From email exchange:

I noticed that the “Offline Assembler” build step was taking between 5 and 30 seconds every time I build. Really stands out in incremental builds. I realized that this step does not do any dependency analysis. Every time, it builds a hash of the input to see if it needs to recompute the assembly.
