Thanks for your elaboration.It helps a lot. I want to submit a v3 patch like:
#if cpu_has_fpu # error "Forcing `cpu_has_fpu' to non-zero is not supported" #endif
but this will cause the link error if not combined with the fix:
MIPS: IP30: Remove incorrect `cpu_has_fpu' override
Maybe I should submit one first, and see how it goes then.
