## Testcase is based on output produced by gcc version 5.4.1 20160904
|
|
## it has duplicate entries in .debug_gnu_pubtypes which seems to be
|
|
## compiler bug. In that case it is useless to have them in .gdb_index
|
|
## and we filter such entries out to reduce size of .gdb_index.

## CHECK: Constant pool offset = {{.*}}, has 1 CU vectors:
|
|
## CHECK-NOT: 0(0x0): 0x90000000 0x90000000
