/* The GNU and SGI linkers differ in their implementation of -init and -fini.
29
   With the GNU linker, there can only be a single -init option, and the
30
   linker simply sets DT_INIT to that value.  gcc's initialization and
31
   finalization code can go directly in .init, with the prologue and
32
   epilogue of the main initialization routine being provided by external
33
   object files (*crti.o and *crtn.o in this case).
34
 
35
   The SGI linker instead accepts several -init options.  It will set DT_INIT
36
   to a linker-created function (placed in .init) that calls each of the -init
37
   functions in turn.  If there is any user code in .init, this linker-created
38
   function will be placed after it.  Note that such user code is not treated
39
   specially; it will only be called if the -init options arrange for it to
40
   be called.
41
 
42
   In theory, the SGI model should allow the crti, crtn and intermediate code
43
   to go in .init, just like it can with the GNU linker.  However, doing this
44
   seems to confuse the linker and triggers an internal error:
45
 
46
      ld32: FATAL   2  : Internal: at ../../ld/mips_code.c mips_code_fixup()
47
         text section overflow!
48
 
49
   (seen with MIPSpro 7.30).  We therefore put everything in a special
50
   .gcc_init section instead.  */
