[LLVMdev] LLVM Metadata from Pass to Backend optimization

[Konstantinos Parasyris]

Hello,

I am new in the LLVM infrastructure and I want to write a pass which 
creates extra information for each instruction. This information is 
going to be used by a back-end optimization. I am thinking
of using the Metadata structure to pass the data from the Analysis Pass 
to the Back end. Is this the correct methodology? Or should I use 
another mechanism?
