branch: master
commit 90655e4bc01ba8d00be3281d13cc771b53e75b43
Author: Eli Zaretskii <eliz@gnu.org>
Commit: Eli Zaretskii <eliz@gnu.org>
Make the build of source tarball produce *.eln files
* lisp/emacs-lisp/comp.el (batch-native-compile): Accept an
optional argument; if non-nil, place the .eln file as appropriate
for building a source tarball.
* doc/lispref/compile.texi (Native-Compilation Functions):
Document the new optional argument of 'batch-native-compile'.
* lisp/Makefile.in (.PHONY, $(THEFILE)n) [HAVE_NATIVE_COMP]: New
targets.
* src/Makefile.in (%.eln) [HAVE_NATIVE_COMP]: New recipe.
(all) [HAVE_NATIVE_COMP]: Add ../native-lisp to prerequisites.
(elnlisp) [HAVE_NATIVE_COMP]: New list of *.eln files.
(../native-lisp) [HAVE_NATIVE_COMP]: New recipe.
* src/verbose.mk.in (AM_V_ELN): New macro.

This function runs native-compilation on files specified on the Emacs
command line in batch mode. It must be used only in a batch execution
of Emacs, as it kills Emacs upon completion of the compilation. If
one or more of the files fail to compile, the Emacs process will
attempt to compile all the other files, and will terminate with a
