@ -14,7 +14,8 @@ the unwinder:
| Feature | Default | Description |
|--------------------- |---------|-|
| unwinder | Yes | The primary feature gate to enable the unwinder |
| fde-phdr | Yes | Use `dl_iterator_phdr` to retrieve frame unwind table. Depends on libc. |
| fde-phdr-dl | Yes | Use `dl_iterator_phdr` to retrieve frame unwind table. Depends on libc. |
| fde-phdr-aux | No | Use ELF auxiliary vector to retrieve frame unwind table. Depends on libc. |
| fde-registry | Yes | Provide `__register__frame` and others for dynamic registration. Requires either `libc` or `spin` for a mutex implementation. |
| fde-gnu-eh-frame-hdr | No | Use `__executable_start`, `__etext` and `__GNU_EH_FRAME_HDR` to retrieve frame unwind table. The former two symbols are usually provided by the linker, while the last one is provided if GNU LD is used and --eh-frame-hdr option is enabled. |
| fde-static | No | Use `__executable_start`, `__etext` and `__eh_frame` to retrieve frame unwind table. The former two symbols are usually provided by the linker, while the last one would need to be provided by the user via linker script. |
