[PATCH] D52634: [WIP] [WebAssembly] Add DBG_VALUE with local operands location in WebAssemblyExplicitLocals pass

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

Can you explain how this new operation is meant to work?



================
Comment at: include/llvm/BinaryFormat/Dwarf.def:626
+// Extensions for WebAssembly.
+HANDLE_DW_OP(0xF6, WASM_location, 0, WASM)
 // Extensions for Fission proposal.
----------------
`0xf6`
Did you check against https://sourceware.org/elfutils/DwarfExtensions to see if this is is available?


================
Comment at: include/llvm/BinaryFormat/Dwarf.h:62
+  DWARF_VENDOR_MIPS = 6,
+  DWARF_VENDOR_WASM = 7
 };
----------------
Is this actually WASM-specific or is LLVM the only implementation and you could use LLVM instead?
