bfin-dis.c:160 shift exponent 32 is too large for 32-bit type 'long unsigned int'
bpf-ibld.c:196 left shift of 1 by 31 places cannot be represented in type 'long int'
bpf-ibld.c:196 negation of -2147483648 cannot be represented in type 'long int'; cast to an unsigned type to negate this
 itself
bpf-ibld.c:197 left shift of 1 by 31 places cannot be represented in type 'long int'
bpf-ibld.c:197 signed integer overflow: -2147483648 - 1 cannot be represented in type 'long int'
bpf-ibld.c:501 left shift of 1 by 31 places cannot be represented in type 'long int'
