[cfe-dev] More cases not supported RE: Clang doesn't support Logical Operator supported in GCC Vector Extension?

[Yin Ma]

Hi,

typedef float  float4 __attribute__((ext_vector_type(4)));
typedef long   long4 __attribute__((ext_vector_type(4)));
typedef int    int4 __attribute__((ext_vector_type(4)));


int main()
{
  float4 af, bf;
  long4  al, bl;
  int4 ret;
  
  ret = (bf != af);
  ret = (bl != al);     
  
  return 0;
};

k.c:13:7: error: assigning to 'int4' from incompatible type 'long4';
  ret = (bl != al);
      ^ ~~~~~~~~~~

Clang is not supporting the GCC Vector Extension in this case. 
Does anybody know if there is a plan to fix this?

Thanks,

                            Yin

Ah, hmm... looks like we only support vector select in OpenCL mode at
the moment.
