+ Consult the following documents/files for a description of the

+ NEXTSTEP documents of the Mach-O format. The tool otool dumps the
+ mach header (-h option) and the load commands (-l option) in a
+ Mach-O file. The tool nm on Mac OS X displays the symbol table in
+ a Mach-O file. For examples of unexec for the Mach-O format, see
+ the file unexnext.c in the GNU Emacs distribution, the file
+ unexdyld.c in the Darwin port of GNU Emacs 20.7, and unexdyld.c in
+ the Darwin port of XEmacs 21.1. Also the Darwin Libc source
+ contains the source code for malloc_freezedry and malloc_jumpstart.
+ Read that to see what they do. This file was written completely
+ from scratch, making use of information from the above sources. */
+
+/* The Mac OS X implementation of unexec makes use of Darwin's `zone'
+ memory allocator. All calls to malloc, realloc, and free in Emacs
+ are redirected to unexec_malloc, unexec_realloc, and unexec_free in
+ this file. When temacs is run, all memory requests are handled in
+ the zone EmacsZone. The Darwin memory allocator library calls
+ maintain the data structures to manage this zone. Dumping writes
+ its contents to data segments of the executable file. When emacs
+ is run, the loader recreates the contents of the zone in memory.
+ However since the initialization routine of the zone memory
+ allocator is run again, this `zone' can no longer be used as a
+ heap. That is why emacs uses the ordinary malloc system call to
+ allocate memory. Also, when a block of memory needs to be
+ reallocated and the new size is larger than the old one, a new
+ block must be obtained by malloc and the old contents copied to
+ it. */
+
+/* Peculiarity of the Mach-O files generated by ld in Mac OS X
+ (possible causes of future bugs if changed).
+
+ The file offset of the start of the __TEXT segment is zero. Since
+ the Mach header and load commands are located at the beginning of a
+ Mach-O file, copying the contents of the __TEXT segment from the
+ input file overwrites them in the output file. Despite this,
+ unexec works fine as written below because the segment load command
+ for __TEXT appears, and is therefore processed, before all other
+ load commands except the segment load command for __PAGEZERO, which
+ remains unchanged.
+
+ Although the file offset of the start of the __TEXT segment is
+ zero, none of the sections it contains actually start there. In
+ fact, the earliest one starts a few hundred bytes beyond the end of
+ the last load command. The linker option -headerpad controls the
+ minimum size of this padding. Its setting can be changed in
+ s/darwin.h. A value of 0x300, e.g., leaves room for about 15
+ additional load commands for the newly created __DATA segments (at
+ 56 bytes each). Unexec fails if there is not enough room for these
+ new segments.
+
+ The __TEXT segment contains the sections __text, __cstring,
+ __picsymbol_stub, and __const and the __DATA segment contains the
+ sections __data, __la_symbol_ptr, __nl_symbol_ptr, __dyld, __bss,
+ and __common. The other segments do not contain any sections.
+ These sections are copied from the input file to the output file,
+ except for __data, __bss, and __common, which are dumped from
+ memory. The types of the sections __bss and __common are changed
+ from S_ZEROFILL to S_REGULAR. Note that the number of sections and
+ their relative order in the input and output files remain
+ unchanged. Otherwise all n_sect fields in the nlist records in the
+ symbol table (specified by the LC_SYMTAB load command) will have to
+ be changed accordingly.
