FreddyYe added a comment.
Notice that these two changes are both expected since a more complete feature
list won't influence the _cpu_dispatch/specific multiversion to not work.
================
Comment at: clang/test/CodeGen/attr-cpuspecific.c:47
// LINUX: %[[FEAT_INIT:.+]] = load i32, ptr getelementptr inbounds ({ i32,
i32, i32, [1 x i32] }, ptr @__cpu_model, i32 0, i32 3, i32 0), align 4
-// LINUX: %[[FEAT_JOIN:.+]] = and i32 %[[FEAT_INIT]], 1023
-// LINUX: %[[FEAT_CHECK:.+]] = icmp eq i32 %[[FEAT_JOIN]], 1023
+// LINUX: %[[FEAT_JOIN:.+]] = and i32 %[[FEAT_INIT]], 525311
+// LINUX: %[[FEAT_CHECK:.+]] = icmp eq i32 %[[FEAT_JOIN]], 525311
----------------
This value change is because the feature list of ivybridge described in
X86TargetParser.def before missed feature "pclmul".

// WINDOWS: %[[FEAT_INIT:.+]] = load i32, ptr getelementptr inbounds ({ i32,
i32, i32, [1 x i32] }, ptr @__cpu_model, i32 0, i32 3, i32 0), align 4

+// WINDOWS: %[[FEAT_CHECK:.+]] = icmp eq i32 %[[FEAT_JOIN]], 525311
----------------
This value change is because the feature list of knl described in
X86TargetParser.def before missed feature "bmi2" and "aes".
