Hi Khaled, Check out X86TargetLowering::LowerReturn, and the call to getSRetReturnReg. The SRetReturnReg looks like a hack (each target that uses it, declares this variable individually), but that seems to be the current way of handling it. -K -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation

Hi, it seems like SelectionDAGBuilder expects returning of vectors (structures/arrays) to be lowered in either of the two ways: 1. Flatten the complex data types to simple data types, and return them using registers (done by TargetLowering::LowerCallTo) 2. sret demotion: return the address of the complex data type via a stack pointer Is there an option to do sret demotion via a register? if yes,

First, is the possible lack of conformance with the ABI you state, which I can't comment since I don't know that ABI very well. Second, is the fact that clang is not printing correct debug information (or is
