jankratochvil added a comment. The difference (with the previous size-non-setting patch) is:
-lldb < 14> send packet: $Z0,102f0,2# +lldb < 14> send packet: $Z0,102f0,4# That is because `GetAddressClass` fails to recognized `0x102f0` as a code address: PASS: (lldb) p (void)sync() GetAddressClass:0x102f1 GetAddressClass:0x102f1=(null) ValueIsAddress=1 section_type=1 GetAddressClass:0x96040 GetAddressClass:0x96040=__mmap ValueIsAddress=1 section_type=1 GetAddressClass:0x102f1 GetAddressClass:0x102f1=(null) ValueIsAddress=1 section_type=1 GetAddressClass:0x102f0 GetAddressClass:0x102f0=(null) ValueIsAddress=1 section_type=1 ... FAIL: (lldb) p (void)sync() GetAddressClass:0x102f1 GetAddressClass:0x102f1=_start ValueIsAddress=1 section_type=1 GetAddressClass:0x96040 GetAddressClass:0x96040=__mmap ValueIsAddress=1 section_type=1 GetAddressClass:0x102f1 GetAddressClass:0x102f1=_start ValueIsAddress=1 section_type=1 GetAddressClass:0x102f0 ... That is due to: symtab.fail:[ 11] 12 Invalid 0x00000000000102f0 0x0000000000000000 0x00000003 symtab.fail:[ 66] 99 X Code 0x00000000000102f0 0x0000000000000030 0x00000012 _start symtab.pass:[ 11] 12 Invalid 0x00000000000102f0 0x0000000000000030 0x00000003 symtab.pass:[ 66] 99 X Code 0x00000000000102f0 0x0000000000000030 0x00000012 _start The difference is in the 'Invalid' symbol which is: Num: Value Size Type Bind Vis Ndx Name 12: 000102f0 0 SECTION LOCAL DEFAULT 12 Apparently ARM32 relies on that section symbol to have proper size. I do not see how `Symtab::InitAddressIndexes` could handle `STT_SECTION` in a special way as that is ELF-type specific `Symbol` characteristics: uint32_t m_flags; // A copy of the flags from the original symbol table, the // ObjectFile plug-in can interpret these I did not debug it more as I think LLDB should have the symbol binding type preference anyway and then this problem disappears and we can keep status quo of this symbols size issue.
