A major contribution to debug information size 61 is struct descriptions replicated in several object files. The 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. 66 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. 75 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. 80 81 The remaining types of files are library headers and application 82 headers.
