Bug ID: 90418
Summary: [10 Regression] powerpc-darwin9 bootstrap fails after
r271013
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
Target Milestone: ---
I've bisected to the rev. but of course, that might be exposing a latent.
this: (plus:SI (reg/f:SI 1 r1)
(reg:SI 0 r0)) [27 S16 A8])
looks somewhat suspicious....
