[PATCH] D28083: Add an index for Module Metadata record in the bitcode

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added inline comments.


================
Comment at: llvm/lib/Bitcode/Writer/BitcodeWriter.cpp:1921
+  // patched when we emit the index later. We can simply subtract the 64-bit
+  // fixed size from the current bit number to get the location to backpatch.
+  uint64_t BeginBlockBitPos = Stream.GetCurrentBitNo();
----------------
The 64 is documented here, do you thinks it is worth repeating the comment below?
