+/* 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
+ .gcc_init section instead. */
