Modifying patch from: marian.buschsieweke@ovgu.de
The code accessing the floating point control/status register, namely
#define __cfc1(__fcsr) __asm __volatile("cfc1 %0, $31" : "=r" (__fcsr)
does not compile with mips16. This changed the makefile to pass -mno-mips16 to avoid the following
compiler error:
mips-mti-elf fails with "Error: unrecognized opcode `cfc1 $3,$31'"
