6; We're mostly checking that relocations are applied correctly
7; here. Currently R_AARCH64_ABS32 is used for references to debug data
8; and R_AARCH64_ABS64 is used for program addresses.

10; A couple of ABS32s, both at 0 and elsewhere, interpreted correctly:
11
12; CHECK: DW_AT_producer [DW_FORM_strp] ( .debug_str[0x00000000] = "clang version 3.3 ")
13; CHECK: DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000013] = "tmp.c")

15; A couple of ABS64s similarly:
16
17; CHECK: DW_AT_low_pc [DW_FORM_addr] (0x0000000000000000 ".text")
18; CHECK-4: DW_AT_high_pc [DW_FORM_data4] (0x00000008)
19; CHECK-3: DW_AT_high_pc [DW_FORM_addr] (0x0000000000000008 ".text")
