Description
Main issue:
https://github.com/llvm/llvm-project/issues/169959
7. Comparison with impossible value. The PVS-Studio warnings: V560 a part of conditional expression is always false: Opc == ARM::MVE_VORR. ARMBaseInstrInfo.cpp 752
Contributor guide
Research direction
Read LLVM issue 169959 and inspect ARMBaseInstrInfo.cpp around line 752, focusing on the conditional containing ARM::MVE_VORR. Determine why the static analyzer reports that comparison as impossible and identify the intended handling. Done means the warning is resolved without changing valid ARM instruction behavior.
