+# CHECK: (lldb) target variable ug
+# CHECK: (U) ug = {
+# CHECK: raw = 1688469761
+# CHECK: = (a = 1, b = 1, c = 36, d = 2, e = 36, f = 1)

+# We are testing how ValueObject deals with bit-fields when an argument is
+# passed by register. Compiling at -O1 allows us to capture this case and
+# test it.

+# typedef union
+# {
+# unsigned raw;
+# struct
+# {
+# unsigned a : 8;
+# unsigned b : 8;
+# unsigned c : 6;
+# unsigned d : 2;
+# unsigned e : 6;

+# static U ug= (U)(unsigned)0x0;
+#
+# void f(U u) {
+# printf( "%d\n", u.raw);

+#
+# int main() {
+# ug.raw = 0x64A40101;
+#
+# f(ug);
+# printf( "%d\n", ug.raw);
+# }
+#
+#
+# Compiled as follows:
+#
+# clang -O1 -gdwarf-4 weird.c -S -o weird.s
+#
+# Then the DWARF was hand modified to get DW_AT_LOCATION for ug from:
+#
+# DW_AT_location (DW_OP_addr 0x100002010, DW_OP_deref_size 0x1, DW_OP_constu 0x64a40101, DW_OP_mul, DW_OP_lit0, DW_OP_plus, DW_OP_stack_value)
+#
+# to this:
+#
+# DW_AT_location (DW_OP_constu 0x64a40101, DW_OP_stack_value)
+#
+# to work-around a seperate bug.
+#
+# clang is built from llvm.org and the last commit was:
