Bug ID: 27095
Summary: [ms] restrict qualifier on destructors and constructor
definitions are not allowed
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: andrey.kules...@intel.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
!- __restrict keyword is applied to the destructors and out-of-class
constructors is not allowed bu clang.
MSVC can compile both on a constructor/destuctor and gcc can compile 'restrict'
qualifier on a constructor. This can affect compatibility of Clang.
It seems that qualifier can be ignored with a warning -!
=======Environment=============
OS: Win
Language: C++
Version: trunk (3.9)
========How to reproduce=======
struct D { ~D() __restrict; };
D::~D() {}
class C{ C(); };
C::C() __restrict{;}
=============Error===============
>>>clang:
test.cpp(1,12) : error: 'restrict' qualifier is not allowed on a destructor
struct D { ~D() __restrict; };
test.cpp(2,5) : error: definition of implicitly declared destructor
D::~D() {}
test.cpp(5,4) : error: 'restrict' qualifier is not allowed on a constructor
C::C() __restrict{;}
>>>gcc:
<NO ERROR ON CONSTRUCTOR>
test.cpp:1:17: error: destructors may not be cv-qualified
struct D { ~D() __restrict; };
^
>>>MSVC: no diagnostics
