File that causes the ICE, preprocessed

Hello,

thank you all for g++!

I get an ICE while trying to cross-compile the attached file with -O2:

$ /usr/bin/arm-linux-gnueabihf-g++    -O2   -c gcc-ice.cc -o /tmp/gcc-ice.o
during RTL pass: expand
gcc-ice.cc: In function ‘void baseline::exec_ops(const Op*, const void**, const
char*, char*, int)’:
gcc-ice.cc:5142:13: internal compiler error: in convert_move, at expr.c:218
 static void exec_ops(const Op* ops, const void** args,
             ^~~~~~~~
0x7ff9d453c09a __libc_start_main
        ../csu/libc-start.c:308
Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-8/README.Bugs> for instructions.

$ /usr/bin/arm-linux-gnueabihf-g++ --version
arm-linux-gnueabihf-g++ (Debian 8.3.0-2) 8.3.0


The source compiles fine with g++ 9.2.1.

Enrico
