61 | /* A major contribution to object and executable size is debug |
62 | information size. A major contribution to debug information size | |
63 | is struct descriptions replicated in several object files. The | |
64 | following flags attempt to reduce this information. The basic | |
65 | idea is to not emit struct debugging information in the current | |
66 | compilation unit when that information will be generated by | |
67 | another compilation unit. | |
68 | ||
69 | Debug information for a struct defined in the current source | |
70 | file should be generated in the object file. Likewise the | |
71 | debug information for a struct defined in a header should be | |
72 | generated in the object file of the corresponding source file. | |
73 | Both of these case are handled when the base name of the file of | |
74 | the struct definition matches the base name of the source file | |
75 | of the current compilation unit. This matching emits minimal | |
76 | struct debugging information. | |
77 | ||
78 | The base file name matching rule above will fail to emit debug | |
79 | information for structs defined in system headers. So a second | |
80 | category of files includes system headers in addition to files | |
81 | with matching bases. | |
82 | ||
83 | The remaining types of files are library headers and application | |
84 | headers. We cannot currently distinguish these two types. */ | |
