The code drops into newlib's libm in a particular way which may require some refactoring. fenv.h is shared across all ports and machine/fenv.h is where port code goes. There must be an architecture specific file for each method. But the entire implementation could go in one file and the others be stubs. The i386 does this. --joel > > > <https://github.com/NetBSD/src/tree/trunk/lib/libm/arch/aarch64> > > Thanks > -Eshan > _______________________________________________ > devel mailing list > devel@rtems.org > http://lists.rtems.org/mailman/listinfo/devel
