Since binutils/gdb can compress the .debug* sections with zlib into |
| 2 |
.zdebug*, we should be able to save quite a bit of space -- on my |
| 3 |
system, I saw /usr/lib/debug/ go from ~20GB to ~7.5GB. |
| 4 |
|
| 5 |
This requires binutils/gdb to be built with USE=zlib which is why |
| 6 |
this defaults to off. |
