Technical tradeoffs
- • Changes the return value of `vectype_to_qualifier` and `get_qualifier_from_partial_encoding` in error cases, which might affect code relying on the previous behavior.
- • Introduces a more explicit error signaling mechanism, potentially improving debugging and error handling.

[PATCH 19/23] aarch64: Return QLF_ERR for error conditions
This patch changes the functions vectype_to_qualifier and get_qualifier_from_partial_encoding to return AARCH64_OPND_QLF_ERR instead of AARCH64_OPND_QLF_NIL when an error condition is encountered. This makes error handling more explicit and consistent within the AArch64 assembly code, which helps catch errors earlier and could simplify debugging.
