Thank you, Ian. Yes, I want V4DImode and in the xx.md file I write match_operand:V4DI in this pattern. The type of int64x4_t is define in xx.h: typedef int64_t int64x4_t __attribute__((vector_size (32))); This type is OK in other builtin-funcs, only imm-operand-builtin-funcs get this error. So, I'm confused. --Liu
