N32 Migration Requirements

In order to implement n32, Silicon Graphics provides the following to our customers:

A compiler that supports n32. (The 6.1 version of MIPSpro compilers supports n32).
A kernel that supports n32. (IRIX 6.1 supports n32).
N32 versions of each library.

To take advantage of the n32 ABI, our customers must:

Install n32 OS, compiler, and all n32 libraries.
Rewrite Assembly code to conform to n32 guidelines.
Prototype C functions that use varargs.
Recompile all the code with the compiler that supports n32 (use -n32 on the command line). Makefile changes are needed only if explicit library paths are used.
