8f
(waitpid -1 #f) now returns #f if no child has died yet.
2008-06-13 22:11:51 -07:00
8f0f0abbca

...
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).

fixed incorrect handling of ".ddd" when reading from a port.
2008-06-10 18:38:06 -07:00
0939370a07
suppressing printing of file names during bootstrap.
2008-06-10 13:21:00 -07:00
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

The bottom-most exception handler now only exits.
2008-06-07 08:32:00 -07:00
9438328f55
bytevector size for doing select has been fixed. It used to be 8
...
times larger than needed.
2008-06-06 08:22:45 -07:00

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.

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;
2008-05-31 10:43:55 -07:00
6437aa98e0
- exp now understands complex numbers.

shows up to be less than the end of allocation pointer.
2008-05-25 15:32:22 -07:00

moved pretty-printing formats to their own library.
2008-05-12 00:35:19 -07:00
f05f171f28
exported pretty-format, a parameter maker for setting the pretty
...
format for various forms. The pretty format structure is not
documented yet and there is no error-checking mechanism for
verifying proper input.
2008-05-12 01:00:01 -04:00
f8b0e949d9
- syntax-case now raises a syntax violation when _ appears in the

Unhandled exception
Condition components:
1. &assertion
2. &who: with-syntax
3. &message: "pattern does not match value"
4. &irritants: ((q) #<syntax (a b c)>)
instead of the previous behavior:
> (with-syntax ([(x y) #'(a 1)] [(q) #'(a b c)]) 12)
Unhandled exception
Condition components:
1. &message: "invalid syntax"
2. &syntax:

...
into the interaction environment.
2008-05-01 15:04:43 -04:00
d49aed209a
Added (interaction-environment).
2008-05-01 06:02:36 -04:00
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.
2008-05-01 04:21:07 -04:00
1389f239fe
Added process-nonblocking which is like process but returns
...
nonblocking ports.

...
#\xHHHH "\xHHHH;" and foo\xHHHH;bar sequences.

89def78c3c
Fixed the definition of identifier? and id? in expander so that only
...
top-make-wrapped (possibly annotated) symbols are identifiers. It
used to be that symbols were considered identifiers by the previous
definition.
2008-04-28 14:01:49 -04:00
3ce6d037e4
Fixed a bug in module imports where some marks were missing in action.
...
(Note from Kent, extracted from chez scheme release notes, follows)
This always worked:
(let ()
(define-syntax from
(syntax-rules ()
[(_ m v) (let () (import m) v)]))
(module a (x) (define x 'x-of-a))
(from a x))
Didn't work before this change:
(let ()
(define-syntax x-from-a
(syntax-rules ()
[(_) (let () (import a) x)]))
(module a (x) (define x 'x-of-a))
(x-from-a))
