Bug #: 55391
Summary: [4.8 regression] ICE in adjust_address_1 at
emit-rtl.c:2180 breaks bulding cross to sparc64-linux
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mi...@it.uu.se
Attempting to build gcc-4.8-20121118 as a cross from x86_64-linux to
sparc64-linux fails with:

Found while checking to see if the native ICE reported in PR55388 could be
reproduced with a cross. Disabling libitm allows the build to complete. (I
also had to disable libsanitizer to work around a build error there.)
