<html><body style="font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12px;">Hi all,<br /><br />I have two GIComplexOperandMatchers, one that takes [base(gpr)+offset(imm)], another that takes (global address inc offset) directly. It's quite possible that I'm not doing things the right way(tm) by having these, but they seem to be making the transition easier.<br /><br /><div>However, because these patterns are look identical to the parser, tablegen seems to give them both equal preference - yet in all instances, the direct memory addressing variant ought be preferred over the one that requires a pointer register. I'm 99% sure that <span style="float:none;background-color:rgb(255,255,255);color:rgb(0,0,0);font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:12px;font-style:normal;font-variant:normal;font-weight:400;letter-spacing:normal;text-align:left;text-decoration:none;text-indent:0px;text-transform:none;word-spacing:0px;">AddedComplexity is ignored by GlobalISel, and from </span>quick look through GlobalISelEmitter.cpp I cannot find any alternative. Preferably, such an alternative would be applied to Operands, at that (maybe asking a bit much).</div><div><br /></div><div>Before I go about renaming things such that alphabetical ordering gives me the results I want or hacking in a similar workaround, just want to check... is there a method I've missed for preferencing one pattern over another currently?</div><div><br /></div><div>Thanks,</div><div>Alex Davies</div></body></html>
