/* When compiled with -pedantic, this program will cause an ICE when the constant propagator tries to set the value of *str to UNDEFINED. This happens because *str is erroneously considered as a store alias. The aliasing code is then making *str an alias leader for its alias set and when the PHI node at the end of the while() is visited the first time, CCP will try to assign it a value of UNDEFINED, but the default value for *str is a constant. */ typedef __SIZE_TYPE__ size_t; size_t strlength (const char * const); char foo(); static const char * const str = "mingo"; bar() { size_t c; char *x; c = strlength (str); while (c < 10) { if (c > 5) *x = foo (); if (*x < 'a') break; } return *x == '3'; }
