62 following flags attempt to reduce this information. The basic
63 idea is to not emit struct debugging information in the current
64 compilation unit when that information will be generated by
65 another compilation unit.
67 Debug information for a struct defined in the current source
68 file should be generated in the object file. Likewise the
69 debug information for a struct defined in a header should be
70 generated in the object file of the corresponding source file.
71 Both of these case are handled when the base name of the file of
72 the struct definition matches the base name of the source file
73 of the current compilation unit. This matching emits minimal
74 struct debugging information.
76 The base file name matching rule above will fail to emit debug
77 information for structs defined in system headers. So a second
78 category of files includes system headers in addition to files
79 with matching bases.
81 The remaining types of files are library headers and application
