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. */
