; If stack is realigned, we shouldn't describe locations of local
; variables by giving offset from the frame pointer (%rbp):
; push %rpb
; mov  %rsp,%rbp
; and  ALIGNMENT,%rsp ; (%rsp and %rbp are different now)
; It's better to use offset from %rsp instead.

; DW_AT_location of variable "x" shouldn't be equal to
; (DW_OP_fbreg: .*): DW_OP_fbreg has code 0x91

; CHECK: {{0x.* DW_TAG_variable}}
; CHECK-NOT: {{DW_AT_location.*DW_FORM_block1.*0x.*91}}
