Hi!
Looks like the code:
ALU_ARSH_X: DST = (u64) (u32) ((*(s32 *) &DST) >> SRC); CONT; ALU_ARSH_K: DST = (u64) (u32) ((*(s32 *) &DST) >> IMM); CONT;
works incorrectly on BE arches since it must operate on lower parts of 64bit registers.
See failure of test_verifier test 'arsh32 on imm 2' (#23 on 5.2-rc6).
