            Bug ID: 25654
           Summary: Clang compilation warning: C > UCHAR_MAX is always
                    false
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: idenx at yandex.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

lib/ProfileData/InstrProf.cpp:
if (C > UCHAR_MAX)
    C = UCHAR_MAX;
Here is compiler (gcc 4.9.2) warning during compilation of clang from trunk
that it's always false comparison. And it's true, because C declared as
uint8_t.
I can make a fix myself, if I understand it correctly.
