According to the Itanium ABI spec certain classes in the
std
namespace have their own abbreviations and do not start withSt
so the current check would not mark them asstd
functions. However, I am not sure if these abbreviations are actually used by the LLVM Itanium mangler. I haven't looked at the source code yet but I looked at the symbols of some test applications usingnm
and all mangled names ofstd::
functions started with_ZSt
,_ZNSt
or_ZNKSt
(this last one is forconst
member functions and was missing previously), so maybe it is enough to just check for these three.Opening this as a draft for now until I'm sure which is the correct approach (hoping that someone who knows more about this sees this and can comment on it).
