            Bug ID: 33447
           Summary: clang fix-it is incorrectly duplicating formatting
                    specifier in some conditions
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: joker.eph at gmail.com
                CC: llvm-bugs at lists.llvm.org

Test case:



void RawLog__(const char* format, ...)
   __attribute__((__format__ (__printf__, 1, 2)));

#define RAW_LOG_WARNING(...) RawLog__(__VA_ARGS__)

#define RAW_LOG(...) \
        RAW_LOG_WARNING(__VA_ARGS__); \
        RAW_LOG_WARNING(__VA_ARGS__); 

void foo(long long m) {
  RAW_LOG("%d", m);
}


Running: `clang test.cpp  -c -Xclang -fixit `

Change the call to the RAW_LOG macro to:

RAW_LOG("%lld%lld", m);
