Greetings,
I've been redirected here from binutils:
http://sourceware.org/ml/binutils/2013-08/msg00052.html
http://sourceware.org/ml/binutils/2013-08/msg00056.html
The following source:
template<typename T> static void f();
void g() { f<int>(); }
results in "_Z1fIiEvv" under g++, but in "_ZL1fIiEvv" under clang.
Richard Smith says:
The ABI doesn't cover manglings for local symbols ...
... and c++filt is not able to cope with the L prefix here.
I'm having a hard time seeing how this isn't a g++ bug and a matching
c++filt bug.
It's hard for me to argue that this is a 'g++' bug (since there is no
ABI violation here), but c++filt should be able to handle this, and does
with attached patch.
Ok for trunk?
Thanks,
Google ref: b/10137049
