cse1 (RTL) does some expression simplification on the fly such as
t = x 4
r = t 4
==
r = x 8
However for mmx shift operation, the mode (V1DI) for the const folding is
illegal -- resulting in ICE.

There is a general problem with vector shifts by scalar operands. The code
assumed that both operands are vector mode operands, so it tries to add both
constant shift operands using V1DImode.

I'm using both --with-build-sysroot and --with-sysroot when I compile GCC, so

You know if you compile cc1 manually inside the gcc directory, it will
compile with -O0 -g. Also you can use stage1-gcc directory to debug
