[PATCH] D89795: [jitlink][ELF] Add zero-fill blocks for symbols in section SHN_COMMON

[Stefan Gränitz via Phabricator via llvm-commits]

sgraenitz added a comment.

The ELF spec has an extra paragraph for special handling in dynamic linkers. I am not sure how much it's relevant here:

  When the dynamic linker encounters a reference to a symbol that resolves to a definition of type STT_COMMON, it may (but is not required to) change its symbol resolution rules as follows: instead of binding the reference to the first symbol found with the given name, the dynamic linker searches for the first symbol with that name with type other than STT_COMMON. If no such symbol is found, it looks for the STT_COMMON definition of that name that has the largest size. 

What do you think?
