Shameless plug: https://twitter.com/modocache/status/993515571928027137

The prior article in this series explained how the Swift and Clang compilers used llvm::SourceMgr to emit diagnostics for source locations in memory buffers, represented by the class llvm::MemoryBuffer. This article focuses on llvm::MemoryBuffer, the primary abstraction for reading files and streams into memory. Since it's used by Swift, Clang, and LLVM tools like llvm-tblgen, I found it valuable to understand how it works.

@slava_pestov My preference is realtime (more frequent merges mean less painful ones!), but we also have to track http://llvm.org master, which makes that impossible. When Swift drops its llvm/clang/cmark/lldb forks, that will become possible.

Just an FYI @jessesquires & @jpsim — I've been having some difficulties giving a useful short intro / overview of the Swift Unwrapped episodes (other than just mentioning the title of the episode); I would appreciate it if you could check these / contribute directly :)

[jessesquires]

@BasThomas will do!
