… skip list When building with --with-lto, --enable-bolt and --enable-shared, GCC creates optimized function clones with the suffix .lto_priv.0. The sre_ucs*_match functions use computed gotos, which BOLT cannot optimize, so their .lto_priv.0 clones must be skipped as well. Static builds and Clang's LTO implementation are not affected.
