[PATCH] D87272: [lld] Buffer writes when composing a single diagnostic

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

(side note: raw_ostream already has buffering support - any idea why its performance is still significantly different than the extra layer of buffering on top of it? Might be a matter of enabling buffering in lld::errs() (lld::errs().SetBufferSize(N))? That'd still work with colored output without any troubles (it'd be flushed as needed on platforms where flushing is needed). I still think if there are use cases where the performance of errors matters to users - they probably should be addressed in other ways, though, such as being able to disable warnings the user isn't interested in)
