4; If stack is realigned, we shouldn't describe locations of local
5; variables by giving offset from the frame pointer (%rbp):
6; push %rpb
7; mov %rsp,%rbp
8; and ALIGNMENT,%rsp ; (%rsp and %rbp are different now)
9; It's better to use offset from %rsp instead.
10
11; DW_AT_location of variable "x" shouldn't be equal to
12; (DW_OP_fbreg: .*): DW_OP_fbreg has code 0x91
