llvm dev - Aug 2008 - [LLVMdev] Custom lowering of Store !

How can I custom lower the ISD::STORE?
I am using -enable-legalize-types and trying to customize most of our
operations in xxxTargetLowering::ReplaceNodeResults(...)
There are hooks to get trunk-store and indexed-store customized,
But I can't get regular STORE customized...
Any suggestions?

Thanks

You have to modify SelectionDAGLegalize::LegalizeOp. Under case  
ISD::STORE: add code to handle custom lowering of store nodes.

Hi,

are you trying to custom lower ISD::STORE when it makes use of
illegal types, or always?  The Legalize*Types.cpp files are
only for when types are illegal, but then they do allow for
customization in a (fairly) systematic way.
