* lisp/emacs-lisp/byte-lexbind.el (byte-compile-lforminfo-analyze):
Understand the :fun-body case for catch, save-window-excursion, and
condition-case.
(byte-compile-maybe-push-heap-environment): No need when nclosures is
zero and byte-compile-current-num-closures is -1.
* lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Fix `fun' that was not
renamed to `bytecomp-fun'.
* lisp/emacs-lisp/cconv.el (cconv-not-lexical-var-p): New function.
(cconv-freevars): Use it.
(cconv-closure-convert-rec): Avoid `position'.
(cconv-analyse-function): New function.
(cconv-analyse-form): Use it. `inclosure' can't be nil any more.
Check lexical vars at let-binding time rather than when referenced.
For defuns to be in an empty environment and lambdas to take lexical args.
Pay attention to the need to build closures in catch, unwind-protect,
save-window-excursion, condition-case, and track-mouse.
Fix defconst/defvar handling.
(byte-compile-unwind-protect, byte-compile-track-mouse)
(byte-compile-condition-case, byte-compile-save-window-excursion):
Provide a :fun-body alternative, so that info can be propagated from the
surrounding context, as is the case for lexical scoping.
* lisp/emacs-lisp/cconv.el (cconv-mutated, cconv-captured)
(cconv-captured+mutated, cconv-lambda-candidates): Fix up declaration.
(cconv-freevars): Minor cleanup. Fix handling of the error var in
condition-case.
* lisp/emacs-lisp/bytecomp.el (byte-compile-output-docform): Fix up use of
print-number-table.
* src/print.c (PRINT_NUMBER_OBJECT, PRINT_NUMBER_STATUS): Remove.
(print_preprocess): Fix handling of uninterned symbols in last change.
* src/eval.c (apply_lambda, funcall_lambda): Remove lexenv arg.
(Feval): Always eval in the empty environment.
(eval_sub): New function. Use it for all calls to Feval that should
evaluate in the lexical environment of the caller.
Pass `closure's as is to apply_lambda.
(Ffuncall): Pass `closure's as is to funcall_lambda.
(funcall_lambda): Extract lexenv for `closure's, when applicable.
Also use lexical scoping for the &rest argument, if applicable.
* src/lisp.h (eval_sub): Declare.
* src/lread.c (readevalloop): Remove `evalfun' argument.
* src/print.c (Fwith_output_to_temp_buffer):
* src/data.c (Fsetq_default): Use eval_sub.
* lisp/emacs-lisp/bytecomp.el (byte-compile-condition-case): Use push.
See thread http://lists.gnu.org/archive/html/emacs-devel/2010-09/msg00795.html
* src/emacs.c (fatal_error_signal): Also run Fkill_emacs on SIGINT.
(main) [!WINDOWSNT]: Handle SIGINT with fatal_error_signal
in batch-mode.
(Fkill_emacs): Doc fix. Also run the hook in batch mode.
(kill-emacs-hook): Doc fix.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Use kill-emacs-hook to
delete tempfile if interrupted during compilation.
* doc/lispref/os.texi (Killing Emacs): Hook now runs in batch mode.
* etc/NEWS: Mention these changes.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file-form-defvar):
(byte-compile-defvar, byte-compile-cl-warn):
Start warnings with lower-case, like the majority.
`lexical' for warnings related to lexical scoping.
(byte-compile-file-form-defvar, byte-compile-defvar): Warn about
global vars which don't have a prefix and could hence affect lexical
scoping in unrelated files.
Don't macroexpand before evaluating in eval-and-compile, in case
`body's macro expansion uses macros and functions defined in itself.
* src/bytecode.c (exec_byte_code):
* src/eval.c (Ffunctionp): Fix up int/Lisp_Object confusions.
* emacs-lisp/bytecomp.el (byte-compile-set-default): New function.
(byte-compile-setq-default): Optimize for the
single-var case and don't call byte-compile-form in this case to avoid
inf-loop with byte-compile-set-default.
(byte-compile-file-form-define-abbrev-table)
(byte-compile-file-form-custom-declare-variable)
(byte-compile-variable-ref, byte-compile-defvar):
Whether or not a warning is enabled should only affect whether we issue
the warning, not whether or not we collect the relevant data.
Eg warnings can be turned on and off throughout the course of a file.
as an option.
(byte-compile-callargs-warn, byte-compile-arglist-warn)
(display-call-tree): Update for byte-compile-fdefinition possibly
returning `(macro lambda ...)'. (Bug#4778)
(byte-compile-variable-ref, byte-compile-setq-default):
Respect `constants' member of byte-compile-warnings.
