It is produced during make check-gcc by the following command line: /home/jcmvbkbc/ws/tensilica/gcc/builds/gcc-13-1039-g2c2987950301-windowed-be/gcc/xgcc -B/home/jcmvbkbc/ws/tensilica/gcc/builds/gcc-13-1039-g2c2987950301-windowed-be/gcc/ -mtext-section-literals -mlongcalls -fdiagnostics- plain-output -O1 -w -c -o 20120727-1.o /home/jcmvbkbc/ws/tensilica/gcc/gcc/gcc/testsuite/gcc.c-torture/compile/20120727-1.c -- Thanks. -- Max
