Subject: [Bug bootstrap/48679] New: [4.7 regression] bootstrap comparison failures on m68k-linux
Date: Tue, 19 Apr 2011 07:42:00 -0000 [thread overview]
Message-ID: <bug-48679-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48679
Summary: [4.7 regression] bootstrap comparison failures on
m68k-linux
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mikpe@it.uu.se
The last 4.7 snapshot I was able to build on m68k-linux was 4.7-20110326.
Since then, every single weekly snapshot has failed with bootstrap comparison
failures. Some weeks other archs have also seen bootstrap comparison failures
but recently they aren't, however m68k-linux still does:

I will attempt to bisect this, but with the multiple generic bootstrap
comparison failures 4.7 has experienced recently, it's going to take some time.
