; RUN: llc -filetype=obj -o - < %s | llvm-dwarfdump - --debug-loc | FileCheck %s

; Created using clang -g -O3 from:
; struct S0 {
; short f0;
; int f3;
; } a;
; void fn1(short p1) {
; struct S0 b, c = {3};
; b.f3 = p1;
; a = b = c;
; }
;
; int main() { return 0; }
;
; This is similar to the bug in test/DebugInfo/ARM/PR26163.ll, except that there is an
; extra non-overlapping range first. Thus, we make sure that the backend actually looks
; at all expressions when determining whether to merge ranges, not just the first one.
; AS in 26163, we expect two ranges (as opposed to one), the first one being zero sized
;
