<pre>In <a href="https://reviews.llvm.org/D59518">https://reviews.llvm.org/D59518</a> it was observed that dumping a
location-list entry with an empty (zero-length) location expression doesn't
provide an explicit indication that the expression is in fact empty. Here's
the snippet from llvm/test/MC/X86/dwarf-size-field-overflow.test:
+# CHECK-NEXT: DW_AT_location (0x00000000
+# CHECK-NEXT: [0x0000000000000000, 0x0000000000000008): )
+# CHECK-NEXT: DW_AT_name ("self")
It would be nice to dump this in a less subtle way.</pre>
