a6fea4e63e After reading an object, READ should skip whitespaces until it fints the 
beginning of a new line, the EOF, or a new token. This way (READ-LINE)
at the prompt, produces the expected result instead of an empty line.

7a58f94bd0 We need machines.h do define unix.h. 2002-11-21 13:41:22 +00:00

cfb16c1920 + The tests for the type and size of cl_fixnum have been grouped. 
FIXNUM_BITS and CHAR_BIT do not rely now on "char" being 8-bit
  large.
+ All configuration settings are now grouped in config.h. This file
  has two parts, and the second one, containing flags which are only
  needed during the build process, is deleted when installing ECL.
+ File critical.h merged into lwp.h.

c08c51ab4a Instead of defining cl_alloc* stuff, make them alias of functions in the Boehm-Weiser garbage collector, to save space. 2002-11-18 12:50:54 +00:00

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

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.

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

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.
