The original purpose was simply to collect programs which caused the compiler to fail. When he saw a bug report with a test case, he collected the test case, reduced it, and added it to the torture tests. The tests were simply run at various optimization levels. Tests which caused the compiler to crash were put in compile, tests which showed a miscompilation visible at run time were put in execute. I would guess that 920612-1.c, at least, could just be changed to use unsigned int, and it would continue to test whatever bug it was testing when it was originally added. Ian
