|
information size. A major contribution to debug information size
|
| 63 |
|
|
is struct descriptions replicated in several object files. The
|
| 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. */
