What are you talking about? The problem we have is
-march=r4100 -mips2
doesn't work. That is we cannot assemble code which contains MIPS 2 plus
instructions like "standby" which is specific to R4100. I want
1. It should assemble.
2. The R4100 bit is set so that the loader can check if the binary is valid
for the hardware.
