[LLVMdev] How much memory clang llvm needs for debug compiling?

[Ronaldo Ferreira]

I have a 7 years old computer with 1 GB RAM and I was able to build clang
in debug mode. I created a swap file of 4 GB I think, and I've stopped
using the computer at all, just grab some tea and wait.

This link shows you how you can create a swap file:

At least for me it worked well.
