[LLVMdev] How to add a trivial LLVM intrinsic

[Matt Renzelmann]

Thank you for your reply--I've now done that.  Unfortunately, there's a new
error now:

------------
Cannot yet select: intrinsic %llvm.test_intrinsic
test.c:25: internal compiler error: Aborted
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://developer.apple.com/bugreporter> for instructions.
------------

I've switched to using LLVM-2.5 instead of the latest SVN version, but I
made all the same changes described in the previous email.  After making the
changes, I built LLVM, and then built the GCC front end.

I traced the "Cannot yet select" print statement to DAGISelEmitter.cpp, but
am unsure how to proceed.

Thanks again for your help,
Matt

Hi,

did you rebuild llvm-gcc after building llvm with your new intrinsic
defined?

Ciao,

Duncan.
