You may have noticed. There is zero test for -mtls-dialect=gnu2 on x86 in GCC and I only added one -mtls-dialect-gnu2 in glibc last year when I fixed GNU2 TLS bug in glibc: https://sourceware.org/bugzilla/show_bug.cgi?id=20309 So effectively, there is very little test for -mtls-dialect-gnu2 on x86. -- H.J.
