The latest binutils has better debug support, so= I could imagine us ending up with some longer compiler times as a result -- t= here has to be more than just that here, though. Aside from that we have had a ton of vector codegen go in over the last few months, but this is a pretty huge increase so I agree it's worrisome. I'm adding Vineet to the CC list, as he's been doing some SPEC runs. I don't t= hink we've had any major runtime regressions, but looks like dwarf2out.cc times = have crept up a bit which is also worrisome. Also what exactly are you timing? Native boostraps on QEMU?=
