From 5d61fa4e68b7eb6d481a37efdbb35fdce675a6ad Mon Sep 17 00:00:00 2001
From: Tobias Droste <tdroste@gmx.de>
Date: Wed, 8 Nov 2017 10:44:19 +0100
Subject: gallivm: Use new LLVM fast-math-flags API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
LLVM 6 changed the API on the fast-math-flags:
https://reviews.llvm.org/rL317488
NOTE: This also enables the new flag 'ApproxFunc' to allow for
approximations for library functions (sin, cos, ...). I'm not completly
convinced, that this is something mesa should do.
