Using GCC for MIPS 4K (JADE) CPUs

[Robert Ward]

Dear all,

I am attempting to build code for the MIPS 4Km,p,c CPUs using mips-elf
(version 2.95.1 under cygwin32-B21.1).  I understand that support for
MIPS32 architecture will be availble next year, but in the mean time I
have been trying to use the switches -mcpu=r4k -mips2, and I get a "link
error ISA mismatch (-mips3) with (-mips1)" for what appears to be a
temporary file.  The code compiles successfully with -mips1 or -mips3,
but not with -mips2.  

Am I missing something? I don't understand the cause of this error.
Any ideas on how to get around this problem?

Regards
Rob.
