[clang] Fix crash in __builtin_strncmp and other related builtin functions 2023-08-25T20:54:50+00:00 Shafik Yaghmour shafik.yaghmour@intel.com 2023-08-25T20:49:27+00:00 33b6b674620d77e615d569f504b306aac528bab7 The implementation of __builtin_strncmp and other related builtins function use getExtValue() to evaluate the size argument. This can cause a crash when the value does not fit into an int64_t value, which is can be expected since the type of the argument is size_t. The fix is to switch to using getZExtValue().
