Hello Joel, see libatomic_i.h in the GCC sources:
/* All sized operations are implemented in hidden functions prefixed with "libat_". These are either renamed or aliased to the expected prefix of "__atomic". Some amount of renaming is required to avoid hiding or conflicting with the builtins of the same name, but this additional use of hidden symbols (where appropriate) avoids unnecessary PLT entries on relevant targets. */ A proper fix would be to implement libatomic for SPARCv8.
