Based on cmake/modules/LLVMLibDeps.cmake, I produced a graphviz dot file and then manually removed components and edges until the graph was small enough to be presentable. I don't know if I can actually use LLVM due to its humongousness, but I hope the graph will be helpful to others attempting to comprehend LLVM. PNG attached; dot file follows. digraph G { ipo

Works for me. Presumably #including <cassert> will fix it though?

The driver behaves differently when I run it by specifying absolute path than when I run it with relative path.

Hi XCore and PIC16 maintainers, I'd appreciate it if you guys could move your AsmPrinter implementation to be in a subdirectory like the rest of the other targets (e.g. make it live in lib/Target/PIC16/AsmPrinter). Anton is planning to move MSP430 to use the same approach. Having all the targets use the same design simplifies the build system and keeps the target architecture more

Hi Roberto, The PIC24 family of devices share very little commonality with PIC16 beyond the naming convention. They're a register-based 16-bit architecture, unlike the PIC16. That said, that does mean that LLVM is a much more reasonable fit to target the PIC24 (and dsPIC) than it is for PIC16. Modeling your target files after the MSP430 or Blackfin backend is likely your best bet to get up
