Subject: [PATCH] GCC: fix mixing __attribute__ with C++ attributes
|
|
|
|
GCC does not support mixing __attribute__ with [[...]] attributes.
|
|
On the other hand [[clang::lto_visibility_public]] isn't supported
|
|
by GCC and only emits a warning. Therefore define Clang specific
|
|
attribute and leave it empty for GCC.
