[PATCH] D93497: Salvage debug info for function arguments in coro-split funclets.

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

Thanks, I can reproduce the the issue! However, it looks like it reproduces even without my patch. The frontend (or perhaps CoroSplit?) apparently insert both a "t" function argument and a "t"  local variable in the same scope:

  (lldb) b CoroCloner::create()
  (lldb) r
  (lldb) p OrigF.getParent()->dump();
  ...
  !1957 = !DILocalVariable(name: "t", arg: 2, scope: !1948, file: !883, line: 30, type: !1954)
  ...
  !1965 = !DILocalVariable(name: "t", scope: !1948, type: !1954, flags: DIFlagArtificial)

It's seems just that with my patch both variables survive and show up in DWARF.
