Assembly Code Question:

This is At&t assembly I'm pretty sure. If this code runs from its start until the endpoint, the value in register edx will be:

0x40106e : mov $0x1,%edx 0x401073 : mov $0x8,%ecx 0x401078 : test %ecx,%ecx 0x40107a : jg 0x40107e  0x40107c : jmp 0x40108a  0x40107e : lea (%ecx,%ecx,1),%eax 0x401081 : lea (%eax,%edx,1),%eax 0x401084 : lea 0xffffffff(%eax),%edx 0x401087 : dec %ecx 0x401088 : jmp 0x401078  0x40108a : // endpoint

I'm having a hard time figure out the answer to this question. I mainly don't understand the line that says "lea 0xffffffff(%eax),%edx" what exactly is this doing?
