binary elf
addr2line and c++filt rely upon libiberty demangling
Could it be improved to handle _GLOBAL_ symbols?
$ c++filt _GLOBAL__sub_I__Z11print_tracev
_GLOBAL__sub_I__Z11print_tracev
$
$ c++filt _Z11print_tracev
print_trace()
$
$ c++filt --version
GNU c++filt (GNU Binutils for Ubuntu) 2.30
$ addr2line -f -C -e exception4 0x0000000000001600
_GLOBAL__sub_I__Z11print_tracev
/home/jonny/code/crash/exception4.cpp:100
Maybe the "_GOBAL_" prefix just needs to be stripped?
I had filed this before on binutils
