...n think of is a custom CCState which gets told about each argument as it passes by and allows CCCustom functions to access its special information (or, possibly, a CCIf with a cast). CCCustom<"TellCCStateAboutArg">, [...] CCIf<"cast<MyCCState>(State).isPointerArg()">, CCAssignToReg<[P1, P2]>>, Putting that information in the InputArg/OutputArg and incorporating it the CCAssignFn interface allows a more straightforward implementation in the targets, in my view (for both our uses). It's also information that's readily available w...

Hi, (Forward from cfe-commits, where some backend stuff has come up). This is an issue I've been thinking about quite a bit recently, and I agree that the biggest problem is the one below: > * The big thing still missing here is that there is no logic to check how many VFP registers have already been used for other arguments. When deciding whether to pass an argument as a homogeneous
