## Test that we can correctly complete types even if the debug_names index ## contains entries referring to declaration dies (clang emitted entries like ## that until bd5c6367bd7). ## ## This test consists of two compile units and one type unit. CU1 has the ## definition of a variable, but only a forward-declaration of its type. When ## attempting to find a definition, the debug_names lookup will return the DIE ## in CU0, which is also a forward-declaration (with a reference to a type ## unit). LLDB needs to find the definition of the type within the type unit. # RUN: llvm-mc -triple=x86_64-pc-linux -filetype=obj %s > %t # RUN: %lldb %t -o "target variable s" -o exit | FileCheck %s # CHECK: (lldb) target variable s # CHECK-NEXT: (Struct) s = (member = 47) .data .p2align 2, 0x0 .long 0 s: .long 47 # 0x2f .section .debug_abbrev,"",@progbits .byte 1 # Abbreviation Code .byte 65 # DW_TAG_type_unit .byte 1 # DW_CHILDREN_yes .byte 19 # DW_AT_language .byte 5 # DW_FORM_data2 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 2 # Abbreviation Code .byte 19 # DW_TAG_structure_type .byte 1 # DW_CHILDREN_yes .byte 54 # DW_AT_calling_convention .byte 11 # DW_FORM_data1 .byte 3 # DW_AT_name .byte 14 # DW_FORM_strp .byte 11 # DW_AT_byte_size .byte 11 # DW_FORM_data1 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 3 # Abbreviation Code .byte 13 # DW_TAG_member .byte 0 # DW_CHILDREN_no .byte 3 # DW_AT_name .byte 14 # DW_FORM_strp .byte 73 # DW_AT_type .byte 19 # DW_FORM_ref4 .byte 56 # DW_AT_data_member_location .byte 11 # DW_FORM_data1 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 4 # Abbreviation Code .byte 36 # DW_TAG_base_type .byte 0 # DW_CHILDREN_no .byte 3 # DW_AT_name .byte 14 # DW_FORM_strp .byte 62 # DW_AT_encoding .byte 11 # DW_FORM_data1 .byte 11 # DW_AT_byte_size .byte 11 # DW_FORM_data1 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 5 # Abbreviation Code .byte 17 # DW_TAG_compile_unit .byte 1 # DW_CHILDREN_yes .byte 37 # DW_AT_producer .byte 8 # DW_FORM_string .byte 19 # DW_AT_language .byte 5 # DW_FORM_data2 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 6 # Abbreviation Code .byte 52 # DW_TAG_variable .byte 0 # DW_CHILDREN_no .byte 3 # DW_AT_name .byte 14 # DW_FORM_strp .byte 73 # DW_AT_type .byte 19 # DW_FORM_ref4 .byte 2 # DW_AT_location .byte 24 # DW_FORM_exprloc .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 7 # Abbreviation Code .byte 19 # DW_TAG_structure_type .byte 0 # DW_CHILDREN_no .byte 60 # DW_AT_declaration .byte 25 # DW_FORM_flag_present .byte 105 # DW_AT_signature .byte 32 # DW_FORM_ref_sig8 .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 8 # Abbreviation Code .byte 19 # DW_TAG_structure_type .byte 0 # DW_CHILDREN_no .byte 3 # DW_AT_name .byte 14 # DW_FORM_strp .byte 60 # DW_AT_declaration .byte 25 # DW_FORM_flag_present .byte 0 # EOM(1) .byte 0 # EOM(2) .byte 0 # EOM(3) .section .debug_info,"",@progbits .Ltu_begin0: .long .Ldebug_info_end0-.Ldebug_info_start0 # Length of Unit .Ldebug_info_start0: .short 5 # DWARF version number .byte 2 # DWARF Unit Type .byte 8 # Address Size (in bytes) .long .debug_abbrev # Offset Into Abbrev.
