-/* 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
