Hi, @svenvh : I attached test.cl.txt here which is the dumped opencl source
file. Unfortunately I do not know exactly how to reproduce the infinite loop
offline with this source. I extracted out the following simplified kernel which
can reproduce the hang with
clang -c -Xclang -emit-llvm -O0 test.clcpp
__kernel void nonceGrind(__global ulong *headerIn, __global ulong *nonceOut) {
ulong m[16] = { headerIn[0], headerIn[1],
headerIn[2], headerIn[3],
0, headerIn[5],
headerIn[6], headerIn[7],
headerIn[8], headerIn[9], 0, 0, 0, 0, 0, 0 };
*nonceOut = m[4];
}
However, I am afraid it may not fully represent the original issue. This is
because after I break out the loop in
ASTContext::removeAddrSpaceQualType, I am seeing the following assert:
clang: /home/chfang/llvm-project/clang/include/clang/AST/Type.h:677: void
clang::Qualifiers::addConsistentQualifiers(Qualifiers): Assertion
`getAddressSpace() == qs.getAddressSpace() || !hasAddressSpace() ||
!qs.hasAddressSpace()' failed.
Hopefully the information is useful, and you are able to help. Thanks.
