I have a project where allocateRegisters.toLiveness takes 220s out of a total build time of 240s. I'm not sure what exactly causes this...<br></blockquote><div><br>In case it's not obvious, this only happens with the x86/amd64 codegens. C and bytecode compile just fine. I'd try and solve it myself, but I haven't a clue where to even begin. That 240s total was on the fastest machine available to me; on my laptop it takes 20 minutes... What algorithm is toLiveness using? Does it have exponential complexity in the number of variables?<br>
