be saved, because it may be overwritten by a BLOCK or TAGBODY inside
the normal exit form.
2) Implement Invocation History Stack as a chain of stack-allocated records.
3) In compiled TAGBODY forms, replace tags with numbers to save space.
LAMBDA-PARAMETERS-LIMIT are both 64. Up to C-ARGUMENTS-LIMIT may be
passed to a function using C calling conventions. If the function is
to retrieve more arguments, (for instance through a &rest variable),
this can be done, but then the arguments have to be pushed on the lisp
stack. This method allows us to raise the CALL-ARGUMENTS-LIMIT up to
MOST-POSITIVE-FIXNUM. From a users point of view, there is no visible
change, excep the fact that a function may receive more arguments.
The function apply() has been replaced with cl_apply_from_stack().
The former took a pointer to the list of arguments. The latter assumes
that the last "narg" elements on the lisp stack are the arguments of
the function.
object which could not be printed or readed so that it could be
used to mark unbound slots in classes. Now the function SI:UNBOUND
performs the same task
- Enable simple allocator to use mmap()
- Rewrite cmpwt.lsp so that it produces files with short lines and ANSI strings
- Fix mkdir so that it accepts a parameter for the mode
+Deftype BIT-VECTOR would not expand to a vector type.
+Each compiled file has an entry point whose name is either
init_CODE() or another name based on the name of the source file.
The algorithm for computing these names has been slightly changed
so that the entry points of ECLS's own library do not conflict with
user defined entry points.
+A LET/LET* form in which the initializers for a variable have not
the expected type produce a warning, but the code is accepted. For
instance (LET (V) (DECLARE (TYPE FIXNUM V)) (SETQ V 1)) now
compiles.
+(SETF name), where name is a symbol, is now a valid function name in all
contexts. It is accepted by DEFUN, FUNCTION, FBOUNDP, FMAKUNBOUND, etc,
and it can be the on the function position in any form.
+New specialized arrays for (UNSIGNED-BYTE 8) and (SIGNED-BYTE 8).
Fixed bug in the compiler for MULTIPLE-VALUE-BIND: resulting code would not
undo bindings of special variables.
Optimized statements like (let ((*special-var* *special-var*)) ...) where
*special-var* is a special variable.
These hash tables can be dumped to help files which are understood by ECLS.
Most documentation strings have been moved back to the lisp source files
from which "SYS:help.doc" is built.
- The value of *package* is correctly set and restored while loading
compiled code. This way, 'ecls -eval "(print *package*)"' produces
the expected result #<"COMMON-LISP-USER" package>
- COMPILE-FILE now outputs three values.
- The value of si::*keep-definitions* determines whether the
interpreter keeps the source of defined functions, for later use
with COMPILE and DISASSEMBLE. For instance,
> (set si::*keep-definitions* t)
> (defun foo (x) (1+ x))
> (compile 'foo)
> (foo 2)
3
> (compile 'foo)
;;; Error ....
These definitions are lost once the function is compiled, hence
the second error message.
This stack is also used to build the Invocation History records, which keep
track of which functions are called and which are their local environments.
With these changes, the debugger now works to the extend that it inspecting
these Invocation History Records with :backtrace, :up, :down, :variables,
now output the rights values.
Bit fiddling operations with negative fixnums now work.
Remove unportable code of the type va_list d = cs.
Simplify gathering of &rest and &key arguments in compiled code.
