From 1ad4471526c70d073b19bd551dc4193457d1e610 Mon Sep 17 00:00:00 2001 From: Hendrik Leppkes Date: Tue, 28 Jun 2016 11:48:29 +0200 Subject: [PATCH] configure: disable the new optimizer in Visual Studio 2015 Update 3 Visual Studio 2015 Update 3 introduced a new SSA optimizer, however it unfortunately causes miscompilations. Until it is fixed, the new optimizations are disabled and should be re-checked on subsequent compiler releases. Fixes recent FATE failure of fate-lavf-pam on VS2015. --- configure | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/configure b/configure index 22298df88c7..126d0d6334c 100755 --- a/configure +++ b/configure @@ -6207,6 +6207,10 @@ __declspec($_restrict) void* foo(int); EOF fi check_func strtoll || add_cflags -Dstrtoll=_strtoi64 + # the new SSA optimzer in VS2015 U3 is mis-optimizing some parts of the code + # this flag should be re-checked on newer compiler releases and put under a + # version check once its fixed + check_cflags -d2SSAOptimizer- fi for pfx in "" host_; do -- 2.39.5
