I suppose it's a lot easier to address the compilation speed

LLVM has about 2.5 million code lines. I am anything than sure
if it is easy to improve compilation speed.

Sorry for being off topic,
Rustc(uses LLVM) has a parallel codegen compilation mode that
decreases optimization for a (major AFAIK?) decrease in
compilation time when compiling multiple files. Would it be
possible for LDC to offer the same thing without a major
rewrite? I'm unfamiliar with the LDC codebase which is why I
ask.
Probably worth noting that even with parallel codegen rustc is
still far slower than ldc.

From time to time I dream about compiling modules in parallel. :-)
This needs some investigation but I think it could be possible to
spawn a thread per module you are compiling (after the frontend
passes). Never digged deeper into this...
