[LLVMdev] Reusing stacks slots for function arguments

[Max Kazakov]

Hi All,

Could someone suggest a way to make (the standard) spiller reuse stack slots
associated with function arguments? I was not able to convince it that argument
slots can be used as spill ones already keeping the value for certain virtual
registers thus getting a bit of useless moves between stack and registers.

Thanks in advance,

BR
