23 | /* How this works: | |
24 | ||
25 | Fdump_emacs dumps everything up to my_edata as text space (pure). | |
26 | ||
27 | The files of Emacs are written so as to have no initialized | |
28 | data that can ever need to be altered except at the first startup. | |
29 | This is so that those words can be dumped as sharable text. | |
30 | ||
31 | It is not possible to exercise such control over library files. | |
32 | So it is necessary to refrain from making their data areas shared. | |
33 | Therefore, this file is loaded following all the files of Emacs | |
34 | but before library files. | |
35 | As a result, the symbol my_edata indicates the point | |
36 | in data space between data coming from Emacs and data | |
37 | coming from libraries. | |
