FPU Exception masking

I need to parse through raw data where fields are aligned on 4 bytes
and either contain a floating point value, or garbage, and filter out
float values between 100 and 5000

In windows I can use  SetMXCSR (and Set8087CW) to disable exceptions
when the data is garbage but that isn't available in ARM
Is there a generic way to do this or will I have to result to ASM, or
use a soft fpu implementation that skips those exceptions ?

Edit: Just noticed SetExceptionMask()  Is this what I am looking for ?
Edit2: Yup, it's fixed
