Just a few days ago I wrote about the Glibc math code seeing a 4x improvement on AMD Zen by changing the used FMA implementation. Merged overnight was a new generic FMA implementation for the GNU C Library and now yielding up to a 12.9x throughput improvement on AMD Zen 3...

I've tried my best to carefully follow Nick's instructions in binutils/README-how-to-make-a-release and feedback welcome. This is a point release over the previous 2.45 version, containing bug fixes and one new feature to help with a glibc bugfix: bfd will now mark binaries with GLIBC_ABI_GNU_TLS (i386), GLIBC_ABI_GNU2_TLS (x86-64, i386), and GLIBC_ABI_DT_X86_64_PLT (x86-64) where appropriate on GNU/Linux systems. The former two symbols have been backported to all applicable release branches for glibc. The latter was already there. Please make sure your branch is tracking the appropriate release branch for the version of glibc you ship - this is important in general, not just for this issue. This is needed to identify binaries built with a fixed glibc version for TLS. At configure-time, this can be disabled with --enable-gnu-tls-tag, --disable-gnu2-tls-tag, or --disable-mark-plt respectively. Note that the mark PLT configure option is not new, just we now use GLIBC_ABI_DT_X86_64_PLT as a tag instead of reusing GLIBC_2.36. Our thanks go out to all of the binutils contributors, past and present, for helping to make this release possible.
