My test.c
int main(int argc, char *argv[]) { char buffer[21] = {0}; int i; int *null = 0; read(0, buffer, 20); if (buffer[0]=='5'){ printf("==5\n"); } if(!memcmp(buffer,"7aaa",4)){ printf("==7aaa\n"); } }
My test_driller.py
import driller d = driller.Driller("./test", b"6") print(d.drill())
when input_str is b'6',I can get result b'7aaa',as predicted.
and the constraints were :
[<Bool file_0_stdin_0_7_160{UNINITIALIZED}[7:0] != 53>, <Bool file_0_stdin_0_7_160{UNINITIALIZED}[7:0] .. file_0_stdin_0_7_160{UNINITIALIZED}[15:8] .. file_0_stdin_0_7_160{UNINITIALIZED}[23:16] .. file_0_stdin_0_7_160{UNINITIALIZED}[31:24] == 0x37616161>]
But,when input_str is b'5',I can get nothing.
[<Bool file_0_stdin_0_7_160{UNINITIALIZED}[7:0] == 53>, <Bool file_0_stdin_0_7_160{UNINITIALIZED}[7:0] .. file_0_stdin_0_7_160{UNINITIALIZED}[15:8] .. file_0_stdin_0_7_160{UNINITIALIZED}[23:16] .. file_0_stdin_0_7_160{UNINITIALIZED}[31:24] == 0x37616161>]
Obviously, this constaints were unsolvable.
I think the first constraint:<Bool file_0_stdin_0_7_160{UNINITIALIZED}[7:0] == 53> should not appear here. How can i fix it? Thanks
