From 16017c48547960539fcadb1f91d252124f442482 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 12 Jan 2015 14:38:28 +0000 Subject: softfloat: Clarify license status MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code in the softfloat source files is under a mixture of licenses: the original code and many changes from QEMU contributors are under the base SoftFloat-2a license; changes from Stefan Weil and RedHat employees are GPLv2-or-later; changes from Fabrice Bellard are under the BSD license. Clarify this in the comments at the top of each affected source file, including a statement about the assumed licensing for future contributions, so we don't need to remember to ask patch submitters explicitly to pick a license.
