[LLVMdev] [lld] LLD's software architecture

[Bas van den Berg]

Hi,

I'm analysing the LLD code structure (aka architecture) and am
trying to mold it into a component model.
Currently I see 4 components:
- Driver
- ReaderWriter
- Passes
- Core

I wonder if this is the order that they're supposed to be in,
since there are also code dependencies upwards from:
  Core -> ReaderWriter
  Passes -> ReaderWriter
  ReaderWriter -> Driver

For a graphical view check:

I think that with a few surgical patches, the dependency tree
can be completely free of circular deps.
