It seems like LLVM libunwind is designed to be compatible with the libgcc libunwind api, as suggested in [/libunwind/include/libunwind.h](https://github.com/llvm/llvm-project/blob/339f58de16ac7a31869d189bec6cad7696958546/libunwind/include/libunwind.h#L9):
```
// Compatible with libunwind API documented at:
// http://www.nongnu.org/libunwind/man/libunwind(3).html
```
However the definition of `unw_regname` is different between the two libraries.
LibGCC libunwind:
```
const char *unw_regname(unw_regnum_t);
```
LLVM libunwind:
```
const char *unw_regname(unw_cursor_t *, unw_regnum_t) LIBUNWIND_AVAIL;
```
Not sure if this is intentional?
