[PATCH] D42176: [WebAssembly] Optimise relocation iteration to remove n^2 loop. NFC.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

Hmm, I think I'm confused. IIUC, a wasm object file has single .data and .code section, and there is one relocation section for each section.

A "section" in wasm is actually not an atomic unit of inclusion/exclusion. It can be split into multiple "chunks", and "chunks"  is a unit of garbage collection.

But why does that two-level abstraction needed? Why can't everything just a section?
