Side table of dbg_value and dbg_label info for SelectionDAG ISel.
Synopsis
Declared in <llvm/CodeGen/SelectionDAG.h>
class SDDbgInfo;Description
We do not build SDNodes for these so as not to perturb the generated code; instead the info is kept off to the side in this structure. Each SDNode may have one or more associated dbg_value entries. This information is kept in DbgValMap. Byval parameters are handled separately because they don't use alloca's, which busts the normal mechanism. There is good reason for handling all parameters separately: they may not have code generated for them, they should always go at the beginning of the function regardless of other code motion, and debug info for them is potentially useful even if the parameter is unused. Right now only byval parameters are handled separately.
