Bug ID: 40719
Summary: Atomic qualifier not removed in lvalue conversion
Product: clang
Version: 8.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: al.gr...@arm.com
CC: blitzrak...@gmail.com, dgre...@apple.com,

Clang faults this C code:
error: returning '_Atomic(int)' from a function with incompatible result type
'int'
int f1(_Atomic(int) *p) { return *p = 1; }
int f2(_Atomic(int) *p) { return *p += 1; }
But the assignments undergo lvalue conversion which should remove
the _Atomic qualifier.
