# DSP ASE supported for MIPS32 or MIPS64 Release 2 cores only. It is not
# safe to unconditionnaly use the assembler -mdsp / -mdspr2 switches
# here because the compiler may use DSP ASE instructions (such as lwx) in
# code paths where we cannot check that the CPU we are running on supports it.
# Proper abstraction using HAVE_AS_DSP and macros is done in
# arch/mips/include/asm/mipsregs.h.
