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.
