[ECOS] How to support mips2

[root]

Hi, all:

I want to let eCos support mips2 CPU, I add a flag -mips2 in my
mips64vr4300-elf-gcc.  I hope that  this flag will prevent the compiler
to generate some instructions which are not supported by mips2. But I meet
a problem when I compile the stub. The following is the error message.



mips64vr4300-elf-gcc -mgp32 -EL -g -nostdlib -Wl,--gc-sections -Wl,-static

I think the flag -mips2 is correct, but it is conflict with the
mips_vr4300.ld. Can someone tell me how to modify this link script so it
can support mip2?
Many thanks!
