G'day, Compiling the following example produces an error. ;; /tmp/cmucl.lisp ;; $ cmucl -noinit -eval '(compile-file "/tmp/cmucl.lisp") (defun my-funcall (a) (print a)) (my-funcall (coerce '(lambda () (print "hello'")) 'function)) ;; Output ; Python version 1.1, VM version Intel x86/sse2 on 2015-03-21 08:58:17. ; Compiling: /private/tmp/cmucl.lisp 2015-03-21 08:58:11 ; Converted MY-FUNCALL. ; Compiling DEFUN MY-FUNCALL: ; Byte Compiling Top-Level Form: ; ; ; File: /private/tmp/cmucl.lisp ; In: MY-FUNCALL (COERCE '(LAMBDA # #) 'FUNCTION) ; (COERCE '(LAMBDA # #) 'FUNCTION) ; --> VALUES PROG1 LET ; ==> ; '#<Interpreted Function (LAMBDA # #) {480513E9}> ; Error: Cannot dump objects of type EVAL:INTERPRETED-FUNCTION into fasl files. ; ; (MY-FUNCALL (COERCE '# 'FUNCTION)) ; Note: Deleting unreachable code. ; ; Compilation unit finished. ; 1 error ; 1 note ; /tmp/cmucl.sse2f written. ; Compilation finished in 0:00:00.

[cmucl-imp] Lexical environment and compiler macro functions.
by Mark Cox 15 Mar '15

15 Mar '15

G'day, CMUCL does not shadow the compiler macro function present in the global environment when introducing a function with the same name in the current lexical environment. This is demonstrated with the following example: (defun square (x) (expt x 2)) (define-compiler-macro square (&whole form arg) (declare (ignore arg)) form) (defun test () (flet ((square (arg) (declare (ignore arg)) (write "SQUARE!"))) (macrolet ((my-square (arg &environment env) (if (compiler-macro-function 'square env) `(function square) nil))) (my-square 1)))) (test) => #<Function (FLET SQUARE TEST) {48704B89}> Thanks Mark

[cmucl-imp] Happy New Year and (no) snapshot-2015-01
by Raymond Toy 02 Jan '15

02 Jan '15

Happy New Year! While it's time for the monthly snapshot, there won't be one for the first month of 2015. Nothing has really changed from the last snapshot so I decided not to make one for this month. Things that were planned or in progress didn't get done, so I'll take this opportunity to take a break from doing a snapshot. -- Ray

[cmucl-imp] Snapshot 2014-12
by Raymond Toy 05 Dec '14

05 Dec '14

Another month, another snapshot. Some of the key changes for this month: * Executables on x86 work again. They were accidentally broken when we removed support for x86. * PPC now supports executables. Currently executables can be made, and run, but they are rather buggy. * Many fixes the the LOG function, including more accurate log2 and log10 values. * (log (expt 2 n) 2) = n whenever (expt 2 n) would be a valid double-float number. * (log (expt 10 n) 10) = n whenever (expt 10 n) would be a valid double-float number. * New macros: LISP:WITH-STRING-CODEPOINT-ITERATOR and LISP:WITH-STRING-GLYPH-ITERATOR that work similarly to WITH-HASH-TABLE-ITERATOR. * Along with the iterators above, LOOP includes extensions like * (loop for cp being the codepoint of string ...) * (loop for g-string being the glyph of string ...)

[cmucl-imp] November snapshot
by Raymond Toy 04 Nov '14

04 Nov '14

The 2014-11 snapshot has been tagged and binaries will be upload soon. Major changes: * ASDF 3.1.4. * Fixed issue where TIME returned negative cycles on ppc. * :UTF is no longer an alias for :UTF-8 for external formats. * Motifd works as a 64-bit binary (thanks to Richard Kreuter) * NetBSD updated to support 64-bit time_t and related values (from Robert Swindells).
