Hi,<br><br>I need to perform some transformation after code was lowered.<br>I think I need to do this in llc and use a MachinePass. However, it is unclear how.<br>I am able to change the register allocator:<br> llc -f -load XXX.so -regalloc=xxx foo.bc<br>but I don't know how to just insert a different pass and pass new command options to llc.<br>I found plenty of documentation about 'opt', but little about llc.<br><br>So, is this correct? Transformation after lowering should happen in llc?<br>How can I register and run a new pass (preferably as the last pass) in llc?<br>How can I see the hidden options of the tools?<br><br>Thank you,<br>Dan<br> <br /><hr />The New Busy is not the old busy.
