Jeffrey A. Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P4 --- Comment #15 from Jeffrey A. Law <law at redhat dot com> --- OK. So the .original differences are due to new builtin decls which of course change the DECL_UIDs. That also twiddles memory allocation patterns which can have other downstream effects. So given -mno-lra is scheduled for removal in gcc-8, I'm downgrading to P4.
