zixuan-wu added inline comments.


================
Comment at: clang/test/Sema/builtin-alloca-with-align.c:32
 void test8(void) {
+#if defined(__csky__)
   __builtin_alloca_with_align(sizeof(__INT64_TYPE__), __alignof__(__INT64_TYPE__)); // expected-warning {{second argument to __builtin_alloca_with_align is supposed to be in bits}}

Reusing the first warning is good.
