<div>We are using the POSIX API with RTEMS 4.10 on a leon3 processor. We would like to take advantage of the leon3’s floating point hardware, however, in order to get our software to run without generating the “unexpected trap (0x4) fp disabled” error we have
to make sure that we compile (and link) everything with the –msoft-float option. This seems to preclude use of processor’s hardware floating point.</div>
<div> </div>
<div> I have seen references to how to go about setting the RTEMS floating point task attribute but nothing for the POSIX API. What do we need to do to enable hardware FPU usage with the POSIX API?</div>
