The Windows on ARM target uses custom division for normal division as the backend needs to insert division-by-zero checks. However, it is designed to only handle non-vectorized division. ARM has custom lowering for vectorized division as that can avoid loading registers with the values and invoke a division routine for each one, preferring to lower using NEON instructions. Fall back to the custom lowering for the NEON instructions if we encounter a vectorized division. Resolves PR31778! llvm-svn: 293259 |
