| 27 | // The CFA name mangling scheme is based closely on the itanium C++ name mangling scheme, with the following key differences:
|
|---|
| 28 | // * Variable names are also mangled to include type information, not just functions
|
|---|
| 29 | // * CFA does not have template expansion, so the rules for function specialization do not apply.
|
|---|
| 30 | // * CFA instead has to handle type parameters and assertion parameters.
|
|---|
| 31 | // * Currently name compression is not implemented.
