Subject: Question about debug symbol
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<iostream>
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 <binary>"
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 <binary>"
<address> 0 NOTYPE LOCAL DEFAULT 31
this message is output too many.
why debug_str size is too big?
i test both clang34 and clang38
clang38's binary size is nearly as twice as clang34's binary.
i wan't to why this problem happen.
My environment:
i386
freebsd11
