================
Comment at: llvm/lib/MC/MCObjectFileInfo.cpp:1189
+ // SHF_WRITE for relocations, and let user post-process data in-place.
+ unsigned Flags = ELF::SHF_WRITE | ELF::SHF_ALLOC | ELF::SHF_LINK_ORDER;
+
----------------
Do we actually plan to write to these sections? Does setting SHF_WRITE prevent sharing of pages across multiple processes? Of SHF_WRITE pages still mapped as shared/write-protected first and then subject to copy-on-write?
