From 7e4d9d5d456916f51cb40ef646fad5b0a467f4b1 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Thu, 2 Feb 2012 11:48:13 -0800 Subject: win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof.
