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
