[PATCH] D59687: [DebugInfo] Prologue inserter need to insert DW_OP_deref_size

[Paul Robinson via Phabricator via llvm-commits]

probinson added inline comments.


================
Comment at: test/CodeGen/X86/prologepilog_deref_size.mir:58
+# CHECK: machineFunctionInfo
+# CHECK: DIExpression(DW_OP_plus_uconst, {{[0-9]+}}, DW_OP_deref_size, 2, DW_OP_LLVM_convert, 16, DW_ATE_unsigned, DW_OP_LLVM_convert, 32, DW_ATE_unsigned, DW_OP_stack_value)
----------------
Not sure I follow the purpose of these conversions. DW_OP_deref_size is specified to zero-extend the fetched bytes to the size of an address. The convert operators look like they are just doing the same thing over again?
