| idea is to not emit struct debugging information in the current |
| compilation unit when that information will be generated by |
| another compilation unit. |
| |
| Debug information for a struct defined in the current source |
| file should be generated in the object file. Likewise the |
| debug information for a struct defined in a header should be |
| generated in the object file of the corresponding source file. |
| Both of these case are handled when the base name of the file of |
| the struct definition matches the base name of the source file |
| of the current compilation unit. This matching emits minimal |
| struct debugging information. |
| |
| The base file name matching rule above will fail to emit debug |
| information for structs defined in system headers. So a second |
| category of files includes system headers in addition to files |
| with matching bases. |
| |
| The remaining types of files are library headers and application |
