+; This bug was encountered in Ender Lilies, when an enemy attacked the player character there was a chance for a black screen flash.
+; This was due to a bug in FEX's `ZextAndMaskingElimination` pass which tries to remove useless vmov IR operations.
+; It incorrectly removed vmov IR operations that were explicitly zero extending vectors.
+; This vmov IR operation was generated by the movq instruction because the upper bits must be zero.
+; When vmov was removed, it would no longer zero the upper 64-bits, which left data in the register.
+; This results in a bad calculation.
