From 1deff3dca1b11fd7089bb641f6ee99adedeb8d0b Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Wed, 15 May 2013 20:33:45 +0200 Subject: [PATCH] Use movq for 64-bit operations The EXTRACT_WORDS64 and INSERT_WORDS64 macros use movd for a 64-bit operation. Somehow gcc manages to turn this into movq, but LLVM won't. 2013-05-15 Peter Collingbourne * sysdeps/x86_64/fpu/math_private.h (MOVQ): New macro. (EXTRACT_WORDS64) Use where appropriate.
