llvm dev - Dec 2010 - [LLVMdev] Target instrinsics & metadata

Hi All,

Unless I missed something, it seems to me that metadata can not be carried by
target specific intrinsics when moving in and out of selectionDAG. The attached
patch add support for this.

The only point worth noticing is about the selectionDAGBuilder part : the
regular getValue() path is not used, as its intended --- and enforced --- usage
is for 'real' values, with a register associated to them.

This patch applies fine, breaks no regresion tests on top of tree and we are
using it here with our own backends.

Best regards,
