Bug ID: 118890
Summary: usbsan failure for powerpc64le-unknown-linux-gnu
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---
I wanted to build a usbsan checking compiler on a big machine, and ran
../trunk/configure --prefix=$HOME --enable-languages=c,c++,fortran
--with-build-config=bootstrap-ubsan
on cfarm120.cfarm.net (powerpc64le-unknown-linux-gnu).
Boostrap resulted in numerous errors with
./../trunk/gcc/config/rs6000/rs6000.cc:10314:29: runtime error: left shift of
negative value -549755813823
../../trunk/gcc/config/rs6000/rs6000.cc:10315:29: runtime error: shift exponent
64 is too large for 64-bit type 'long int'
