[capstone2llvmir]: Arm64: extractVectorValue(): Unknown VESS type
It seems failed here
https://github.com/avast/retdec/blob/2cf18ffeb249bbe499d455eb67069bef0b072c9a/src/capstone2llvmir/arm64/arm64.cpp#L411
any idea how to solve it？

Research direction
Reproduce the failure with bin/retdec-decompiler ./lib_test.so and confirm the Arm64 diagnostic. Inspect src/capstone2llvmir/arm64/arm64.cpp at the linked line and trace extractVectorValue() to understand which VESS type reaches the error. Done means the reported input gets through LLVM IR decoding without this diagnostic.
