Sorry for my wrong post!

Hi Tom,
Thanks for your kind response!
> clang -include /path/to/libclc/headers/clc.h -I
/path/to/libclc/headers -Dcl_clang_storage_class_specifiers -target
amdgcn--amdhsa -mcpu=carrizo $INPUT_FILE -o $OUTPUT_FILE
When I tried to build cos.cl testcase
https://github.com/llvm-mirror/libclc/blob/master/test/cos.cl
$ clang -include clc/clc.h -Dcl_clang_storage_class_specifiers -target
amdgcn--amdhsa -mcpu=carrizo cos.cl -o cos.out
cos.cl:1:27: error: pointer arguments to kernel functions must reside
in '__global', '__constant' or
'__local' address space
__kernel void foo(float4 *f) {
^
1 error generated.
Then I added __local before float4 *f like this:
Index: cos.cl
===================================================================
--- cos.cl (revision 306265)
+++ cos.cl (working copy)
@@ -1,3 +1,3 @@
-__kernel void foo(float4 *f) {
+__kernel void foo(__local float4 *f) {
*f = cos(*f);
}
because [OpenCL] Improve address space diagnostics
https://reviews.llvm.org/D27671
then rebuilt again,
cos.cl:1:15: error: unsupported call to function _Z3cosDv4_f
__kernel void foo(__local float4 *f) {
^
1 error generated.
why not found *cos* function? please give me some hint, thanks a lot!
