[cfe-dev] Clang doesn't support Logical Operator supported in GCC Vector Extension?

[Yin Ma]

Hi,

 

Clang supports GCC Vector Extension.  However GCC Vector Extension supports

Logical operator like <, >  

 

If I try to compile the code like 

 typedef float float4 __attribute__((ext_vector_type(4)));

 

   float4 a;

   float4 b;

   float4 c;

   a = b > c;

  

the clang will 

   used type 'int  __attribute__((ext_vector_type(4)))' where arithmetic,
pointer, or vector type is required.

 

But if the code is 

  a = b * c;

 

Everything works. Do you know why vector logical operator is not supported
by this time? 

 

Thanks,

 

                                 Yin
