EC		 1/*
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.
