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