cross configuration
===
../gcc/configure --target=arm-unknown-linux-gnueabihf --with-float=hard
--with-arch=armv7-a --with-tune=cortex-a15 --disable-multilib
--enable-languages=c,c++,fortran,java,lto,objc
compile command
===
./cc1 -O2 -fPIC bug.i -nostdinc
(if specify -fno-ipa-icf then the ICE will go away)
