iliya-diyachkov added inline comments.


================
Comment at: llvm/lib/Target/SPIRV/SPIRVCallLowering.cpp:392
       assert(Arg.Regs.size() == 1 && "Call arg has multiple VRegs");
+      if (!MRI->getRegClassOrNull(Arg.Regs[0]))
+        MRI->setRegClass(Arg.Regs[0], &SPIRV::IDRegClass);

18 LIT tests will fail if I remove this setRegClass(). On other hand, I found calls with register classes already set here in 27 LIT tests.
So I suppose it makes sense to leave this check and setting.
