I agree.

> Would this mean asm w/o unwind cannot unwind?

The unwind keyword causes llvm to treat the inline assembly as "unwindable", so appropriate unwind information/tables are emitted by codegen. By omitting the unwind keyword, llvm doesn't emit these information and therefore unwinding from inline assembly might not be sound or even UB.
