From 12576556e4aef8ae95ee93a9436e7a878f371b1c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Sun, 10 Jan 2010 18:37:07 +0000 Subject: [PATCH] llvmpipe: Update instructions. Explain how to build for windows. Both MSVC 9 and cross MinGW supported. Stop documenting LLVM 2.5 as supported. It still supported at the moment but it will soon stop being. --- src/gallium/drivers/llvmpipe/README | 39 +++++++++++++---------------- 1 file changed, 18 insertions(+), 21 deletions(-) diff --git a/src/gallium/drivers/llvmpipe/README b/src/gallium/drivers/llvmpipe/README index 0c3f00fd58f..72d9f39658f 100644 --- a/src/gallium/drivers/llvmpipe/README +++ b/src/gallium/drivers/llvmpipe/README @@ -59,27 +59,16 @@ Requirements See /proc/cpuinfo to know what your CPU supports. - - LLVM 2.5 or greater.
