From efd4829edfa036c5506a16d05c91268faa1f6332 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Fri, 8 Dec 2017 17:13:19 +0000 Subject: include/fpu/softfloat: add some float16 constants MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This defines the same set of common constants for float 16 as defined for 32 and 64 bit floats. These are often used by target helper functions. I've also removed constants that are not used by anybody.
