Bug ID: 26117
Summary: msvc-cl and clang-cl disagree on what can be
static_asserted
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: jmuizel...@mozilla.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
The following program compiles with msvc-cl but does not with clang-cl.
The Offsetof macro is the one from msvc's stddef.h
#include <stdint.h>
#define Offsetof(s,m) (size_t)( (ptrdiff_t)&reinterpret_cast<const volatile
char&>((((s *)0)->m)) )
struct MyClass {
int myMem;
};
static_assert(Offsetof(MyClass, myMem) == 0, "boom");
You can run into this when pre-processing source from msvc to compile with
clang-cl.
