* Don't save unrelated buffers before recompiling directory (Bug#25964)Andreas Politz2017-05-201-1/+6
| | | | | * lisp/emacs-lisp/bytecomp.el (byte-recompile-directory): Only save buffers visiting lisp files under the directory being compiled.
* Make `old-style-backquotes' variable internalPhilipp2017-05-131-2/+2
| | | | | | | | | | | | | * src/lread.c (load_warn_old_style_backquotes, Fload, read1) (syms_of_lread): Rename `old-style-backquotes' to `lread--old-style-backquotes', and clarify that it's for internal use only. * lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Rename variable. * test/src/lread-tests.el (lread-tests--old-style-backquotes): Add unit test. * emacs-lisp/bytecomp-tests.el (bytecomp-tests--old-style-backquotes): Add unit test.
* Improve unescaped character literal warningsPhilipp Stephani2017-05-131-1/+1
| | | | | | | | | | | * src/lread.c (load_warn_unescaped_character_literals) (syms_of_lread): lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Improve formatting of unescaped character literal warnings. * test/src/lread-tests.el (lread-tests--unescaped-char-literals): test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--unescaped-char-literals): Adapt unit tests.
* Remove obsolete method of changing byte-compile-dest-fileGlenn Morris2017-05-061-14/+9
| | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-dest-file): Define unconditionally.
* Warn about missing backslashes during loadPhilipp Stephani2017-05-011-0/+7
| | | | | | | | | | | | | | | | * src/lread.c (load_warn_unescaped_character_literals, Fload, read1) (syms_of_lread): Warn if unescaped character literals are found (Bug#20152). * lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Check for unescaped character literals during byte compilation. * test/src/lread-tests.el (lread-tests--unescaped-char-literals): New unit test. (lread-tests--with-temp-file, lread-tests--last-message): Helper functions for unit test. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--unescaped-char-literals): New unit test. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--with-temp-file): Helper macro for unit test.
* b-c--cond-jump-table-info: Use correct body for singleton clausesVibhav Pant2017-04-221-2/+2
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-cond-jump-table-info): When a clause's body consists of a single constant expression, use that expression as the body to be compiled. This fixes switch bytecode evaluating to nil to such clauses.
* bytecomp: Don't inline functions that use byte-switch (Bug#26518)Vibhav Pant2017-04-201-40/+46
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-unfold-bcf): Don't inline FORM if the bytecode uses the byte-switch instruction. It is impossible to guess the correct stack depth while inlining such bytecode, resulting in faulty code.
* Tweak bytecomp's loading of cl-extraGlenn Morris2017-04-181-2/+4
| | | | | * lisp/emacs-lisp/bytecomp.el: Don't force load of cl-extra in a post-bootstrap emacs where cl-loaddefs does exist.
* Fix obsolete ‘test/automated’ referencesPaul Eggert2017-03-271-1/+1
| | | | | | | | | | | | | | * Makefile.in (mostlyclean, clean, maybeclean_dirs, distclean) (bootstrap-clean, maintainer-clean): Clean ‘test’, not ‘test/automated’. Test for existence of subdirectory only for ‘test’, not for directories that should always exist. * admin/MAINTAINERS, etc/TODO, lisp/emacs-lisp/bytecomp.el: * lisp/emacs-lisp/seq.el, lisp/emacs-lisp/thunk.el: * lisp/man.el (Man-parse-man-k): * lisp/url/url-domsuf.el, make-dist: * test/file-organization.org: Fix obsolete references to test/automated.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'switch' takes two arguments from the stack: the variable to test, and a jump table (implemented as a hash-table with the appropriate :test function). By looking up the value of the variable in the hash table, the interpreter can jump to the label pointed to by the value, if any. This implementation can only be used for `cond' forms of the type `(cond ((test x 'foo) 'bar) ...)`, such that the function `test` and variable `x` is same for all clauses. * lisp/emacs-lisp/bytecomp.el: * Add (byte-compile-cond-valid-obj2-p), (byte-compile-cond-vars), (byte-compile-cond-jump-table-info), (byte-compile-jump-table-add-tag), (byte-compile-cond-jump-table), byte-compile-jump-tables. * Add defcustom `byte-compile-cond-use-jump-table'. * (byte-compile-cond): Use them. * (byte-compile-lapcode): Patch tags present in jump tables, if any. * lisp/emacs-lisp//byte-opt.el: (byte-optimize-lapcode): Add checks to some peephole optimizations to prevent them from messing up any code involving `byte-switch`. * src/bytecode.c: (exec_byte_code): Add bytecode Bswitch.
