   2  * In this file we wrap QEMU FP functions to look like softfloat/testfloat's,
   3  * so that we can use the testfloat infrastructure as-is.
   4  *
   5  * This file must be included directly from fp-test.c. We could compile it
   6  * separately, but it would be tedious to add declarations for all the wrappers.
