[LLVMdev] How to add a trivial LLVM intrinsic

[Matt Renzelmann]

Thank you again for your help.  Assuming my experimental "noop" intrinsic is
intended to be target independent, what file should I modify to provide the
code generator with the necessary information?  I've already modified:

./lib/CodeGen/IntrinsicLowering.cpp
./lib/Target/CBackend/CBackend.cpp
./include/llvm/Intrinsics.td

Presumably it's not one of those?  Or, if it is, I imagine I've simply
screwed something up?

Thanks again,
Matt

that's because you didn't tell the code generators what
they should do with your intrinsic.

Ciao,

Duncan.
