--- Comment #2 from Renlin Li <renlin.li at arm dot com> --- VEC_COND_EXPR with V2DI mode is generated as aarch64 target supports it (vcond<mode><mode>). The VEC_COND_EXPR expression will further folded into MIN_EXPR/MAX_EXPR expression in the dom pass. However, aarch64 min/max expanders don't support V2DI mode. The compiler tries to generate compare and jump sequence for this, and no vector compare can be found(aarch64 dose have one, however, the compiler uses cbranch as a key to search for a compare insn). And no library function is provided, it asserts.
