- Fixed name mangling conditions to handle 'linkonce' linkage type. In
...
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision. See comments in
CWriter::getValueName for more information.
- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.
- Fixed typos.
