SDE MIPS - unfortunately this is 2.9x compiler. Which should be perfectly find for the kernel. And no, SDE isn't really a 2.96-based compiler with _vastly_ improved code generation for MIPS processors. Less than a week ago SDE 5 was released which is based on gcc 3.4 and similarly contains a large number of mostly MIPS-specific improvments. > 2.
