Created attachment 248702 [details] Linux executable. Hi Eugene, Using attached zip file, step to p.adb:10. Open expression view and add tp The expression view displays: Name Type Value tp pack__tp_access 0x8a0d010 The property show a size of 4. I would have expected, since tp is pointer to an array, to be able to unfold tp and see the various array elements. If I dump memory at 0x8a0d010, I see a correct content. Looking at the dwarf-infos: <2><8d8>: Abbrev Number: 12 (DW_TAG_variable) <8d9> DW_AT_name : tp <8dc> DW_AT_decl_file : 1 <8dd> DW_AT_decl_line : 5 <8de> DW_AT_type : <0x850> <8e2> DW_AT_location : 2 byte block: 91 6c (DW_OP_fbreg: -20) <1><850>: Abbrev Number: 5 (DW_TAG_typedef) <851> DW_AT_name : (indirect string, offset: 0xa52): pack__tp_access <855> DW_AT_decl_file : 2 <856> DW_AT_decl_line : 8 <857> DW_AT_type : <0x85b> <1><85b>: Abbrev Number: 6 (DW_TAG_pointer_type) <85c> DW_AT_byte_size : 4 ==> Size correctly retrieved. <85d> DW_AT_name : (indirect string, offset: 0xa52): pack__tp_access <861> DW_AT_type : <0x865> <1><865>: Abbrev Number: 7 (DW_TAG_array_type) <866> DW_AT_name : (indirect string, offset: 0xb7c): pack__s <86a> DW_AT_type : <0x825> <86e> DW_AT_sibling : <0x88c> <2><872>: Abbrev Number: 4 (DW_TAG_subrange_type) <873> DW_AT_type : <0x81e> The dwarf looks OK to me, I can't figure out why the IDE doesn't allow to "unfold" tp. Rather than returning <850> as type, shouldn't <865> be returned ? Moreover, I have an agent crash if I try to cast: (pack__s *) 0x8a0d010 Server-Properties: {"Name":"TCF Agent","OSName":"Linux 3.2.0-70-generic","UserName":"xavier","AgentID":"1460db33-74db-46a4-80e3-24007a71e292","TransportName":"TCP","ServiceManagerID":"1460db33-74db-46a4-80e3-24007a71e292-0","Port":"1534"} agent: tcf/services/symbols_elf.c:3924: elf_reader_get_array_symbol: Assertion `sym->ctx == context_get_group(sym->ctx, 6)' failed. Aborted (core dumped) Thanks ! Xavier.
More than one issue here: 1. DWARF info appears invalid: <2><872>: Abbrev Number: 4 (DW_TAG_subrange_type) <873> DW_AT_type : <0x81e> <877> DW_AT_lower_bound : 8 byte block: 97 23 f8 ff ff ff f 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 4294967288; DW_OP_deref) <880> DW_AT_upper_bound : 10 byte block: 97 23 f8 ff ff ff f 23 4 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 4294967288; DW_OP_plus_uconst: 4; DW_OP_deref) "DW_OP_plus_uconst: 4294967288" cannot be right. 2. I've committed a fix for assertion failure. 3. To support type cast to a pointer to variable array (e.g. "(pack__s *)0x8a0d010"), I need to change declaration of get_array_symbol() function. This is not a backward compatible change - if you use symbols multiplexer, it will break your build. Let me know if you are OK with that.
Hi Eugene, Thanks ! > *)0x8a0d010"), I need to change declaration of get_array_symbol() function. This is not a backward compatible change - if you use symbols multiplexer, it will break your build. Let me know if you are OK with that. OK : We'll fix the symbols multiplexer then. Thanks ! Xavier.
