Add definitions for bits in condition code register and the load store unit control registers. Move tstate definitions to their own file. Submitted by: tmm 2001-08-20 23:34:46 +00:00			`/*-`
sys/sparc64: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-11-27 15:10:39 +00:00			`* SPDX-License-Identifier: BSD-2-Clause-FreeBSD`
