2010-07-23 Andreas Schwab * eval.c (funcall_funvec): Replace bcopy by memcpy. 2010-06-18 Stefan Monnier * eval.c (Fspecial_variable_p): Rename from `specialp'. 2010-06-15 Stefan Monnier * bytecode.c (exec_byte_code): * eval.c (Ffunctionp): Fix up int/Lisp_Object confusions. 2008-04-23 Miles Bader * eval.c (Ffunctionp): Return nil for special forms. (Qunevalled): New variable. (syms_of_eval): Initialize it. 2007-10-18 Miles Bader * eval.c (FletX): Test the type of VARLIST rather than just !NILP. (Flet): Use XCAR instead of Fcar. 2007-10-16 Miles Bader * alloc.c (make_funvec, Fpurecopy): Set the pseudo-vector type. 2006-02-10 Miles Bader * eval.c (Ffunctionp): Supply new 2nd arg to Findirect_function. 2005-03-04 Miles Bader * eval.c (FletX): Update Vinterpreter_lexical_environment for each variable we bind, instead of all at once like `let'. 2004-08-09 Miles Bader Changes from merging the funvec patch: * eval.c (Feval, Ffuncall): Don't special-case vectors. (funcall_lambda): Use FUNVEC_SIZE. (Fcurry): Remove function. Merge funvec patch. 2004-04-10 Miles Bader * eval.c (Fspecialp): New function. (syms_of_eval): Initialize it. 2004-04-03 Miles Bader * eval.c (Feval): If a variable isn't bound lexically, fall back to looking it up dynamically even if it isn't declared special. 2002-08-26 Miles Bader * bytecode.c (Fbyte_code): Fsub1 can GC, so protect it. 2002-06-12 Miles Bader Lexical binding changes to the byte-code interpreter: * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, Bvec_ref, Bvec_set) (BdiscardN): New constants. (exec_byte_code): Rename from `Fbyte_code'. Implement above new bytecodes. Add ARGS-TEMPLATE, NARGS and ARGS parameters, and optionally use them push initial args on the stack. (Fbyte_code): New function, just call `exec_byte_code'. Add additional optional arguments for `exec_byte_code'. (Qand_optional, Qand_rest): New extern declarations. * eval.c (Fcurry, Ffunctionp): New functions. (syms_of_eval): Initialize them. (funcall_lambda): Call `exec_byte_code' instead of Fbyte_code. If a compiled-function object has a `push-args' slot, call the byte-code interpreter without binding any arguments. (Ffuncall): Add support for curried functions. * lisp.h (Fbyte_code): Declare max-args as MANY. (exec_byte_code): New declaration. Lexical binding changes to the lisp interpreter: * lisp.h (struct Lisp_Symbol): Add `declared_special' field. (apply_lambda): Add new 3rd arg to decl. * alloc.c (Fmake_symbol): Initialize `declared_special' field. * eval.c (Vinterpreter_lexical_environment): New variable. (syms_of_eval): Initialize it. (Fsetq): Modify SYM's lexical binding if appropriate. (Ffunction): Return a closure if within a lexical environment. (Flet, FletX): Lexically bind non-defvar'd variables if inside a lexical environment. (Feval): Return lexical binding of variables, if they have one. Pass current lexical environment to embedded lambdas. Handle closures. (Ffuncall): Pass nil lexical environment to lambdas. Handle closures. (funcall_lambda): Add new LEXENV argument, and lexically bind arguments if it's non-nil. Bind `interpreter-lexenv' if it changed. (apply_lambda): Add new LEXENV argument and pass it to funcall_lambda. (Fdefvaralias, Fdefvar, Fdefconst): Mark the variable as special. (Qinternal_interpreter_environment, Qclosure): New constants. (syms_of_eval): Initialize them. (Fdefun, Fdefmacro): Use a closure if lexical binding is active. * lread.c (defvar_bool, defvar_lisp_nopro, defvar_per_buffer) (defvar_kboard, defvar_int): Mark the variable as special. (Vlexical_binding, Qlexical_binding): New variables. (syms_of_lread): Initialize them. (Fload): Bind `lexically-bound' to nil unless specified otherwise in the file header. (lisp_file_lexically_bound_p): New function. (Qinternal_interpreter_environment): New variable. * doc.c (Qclosure): New extern declaration. (Fdocumentation, store_function_docstring): Handle interpreted closures. ;; arch-tag: 7cf884aa-6b48-40cb-bfca-265a1e99b3c5
