Bug ID: 41070
Summary: Failure to compile CL code with address space
conversion
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: OpenCL
Assignee: unassignedclangb...@nondot.org
Reporter: anastasia.stul...@arm.com
CC: anastasia.stul...@arm.com, dr...@jwdt.org,

I am creating this bug on behalf of David although he is experiencing slightly
different behavior that we are discussing on this bug:
https://bugs.llvm.org/show_bug.cgi?id=40778
while working on his code I have encountered the following failure if OpenCL
code like this is compiled:
generic int* foo(private int* i){
return i;
}
Example command line to reproduce:
clang -cl-std=CL2.0 -x cl --target=amdgcn-amd-amdhsa a.cl
It fails with:
fatal error: error in backend: Attempting to emit FLAT_LOAD_DWORD_ci
instruction but the Feature_isCIOnly predicate(s) are not met
Not sure it is expected to work or not. So I am adding Matt and Sam that might
be able to shed some light on the problem. Feel free to reclassify the bug if
needed.
Thanks!
