EVMK2H: using -mfpu=neon or not using it make no difference

Part Number: EVMK2H

hello

Compiler: GNU v7.2.1

i was comparing asm code generated while using -mfpu=neon and i noticed that its asm code is exactly same as asm code whit out -mfpu=neon. i also run a performance test and result for both code  was the same.

now question:

is using -mfpu=neon has no effect and neon unit is still disable? or it's the other way around, i mean neon unit is always in use no matter what kind of options you feed to compiler?

anyway how i can control it? because it seem existence of -mfpu=neon has no effect on anything
