[LLVMdev] LowerFormalArguments: info on aggregates

[Konrad Anheim]

Hi,

All arguments processed in the function LowerFormalArguments seem to be 
are already lowered to machine types. In addition, the flag isByVal 
seems to be set for each argument passed on the stack, and cannot be 
used to indicate a struct/union.

Is there a way to tell if an argument is of a simple type or of an 
aggregate (within LowerFormalArguments)? Is there any better way 
processing stack alignment of incoming arguments? This information would 
be needed for correct stack alignment of structs vs. simple types in 
AArch64 big endian mode.

Thanks,
Conny
