...nctions be passed in address registers instead of general-purpose registers. As LLVM internally converts all pointers to integers (in my case i32), there is no way for a backend to tell whether an i32 operand is really an integer or actually a pointer. Thus neither the instruction selection nor the CallingConvention stuff works for me as expected. It does not seem possible to solve this problem without modifying at least some of the original LLVM source code. So what would be the easiest (and least invasive) way to achieve this? I have thought about adding a new ValueType (say, "p32") and overriding...

...ved this issue by annotating EVT, although no more detail is given and the backend is not available TriCore backend was developed in 2009, before LLVM2.6. Is there support for this in newer LLVM versions? Is there any example on how this was solved or any one faced this problem later? Can I use the CallingConvention.td or the compatibility is impossible?

...something more clean, I was wondering how the community would accept a change in the TD, if the code at CallinvConvLower.cpp:138 would've passed the IsFixed flag to the AssignFn then all those workarounds wouldn't be needed, this example is only one of a few I can think of for expanding the CallingConvention tablegen capabilities regarding this issue. Thanks for the answer.

Hey, I am working on a new back-end, in my back end, I require to pass every argument through a register when calling a function, unless the argument is part of the ellipsis (...) and then pass it through the stack, I've tried creating a CCCustom function to analyze the operands when a function has var args, however, the information whether the out val is fixed or not is not passed into the
