yaxunl added a comment. with the new pragma for associating types with extensions. This feature can be implemented by solely modify opencl-c.h by adding #pragma OPENCL EXTENSION cl_khr_fp64 : begin/end around vector double type definitions, e.g.
#pragma OPENCL EXTENSION cl_khr_fp64 : begin typedef double double2 __attribute__((ext_vector_type(2))); typedef double double3 __attribute__((ext_vector_type(3))); typedef double double4 __attribute__((ext_vector_type(4))); typedef double double8 __attribute__((ext_vector_type(8))); typedef double double16 __attribute__((ext_vector_type(16))); #pragma OPENCL EXTENSION cl_khr_fp64 : end #ifdef cl_khr_fp64 #if __OPENCL_C_VERSION__ < CL_VERSION_1_2 #pragma OPENCL EXTENSION cl_khr_fp64 : enable #endif #endif The #pragma OPENCL EXTENSION cl_khr_fp64 : enable is for suppressing diagnostics due to using double type in builtin functions. Ideally they should also be surrounded by #pragma OPENCL EXTENSION cl_khr_fp64 : begin/end. https://reviews.llvm.org/D27917 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
