I have impression that fpu_control.h has the same interface for all HW platforms, so conditional compilation is not required.

I had to modify some packages to pass their testsuites. One of the packages was mpfr, the float tests will fail with RunFast mode. In arm case the _FPU_IEEE mode is different from the default mode, which does not have the FPU exceptions set on. Any code that calls this _FPU_SETCW should also be #ifdef __arm__. -Juha On 12/01/11 11:21, Moiseichuk Leonid (Nokia-MS/Helsinki) wrote: > Yes, we have. Juha could provide it.
