[LLVMdev] Need to create symbols only once
Thanks for the reply Nick. I will use the Writer::addFiles functionality. Do you want to move the SimpleFile class to lld/Core ? It might be useful for other types of object files too(like for ELF here). How does typeFirstInSection/typeLastinSection know that the addresses that need to be used for those symbols are the symbol values for the section start / section end ? I didnt see references to typeFirstInSection/typeLastInSection in the MachO part of lld too, any pointers to how you are doing that will be helpful. If...

...ols), the writer returns a File object akin to a static library. That it, it provides no initial atoms, but can provide atoms as a last resort (so an .o files would override it). The WriterMachO already uses the addFiles() method to add CRuntime symbols. 2) DefinedAtom::ContentType already has typeFirstInSection and typeLastInSection. These are intended to be used for the content type of the atoms which represent the magic symbols for the start and end of a section. The key here is that the Pass (not written yet) which sorts atoms, knows to sort these atoms to the start or end of their respective section...

[LLVMdev] Need to create symbols only once
Hi Nick, We have few symbols like __bss_start, __bss_end, which are Undefined symbols in the code. I want a way in the Reader to create specific atoms before the linker bootstraps. I didnt find a way to do that with the existing interfaces. The way it needs to work is as below :- 1) ReaderELF creates Absolute symbols (for __bss_start, __bss_end etc) 2) ReaderELF reads each file and adds
