By the way gcc-4.8 will have support for -gsplit-dwarf, should be |
| 25 |
something similar to split-debug, just done pre linking and with |
| 26 |
different file names. |
| 27 |
While I've no idea how this feature work, probably start planning would |
| 28 |
be beneficial. |
| 29 |
|
| 30 |
-gsplit-dwarf |
| 31 |
Separate as much dwarf debugging information as possible into a |
| 32 |
separate output file with the extension .dwo. |
| 33 |
This option allows the build system to avoid linking files with |
| 34 |
debug information. |
| 35 |
To be useful, this option requires a debugger capable of reading |
| 36 |
.dwo files. |
| 37 |
|
| 38 |
|
| 39 |
|
| 40 |
Also thinking about this a bit more, seem a binpkg for debug stuff can |
| 41 |
be interesting, similarly to how binary distro do. |
| 42 |
rogue example implementation: |
| 43 |
with FEATURE="buildpkg split-debug-pkg" |
| 44 |
all the /usr/lib/debug and /usr/src/debug files are put in a separate |
| 45 |
package debug/category/pn or similarly to sec-policy/selinux* debug/cat--pn |
| 46 |
the user can then install debug packages at will, the dependancies |
| 47 |
should work (and clone those of the real package) but not be mandatory. |
| 48 |
|
| 49 |
how difficult would be to implement this in portage (keep in mind that |
| 50 |
packages are coupled and should stay that way also for unmerge and |
| 51 |
whatever)? |
| 52 |
Would be possible to have FEATURE=" -buildpkg split-debug-pkg"? |
| 53 |
|
| 54 |
A similar feature would be useful for linguas support but more difficult |
| 55 |
to implement. |
