Bug ID: 49315
Summary: ICE when assigning a function to a pointer.
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: OpenCL
Assignee: unassignedclangb...@nondot.org
Reporter: anastasia.stul...@arm.com
CC: anastasia.stul...@arm.com, llvm-bugs@lists.llvm.org
When the extension for the function pointers is used
#pragma OPENCL EXTENSION __cl_clang_function_pointers : enable
void foo();
void bar(){
void (*f)() = foo;
}
frontend fails to compile it failing in the incorrect address space conversion
check.

This issue is not triggered in C++ for OpenCL mode that seems to follow
different conversion path.
