Tracking parts of expanded values in optimized debug
...d into two i32 loads), I would expect to see a new ISD::DBG_VALUE tracking each fragment of the input original debug variable. However, I can't see anywhere this is handled. There seems to be some support for this, through the DW_OP_LLVM_fragment DIExpression, and there is a function DIBuilder::createFragmentExpression which could be used to create an expression to track part of a variable, however these don't seem to be used much. Thanks, Ed
