LLVM: lib/Target/DirectX/DXILRootSignature.cpp File Reference (original) (raw)

Go to the source code of this file.

◆ analyzeModule()

Root Signature are specified as following in the metadata:

!dx.rootsignatures = !{!2} ; list of function/root signature pairs !2 = !{ ptr @main, !3 } ; function, root signature !3 = !{ !4, !5, !6, !7 } ; list of root signature elements

So for each MDNode inside dx.rootsignatures NamedMDNode (the Root parameter of this function), the parsing process needs to loop through each of its operands and process the function, signature pair.
