--- Comment #11 from Peter Bergner <bergner at gcc dot gnu.org> --- Ok, I found the difference. The problem on the external gcc112 system (ie, the big-endian system) is that the system binutils doesn't support POWER8, so during gcc config/build, the power8 gcc support was disabled. I built/installed a new binutils and used that for my build and now my external build also ICEs. Vlad can you try using my build on gcc112? /home/bergner/gcc/build/gcc-fsf-mainline-r221324-2/gcc/xgcc -B/home/bergner/gcc/build/gcc-fsf-mainline-r221324-2/gcc -O1 -m64 -mcpu=power8 -mlra -S pr63491.i It uses /home/bergner/binutils/install/binutils-power8/bin/{as,ld}.
