| 29 | // The CFA name mangling scheme is based closely on the itanium C++ name mangling scheme, with the following key differences: |
---|
| 30 | // * Variable names are also mangled to include type information, not just functions |
---|
| 31 | // * CFA does not have template expansion, so the rules for function specialization do not apply. |
---|
| 32 | // * CFA instead has to handle type parameters and assertion parameters. |
---|
| 33 | // * Currently name compression is not implemented. |
