[LLVMdev] [lld] supporting gnu linkonce sections in core linking
...as used in a
way to model COMDAT in early ELF implementations.
We have seen usecases of .gnu.linkonce sections used in various object
files(mainly libc), and I think its much needed to support this style in
lld as well.
_*a solution to support .gnu.linkonce in lld*_
I was thinking of adding a typeGnuLinkOnce and special case it in the
Resolver.
_*Differences between .gnu.linkonce and COMDAT*_
The only thing that I see a difference between gnu linkonce sections and
COMDAT is to raise an error when there is a similar looking section with
section groups.
Do you see any better design solutions here ?...
