Clean up some of the bitrot affecting the CANNOT_DUMP code. This lets the build succeed again, and fixes the testing framework so that most test cases now pass. About twenty test cases still fail, though, and we still have Bug#24974. * configure.ac (CANNOT_DUMP): Now empty if CANNOT_DUMP. (SYSTEM_MALLOC): Now true if CANNOT_DUMP. There should no longer be any point to messing with a private memory allocator unless Emacs is dumping. * src/alloc.c (alloc_unexec_pre, alloc_unexec_post, check_pure_size): * src/image.c (reset_image_types): * src/lastfile.c (my_endbss, _my_endbss, my_endbss_static): Do not define if CANNOT_DUMP. * src/emacs.c (might_dump) [CANNOT_DUMP]: Now always false and local. (daemon_pipe) [!WINDOWSNT]: Now static. * test/Makefile.in (mostlyclean): Remove *.tmp files. (make-test-deps.mk): Elide CANNOT_DUMP chatter.

/* How this works:
|
|
|
|
Fdump_emacs dumps everything up to my_edata as text space (pure).
|
|
|
|
The files of Emacs are written so as to have no initialized
|
|
data that can ever need to be altered except at the first startup.
|
|
This is so that those words can be dumped as shareable text.
|
|
|
|
It is not possible to exercise such control over library files.
|
|
So it is necessary to refrain from making their data areas shared.
|
|
Therefore, this file is loaded following all the files of Emacs
|
|
but before library files.
|
|
As a result, the symbol my_edata indicates the point
|
|
in data space between data coming from Emacs and data
|
|
coming from libraries.
