DPCT1077

Message

<macro name> redefines a standard SYCL type, which may cause conflicts.

Detailed Help

SYCLomatic detected that the code redefines a standard SYCL* type, which may cause conflicts in the included SYCL header files.

Suggestions to Fix

Rename the macro to avoid conflicts with standard SYCL types.

For example, this original CUDA* code:

// test.h
inline void bar(cudaDeviceAttr attr) {
  ...
}

// test.cu
#define int2 int32_t
#include "test.h"

void foo() {
  int2 a;
  ...
}

results in the following migrated SYCL code:

// test.h
#include <sycl/sycl.hpp>
#include <dpct/dpct.hpp>

inline void bar(int attr) {
  ...
}

// test.dp.cpp
/*
DPCT1077:0: 'int2' redefines a standard SYCL type, which may cause conflicts.
*/
#define int2 int32_t
#include "test.h"

void foo() {
  int2 a;
  ...
}

which is rewritten to:

// test.h
#include <sycl/sycl.hpp>
#include <dpct/dpct.hpp>

inline void bar(int attr) {
  ...
}

// test.dp.cpp
#include "test.h"

void foo() {
  int32_t a;
  ...
}
