[PATCH] D97129: [Support] unsafe pointer arithmetic in llvm_regcomp()

[Vitaly Buka via Phabricator via llvm-commits]

vitalybuka added a comment.

Can you please clang format according to premerge checks?



================
Comment at: llvm/lib/Support/regcomp.c:252
 #define	PEEK2()	(*(p->next+1))
-#define	MORE()	(p->next < p->end)
-#define	MORE2()	(p->next+1 < p->end)
+#define	MORE()	(p->end - p->next > 0)
+#define	MORE2()	(p->end - p->next > 1)
----------------
I understand all but this line. I guess it had no UB there.
