Re: Restrictions on (object file/shareable image) symbol name
"
I dare say that you are correct about the lowest common denominator but a limit of 31 is not enough for languages that support overloading and use name mangling, unless those languages contain special hacks to account for the low limit, and I suspect strongly that the limit is higher on Itanium.
"
For C and C++, the limit is 31. Name mangling algorithm takes it into account, see below.
