Hi,<br>
<br>
We are currently developing an LLVM target for a micro-controller,<br>
and would like our TargetLowering::LowerCall method to emit<br>
PUSH instructions (instead of STORE) to pass arguments (which<br>
would improve code density for function calls).<br>
<br>
Is there a way of keeping track of the stack pointer changes<br>
implied by the PUSH instruction to calculate the correct<br>
offsets in RegisterInfo::<u></u>eliminateFrameIndex when the call<br>
sequence is generated ?<br>
<br>
Thanks a lot in advance,<br>
Rod<br>
