Add global static variables for anonymous union fields. This makes sure that a debugger can find them when stepping through code, for example from the included testcase: 12 int test_it() { 13 c = 1; 14 d = 2; -> 15 a = 4; 16 return (c == 1); 17 } 18 (lldb) p a (int) $0 = 2 (lldb) p c (int) $1 = 2 (lldb) p d (int) $2 = 2 and a, c, d are all part of the file static anonymous union: static union { int c; int d; union { int a; }; struct { int b; }; }; Fixes PR19221. llvm-svn: 205952

// RUN: %clang_cc1 -emit-llvm -gdwarf-4 -triple x86_64-linux-gnu %s -o - | FileCheck %s
// Make sure that we emit a global variable for each of the members of the
// anonymous union.
static union {
int c;
int d;
union {
int a;
};
struct {
int b;
};
};
int test_it() {
c = 1;
d = 2;
a = 4;
return (c == 1);
}
