A previous argument against the LLVM versions of binutils replacements
is that they were excessively large, but this does not look like a
substantial problem here. LLVM's cxxfilt is indeed many times the size
of ELF Tool Chain's, but still small enough that for a tool chain
component it's not a concern, in my opinion.
ELF Tool Chain:
$ size obj/c++filt
text data bss dec hex filename
66966 1008 8400 76374 0x12a56 obj/c++filt
LLVM:
$ size obj/llvm-cxxfilt
text data bss dec hex filename
378138 1756 9165 389059 0x5efc3 obj/llvm-cxxfilt
A remaining issue is that both nm and addr2line can also demangle C++ symbols.
