[libcxx-commits] [PATCH] D110731: [libunwind] Fix cfi_register for float registers.

[Daniel Kiss via Phabricator via libcxx-commits]

danielkiss added a comment.

As I know `.cfi_undefined` is not emitted and `.cfi_register` is emitted for general purpose registers only, while both appear in hand written assembly for floating point registers on aarch64.
It is possible to write assembly code that misses this support on arm with dwarf.
