395 | /* For unexec to work on Alpha systems, we need to put Emacs' |
396 | initialized data into a separate section from the CRT initialized | |
397 | data (because the Alpha linker freely reorders data variables, even | |
398 | across libraries, so our data and the CRT data get intermingled). | |
399 | ||
400 | Starting with MSVC 5.0, we must also place the uninitialized data | |
401 | into its own section. VC5 intermingles uninitialized data from the CRT | |
402 | between Emacs' static uninitialized data and its public uninitialized | |
403 | data. A separate .bss section for Emacs groups both static and | |
517d7b9f | 404 | public uninitialized together. |
7f470eff | 405 | |
517d7b9f | 406 | Note that unexw32.c relies on this fact, and must be modified |
7f470eff GV |
407 | accordingly if this section name is changed, or if this pragma is |
408 | removed. Also, obviously, all files that define initialized data | |
409 | must include config.h to pick up this pragma. */ | |
