<pre>This program
#include <string>
int main() { std::string s; }
compiled with clang latest snapshot LLVM-3.6.0-r215932-win32.exe against
libstdc++ 4.9.1 and dumped with dwarf-dump produces a dump of 324 lines. When
compiled with gcc 4.9.1 the dump is 6879 lines. The commands to reproduce are:
"c:\Program Files (x86)\LLVM\bin\clang.exe" -c -g -O0 -gdwarf-4 a.cpp -target
i686-pc-windows-gnu
llvm-dwarfdump.exe a.o > a_clang.txt
gcc -c -g -O0 a.cpp
llvm-dwarfdump.exe a.o > a_gcc.txt
Most of the debug info is missing in the clang output, for example there are no
DW_TAG_members at all.
I tried various -g levels 0,1,2,3 with no change at all in the dump.
Maybe the -g debugging level logic is broken?</pre>
