[PATCH] D117853: [ELF] Parallelize --compress-debug-sections=zlib

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: lld/ELF/OutputSections.cpp:345
   // Write section contents to a temporary buffer and compress it.
   std::vector<uint8_t> buf(size);
   writeTo<ELFT>(buf.data());
----------------
This zero fills the buffer, but I have tested that removing it and adding gap filling in `writeTo` does not improve performance.
