8.1.1 Common gnu Attributes
These attributes are valid on all architectures.
- Tag_compatibility (32)
- The compatibility attribute takes an integer flag value and a vendor name. If
the flag value is 0, the file is compatible with other toolchains. If it is 1,
then the file is only compatible with the named toolchain. If it is greater
than 1, the file can only be processed by other toolchains under some private
arrangement indicated by the flag value and the vendor name.
