We recommend setting `dfa-jump-thread` to be enabled by default. It’s a
mature optimization that’s been supported since GCC 9.1.0. At the `-O2`
opt level, both the GCC and ICX compilers have this optimization enabled
by default.
Once it’s enabled, we saw a **13% performance improvement** in the
CoreMark benchmark on the X86 platform (Intel i9-11900K Rocket Lake),
and even a **15% increase** on the KunMingHu FPGA. Additionally, we
verified the correctness of this pass using SPEC 2017.
