| 1009 | For the formats which don't provide fundamental types, gdb can create |

| 1012 | |
| 1013 | NOTE: This routine is obsolescent. Each debugging format reader |
| 1014 | should manage it's own fundamental types, either creating them from |
| 1015 | suitable defaults or reading them from the debugging information, |
| 1016 | whichever is appropriate. The DWARF reader has already been |
| 1017 | fixed to do this. Once the other readers are fixed, this routine |
| 1018 | will go away. Also note that fundamental types should be managed |
| 1019 | on a compilation unit basis in a multi-language environment, not |
