[PATCH] D75326: [entry values] X86: Describe effects of MOV{8,16}ri (PR45053)

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

> 3.4.2. DW_AT_call_value attribute which is a DWARF expression which when evaluated yields the value of the parameter at the time of the call.

Curiously, DW_OP_piece is only described in chapter 2.6 Location descriptions and not in 2.5. DWARF Expressions. I *think* this may just be a bug in the spec. We should raise this question on dwarf-discuss for clarification, so we either learn why it is this way or can fix the spec to be less misleading.
