Hi,
When a use kleaver to solve a query, I found that "Ult" and "Ugt" can not be used at the same time. the logic is simple: if( sn > 5) { if( sn < 8 ) { if (sn==0) printf("hello"); } } the query is as follows: ==================== array sn[4] : w32 -> w8 = symbolic (query [(Ult 5 N0:(ReadLSB w8 0 sn)) (Ugt N0 8) ] (Eq N0 0) [] [ sn ] ) ==================== it crashes the kleaver, but when I change the file to : ==================== array sn[4] : w32 -> w8 = symbolic (query [(Ult 5 N0:(ReadLSB w8 0 sn)) (Ult N0 8) ] (Eq N0 0) [] [ sn ] ) ========================= it works normal. could you tell me why ? What is different between "Ugt" and "Ult", or I have made some mistake when using kleaver? Thanks.
