Bug #: 11642
Summary: -fvisibility-inlines-hidden should not hide explicit
instantiations
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: LLVM Codegen
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 7798

preprocessed testcase for a.cc
Clang with -fvisibility-inlines-hidden generates a hidden definition for
explicitly instantiated inlines.
Now think of the following scenario:
a.h defines class Foo.
a.cc has the instantiation for Foo<int>
b.cc uses Foo<int>
Now we build a shared library from a.cc, Foo::foo is not exported. When b.cc is
compiled it won't include a definition for Foo::foo and linking against the
shared library will cause a linker error.
