annotate src/lastfile.c @ 5781:0853e1ec8529
Use alloca_{rawbytes,ibytes} in #'copy-file, #'insert-file-contents-internal
src/ChangeLog addition:
2014-01-20 Aidan Kehoe <kehoea@parhasard.net>
* fileio.c (Fcopy_file, Finsert_file_contents_internal):
Use alloca_{rawbytes,ibytes} here instead of the implicit alloca
on the stack; doesn't change where the buffers are allocated for
these two functions, but does mean that decisions about alloca
vs. malloc based on buffer size are made in the same place
(ultimately, the ALLOCA() macro).

| 22 /* How this works: | |
| 23 | |
| 24 Fdump_emacs dumps everything up to my_edata as text space (pure). | |
| 25 | |
| 26 The files of Emacs are written so as to have no initialized | |
| 27 data that can ever need to be altered except at the first startup. | |
| 28 This is so that those words can be dumped as sharable text. | |
| 29 | |
| 30 It is not possible to exercise such control over library files. | |
| 31 So it is necessary to refrain from making their data areas shared. | |
| 32 Therefore, this file is loaded following all the files of Emacs | |
| 33 but before library files. | |
| 34 As a result, the symbol my_edata indicates the point | |
| 35 in data space between data coming from Emacs and data | |
| 36 coming from libraries. | |
