From 4001d90ddecdfc0e89daa4eca17006e20ad626c0 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Mon, 8 Feb 2021 15:18:12 +0100 Subject: [PATCH] [gdb/testsuite] Use DW_FORM_ref_addr in gdb.dwarf2/enqueued-cu-base-addr.exp When running test-case gdb.dwarf2/enqueued-cu-base-addr.exp with target board cc-with-dwz, I get: ... gdb compile failed, dwz: enqueued-cu-base-addr: \ Couldn't find DIE at [100] referenced by DW_AT_type from DIE at [d8] ... At 0xd8 we have DIE: ... <1>: Abbrev Number: 3 (DW_TAG_variable) DW_AT_name : foo
DW_AT_type : <0x100> DW_AT_const_value : 1 ... referring to: ... <1><100>: Abbrev Number: 3 (DW_TAG_base_type) <101> DW_AT_byte_size : 4 <102> DW_AT_encoding : 5 (signed) <103> DW_AT_name : int ... The reference is inter-CU, but the used abbrev uses DW_FORM_ref4: ... 3 DW_TAG_variable [no children] DW_AT_name DW_FORM_string DW_AT_type DW_FORM_ref4 DW_AT_const_value DW_FORM_sdata DW_AT value: 0 DW_FORM value: 0 ... which is for intra-CU references. Fix this by using a '%' instead of a ':' label prefix in the dwarf assembly.
