/* A major contribution to object and executable size is debug

information size. 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. */
