From 958103c77c7857ed3ba768814ceccd944567c0f8 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 24 May 2004 17:48:21 +0000 Subject: Generates assembly dispatch stubs for SPARC. Generates different output than glsparcasm.py, but the assembled code should be the same. The seems to only work with GCC version >= 3.0. The older preprocessor doesn't like the embedded # in the GLOBL_FN macro. On the SPARC system I used, /ccs/bin/as didn't like the @function, it would only accept #function. --- src/mesa/glapi/gl_SPARC_asm.py | 134 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 134 insertions(+) create mode 100644 src/mesa/glapi/gl_SPARC_asm.py (limited to 'src/mesa/glapi/gl_SPARC_asm.py') diff --git a/src/mesa/glapi/gl_SPARC_asm.py b/src/mesa/glapi/gl_SPARC_asm.py new file mode 100644 index 0000000000..e547261af2 --- /dev/null +++ b/src/mesa/glapi/gl_SPARC_asm.py @@ -0,0 +1,134 @@ +#!/usr/bin/python2 + +# (C) Copyright IBM Corporation 2004 +# All Rights Reserved. +# +# Permission is hereby granted, free of charge, to any person obtaining a +# copy of this software and associated documentation files (the "Software"), +# to deal in the Software without restriction, including without limitation +# on the rights to use, copy, modify, merge, publish, distribute, sub +# license, and/or sell copies of the Software, and to permit persons to whom +# the Software is furnished to do so, subject to the following conditions: +# +# The above copyright notice and this permission notice (including the next +# paragraph) shall be included in all copies or substantial portions of the +# Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +# FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.
