If you want to get the original name by a library function, as Jonathan<br>
mentioned, you can call __cxa_demangle in cxxabi.h. However, this API is<br>
only available in gcc.<br>

Huh? It's defined in the C++ ABI standard: <a href="http://mentorembedded.github.io/cxx-abi/abi.html#demangler" target="_blank">http://mentorembedded.github.<u></u>io/cxx-abi/abi.html#demangler</a><br>
<br>
There are implementations in libstdc++, libcxxabi and libcxxrt.<span class=""><br>
<br>
If you want something more portable, try glog or<br>

When a C++ compiler translates source code it will perform name<br>
mangling to avoid name collisions due to type overloading. You can<br>
use a tool like c++filt to de-mangle the generated names<br>

Hi, everyone!<br>
I'm new here trapped by a simple problem for days.<br>
When LLVM translates C++ source code to IR, it will add a<br>
prefix to<br>
the function name. For example:<br>
source code:<br>
int foo(){<br>
return 1;<br>
}<br>
IR form:<br>
define i32 @_Z3foov() #0 {<br>
entry:<br>
ret i32 1, !dbg !20<br>
}<br>
The getName() method returns _Z3foov, then how can I get<br>
foo? I<br>
know the debugging information is contained in metadata, but I've no<br>
idea on using it.<br>
Thanks a lot for any help.<br>
<br>
<br>
