Well,then I am not quite sure about the usage of this testsuite.Most
testsuites seem to be used to test whether or not a kind of
optimization works,and according to your view,this testsuite seems to
be useless.
So do you think it is proper if we remove this testsuite from the
GCC testsuites?

Hi all,
I am facing with a GCSE problem on this GCC
testsuite(gcc/testsuite/gcc.c-torture/execute/pr38819.c),using
GCC-4.4.0:
extern void exit (int);
extern void abort (void);
volatile int a = 1;
volatile int b = 0;
volatile int x = 2;
volatile signed int
