Bug #: 14974
Summary: clang is too aggressive in applying #pragma weak
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Given
#pragma weak foo
struct S { void foo(); };
void S::foo() {}
#pragma weak zed
namespace bar { void zed() {} }
#pragma weak bah
void bah() {}
#pragma weak baz
extern "C" void baz() {}
Clang produces a weak symbol in all cases. Gcc produces it only for baz, so it
looks like we can restrict the pragma just to extern C decls.
