[PATCH] D75425: [docs] Added solutions to slow build under common problems

[Erich Keane via Phabricator via llvm-commits]

Anything like this without an LLD/Gold reference is likely insufficient.  In my experience, switching to Gold or LLD has been the biggest benefit so far.

That said, do we have a version of our build scripts that build LLD and use it from then on out?  We might find that despite increasing the build time a bit, it would improve compilation on low-resource machines.



================
Comment at: llvm/docs/GettingStarted.rst:1104
+ * -DCMAKE_BUILD_TYPE  
+   Set this equal to the build you wish to use, either Debug or Release. The 
+   Debug build may consume more memory during the linking phase.

While slightly less useful (since you can't as easily debug), a note about release-with-asserts as a good middle ground that compiles roughly as quickly as the normal release build might be valuable.
