garbage collection of unused code

[Da Zheng]

Hello,

gc-selections in ld can enable garbage collection of unused input sections. I
hope some functions can be preserved even though they are not called by other
parts of the code. I don't want to change the code. Could I somehow specify in
the command line so that some specific functions are excluded from ld's garbage
collection?

I hope I can ask this question in this mailing-list.

Best regards,
Zheng Da
