Hello LLVM admins, I'm jinmoo seok, live in seout, Korea.

i have some problem about debug symbol. i want to how to solve this problem, so i email you.

source code is : #include int main() { std::cout << "hello world" << std::endl; return 0; }

this is simple source. but when i build it width debug symbol using clang, binary size is 100kb. when using gcc, binary size is 19kb

i tryed "readelf -wi " readelf: dwarf_loclist_form_expr_b: Invalid argument [dwarf_loclist_from_expr_b(279)] <237> DW_AT_data_member_location: 0 byte block: () <4><23a>: Abbrev Number: 9 (DW_TAG_member) <23b> DW_AT_name : (indirect string) _precision <23f> DW_AT_type : <0x799> <243> DW_AT_decl_file : 2 <244> DW_AT_decl_line : 363this message is repeatedly output. what does message mean?

and i tryed "readelf -s "
