Bug ID: 23529
Summary: Add support for gcc's attribute abi_tag (needed for
compatibility with gcc 5's libstdc++)
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
With the release of gcc 5.1, libstdc++ has started using the abi_tag attribute.
The attribute is documented here:
https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html
Its use in libstdc++ and effects on ABI compatibility between gcc and clang are
pointed out here:
https://gcc.gnu.org/ml/gcc-patches/2015-04/msg00153.html
It would be great if clang could support the abi_tag attribute and remain abi
compatible with gcc.
