| /* From ARM C++ ABI \S 3.2.5.5: |
| |
| A class should be exported unless explicitly tagged otherwise. |
| |
| This admonition applies even on DLL-based systems where hidden |
| visibility is the default. We want -fvisibility=hidden to behave |
| identically to the situation where hidden visibility is the |
| hard-wired default. So, both A and B are exported classes. |
| |
| Furthermore: |
| |
| If CAG symbol Y names one of the impedimenta associated with an |
| exported class X: |
| |
| ... |
| |
| * Otherwise, if X has no key function: |
| |
| - Y is exported from ... each DLL that refers to X and uses Y. |
| |
| So, the type-info and virtual-table symbols associated with A and B |
| must be exported. */ |
