The attached file.cpp has these lines ...
class Foo
{
public:
std::initializer_list<int> list;
};
extern "C" void foo()
{
Foo f;
f.list = {1, 2, 3};
}
These commands use the tiarmclang compiler to demonstrate how to rename the function foo to new_foo in file.o. It works as expected.
$ tiarmclang -c file.cpp $ tiarmnm -g file.o 00000000 W _ZN3FooC2Ev 00000000 W _ZNSt16initializer_listIiEC2B6v15007Ev 00000000 T foo 00000000 T main $ tiarmobjcopy --redefine-sym=foo=new_foo file.o $ tiarmnm -g file.o 00000000 W _ZN3FooC2Ev 00000000 W _ZNSt16initializer_listIiEC2B6v15007Ev 00000000 T main 00000000 T new_foo
Try to do the same thing with the TI proprietary Arm compiler.

The armobjcopy command fails.
