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.
