<div>
<pre>OpenCL spec s6.5.2 disallows initializers on __local addr space variables, but
even when they are not initialized in the source clang adds initializers for
the class type variables in IR.
Example:
1 class C{
2 int i;
3 };
4
5 kernel void test()
6 {
7 __local int i;
8 __local C ii;
9 }
Produces in IR:
@_ZZ4testvE1i = internal addrspace(3) global i32 undef, align 4
@_ZZ4testvE2ii = internal addrspace(3) global %class.C zeroinitializer, align 4</pre>
