aefdb1995b Introduce ecl_register_static_root() to register C static variables as containing pointers for garbage collection. Make ecl_register_static_root() do nothing in the Boehm-Weiser GC, because it already scans the whole data segment. 2002-11-18 12:48:58 +00:00

bfcc390d7f Merge more functions (copy_tree, copy_list, etc), so that only the lisp version is used and this one takes a fixed number of arguments. 2002-11-18 11:23:52 +00:00

72ceea3d3c Fixed FILE-NAMESTRING, implemented ENSURE-DIRECTORIES-EXIST, and added a 
WITH-COMPILATION-UNIT which does nothing.

9bdb35ee31 Make the behavior of "**" in logical pathnames more intuitive. For 
instance, now "HOME:FOO.LISP" matches the translation rule
("**/*.*" "~/**/*.*"), which formerly it did not. Also, add a logical
hostname for the home directory.

914f959599 1) Fix error in UNWIND-PROTECT forms: the destination frame nlj_fr has to 
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.

b0ce08d0ea Changes towards 0.7b comprise naming and calling conventions. See CHANGELOG. 2002-11-04 14:08:24 +00:00

a9e4edf4d0 The calling conventions have been changed. SI::C-ARGUMENTS-LIMIT and 
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.

39539e5714 Add new operator OP_LFUNCTION and remove OP_CALL/OP_PCALL. This results in 
a simplification of the code for OP_FUNCTION, which may assume that the
function to be searched is a global.

3c7fe4535b Instead of having gcall() work like funcall(), create a function 
[va_]compute_method() which computes the method we really want to call,
and use this function inside funcall(), apply(), etc.

59a26b4751 Use same link_call() with and without CLOS. The use of static variables is 
not thread safe.

29734ae79b New functions SI:SAFE-EVAL and cl_safe_eval() allow the user to evaluate 
code with errors without jumping into the debugger. Useful when embedding
ECL in other programs.

4c6036b3f8 Changed the algorithm of the list reader. A dot which is not escaped is read as 
a symbol SI::. which is recognized by LEFT-PARENTHESIS-READER. This avoids
using global variables "in_list_flag" and "dot_flag". No need for function
read_object_recursive(), since read_object() is equivalent to it.

symbols. The old GC still has a leak, so disable it.

23ee878e59 All symbols belonging to the LISP package and to the C core, are 
kept in a single array, "cl_symbols". The translator "dpp" and the
routine SI::MANGLE-NAME, output the right name for any symbol
which is in this array.

356e6b9235 ECL now uses a hashtable to store objects when *PRINT-CIRCLE* is 
on. This hashtable is not cleared when calling PRINT-OBJECT, so
that circularities are also detected inside these methods.
