Hi Kirill, Uros I'm not sure if I was right to choose this maillist. We have a problem, the pta.flags structure is full. > #define PTA_SGX (HOST_WIDE_INT_1 << 63) How should I properly address this issue? Is the better solution to just create second flags variable, like with isa_flags and isa_flags2? Or better to try to use some custom type? There is an already existing double_int type in gcc, but I'm not sure if it will work properly in this case(at least in isa flags case there are problems). Thanks, Julia
