Hi Guys,
I apologise - I know that Jose CC'ed me on this topic, but I have lost
the email, so I am creating this post instead.
What about using an OS-specific section flag in elf.h, something like:
#define SHF_GNU_PERSISTENT 0x0ff00001 /* Section must not be stripped. */
I rather like this idea. It would certainly make things easier.
Assuming that is that there is a convenient way to set the flag. Ie
we need to teach the assembler about it, and probably the linker too
(so that it can be used in linker scripts).
It might also be a nice idea to have a complimentary flag to indicate
sections that expect to be stripped, even if they might otherwise be
retained. For example:
#define SHF_GNU_TREAT_AS_DEBUG 0x0ff00002 /* Treat as a debug info section. Strip with other debug sections and move to a separate debug info file when creating such
files. */
This could be added to note sections for example, where the notes
will not be needed at run-time.
Cheers
Nick
