...ointer you can then do: for (Function::const_arg_iterator I = F->arg_begin(), E = F->arg_end();I != E; ++I) { unsigned Bytes = TD->getTypeSizeInBits(I->getType()) / 8; // do stuff here } 2) The second case is when the dyn_cast above fails because the Callee SDValue is a ExternalSymbolSDNode. In this case you have to manually analyze the arguments using PartOffset. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I'm having trouble getting the function prototype of an ExternalSymbolSDNode inside TargetLowering::LowerCall(), this way i could get the original argument sizes before they're legalized into smaller parts. I need this sort of information because depending on the originaltypes of the arguments i need to use some regs or others. I tried using the isSplit flag in ArgFlags...

...implementing this for my backend. In LowerCall you can get the callee prototype info when the Callee SDValue is a GlobalAddressSDNode doing cast<Function>(G->getGlobal()) (where G is GlobalAddressSDNode *G = dyn_cast<GlobalAddressSDNode>(Callee)), but this won't work when it is a ExternalSymbolSDNode, for that case i had to add additional info into the ISD::OutputArg struct to know the real size of the splitted argument. -------------- next part -------------- An HTML attachment was scrubbed...
