A major contribution to debug information size is struct descriptions replicated in several object files. The following flags attempt to reduce this information. The basic 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 headers. We cannot currently distinguish these two types. */ enum debug_struct_file { DINFO_STRUCT_FILE_NONE, /* Debug no structs. */ DINFO_STRUCT_FILE_BASE, /* Debug structs defined in files with the same base name as the compilation unit. */ DINFO_STRUCT_FILE_SYS, /* Also debug structs defined in system header files. */ DINFO_STRUCT_FILE_ANY /* Debug structs defined in all files. */ }; /* Enumerate visibility settings.
