[PATCH] D140338: [DWARF] Store CFA value on DW_CFA_remember_state

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

DWARF v5 says:

> The DW_CFA_remember_state instruction takes no operands. The required action is to push the set of rules for every register onto an implicit stack.

I think it probably should mention that "the current CFA rule" is saved as well.
