+ Our linker uses -m aixppc64 for xcoff64 support. The choice for the
+ correct emulation is done in collect2.c via the environmental varible
+ LDEMULATION.
+
+ binitfini has special handling in the linker backend. The native linker
+ uses the arguemnts to generate a table of init and fini functions for
+ the executable. The important use for this option is to support aix 4.2+
+ c++ constructors and destructors. This is tied into gcc via collect2.c.
+ The function table is accessed by the runtime linker/loader by checking if
+ the first symbol in the loader symbol table is "__rtinit". The native
+ linker generates this table and the loader symbol. The gnu linker looks
+ for the symbol "__rtinit" and makes it the first loader symbol. It is the
+ responsiblity of the user to define the __rtinit symbol. The format for
+ __rtinit is given by the aix system file /usr/include/rtinit.h. You can
+ look at collect2.c to see an example of how this is done for 32 and 64 bit.
+ Below is an exmaple of a 32 bit assembly file that defines __rtinit.
