Dear Maintainer,

I'm attaching a tarball that, when extracted in the home directory,
should demonstrate the issue.

Running perf report -g --demangle shows

None of bfd_demangle() from libbfd, cplus_demangle() from libiberty,
abi::__cxx_demangle() from libstdc++ are able to demangle this symbol. 
(We currently configure perf to use abi::__cxx_demangle.)

The llvm-cxxfilt command demangles it to "void
Botan::Cipher_Mode::update<std::vector<unsigned char,
Botan::secure_allocator<unsigned char>>>(std::vector<unsigned char,
Botan::secure_allocator<unsigned char>>&, unsigned long)" but it seems
to be ignoring part of the symbol, specifically 
"Botan::concepts::resizable_byte_buffer".

If I delete the "Tk" from the mangled symbol then they all agree it
should be demangled to "void
Botan::Cipher_Mode::update<std::vector<unsigned char,
Botan::secure_allocator<unsigned char>>>(std::vector<unsigned char,
Botan::secure_allocator<unsigned char>>&, unsigned long)".

What does the actual declaration of this function look like, and what
toolchain are you using to compile it?

I get this out of src:botan3 3.7.1+dfsg-2 src/lib/modes/cbc/cbc.cpp
when building with clang trunk (21.0.0 (++20250519112653+d0ee35851bb9-1~exp1~20250519112844.1459))
                               (from http://apt.llvm.org/bookworm/)
when configuring as ./configure.py --minimized-build --enable-modules cbc,twofish
then building with make build/obj/lib/modes_cbc.o

The construction looks like
  class secure_allocator { /* ... */ };
  using secure_vector = std::vector<T, secure_allocator<T>>;

  class BOTAN_PUBLIC_API(2, 0) Cipher_Mode : public SymmetricAlgorithm {
    template <concepts::resizable_byte_buffer T>
    void update(T& buffer, size_t offset = 0) {
      // ...
    }
  }
  
  class CBC_Mode : public Cipher_Mode {}
  class CBC_Encryption : public CBC_Mode {
  private:
  	void finish_msg(secure_vector<uint8_t>& final_block, size_t offset = 0) override;
  }
  
  void CBC_Encryption::finish_msg(secure_vector<uint8_t>& buffer, size_t offset) {
    // ...
  
    update(buffer, offset);
  }
(there's some other callers but they all use the same update overload).

So the full declaration will be something like
  template<concepts::resizable_byte_buffer = std::vector<unsigned char, Botan::secure_allocator<unsigned char>>>  // except as an instantiation, not a default
  void Botan::Cipher_Mode::update(std::vector<unsigned char, Botan::secure_allocator<unsigned char>>, unsigned long);
so llvm-cxxfilt gets it mostly right.

I don't really see why the concept bit is in there either,
it feels like it ought to be immaterial?

This must mean that's "The koncept" as an extension, then, clearly?
Maybe this wants to get forwarded to LLVM more-so than anything else.

Building with bookworm GCC doesn't give give me any symbols
matching /update/ except for an update_granularity.

You forwarded this to
<https://github.com/llvm/llvm-project/issues/147790> and the response
was that this extension was propsoed in
<https://github.com/itanium-cxx-abi/cxx-abi/issues/24> (opened in
2017!).

- The "Tk" sequence seems to be first mentioned by zygoloid on Mar 31,
2023

- g++ started generating this in 
<https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=c3f281a0c1ca50e4df5049923aa2f5d1c3c39ff6>
(September 2023)

- libiberty imported that change in 
<https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e2a26339456487e80344a8c3bd0f10711ff28567>
(January 2024)

So it seems like the GNU tools also use this sequence, but perhaps they
have diverged from LLVM on the precise syntax...
