Function Documentation

◆ PerformReturnAdjustment()

static RValue PerformReturnAdjustment ( CodeGenFunction CGF,
QualType  ResultType,
RValue  RV,
const ThunkInfo Thunk 
)
static

◆ resolveTopLevelMetadata()

static void resolveTopLevelMetadata ( llvm::Function *  Fn,
llvm::ValueToValueMapTy &  VMap 
)
static

This function clones a function's DISubprogram node and enters it into a value map with the intent that the map can be utilized by the cloner to short-circuit Metadata node mapping.

Furthermore, the function resolves any DILocalVariable nodes referenced by dbg.value intrinsics so they can be properly mapped during cloning.
