This could have been a story about any ISA but it warms my heart to see RISC-V optimizations like this appearing bit by bit every day.

RISC-V chips that are fast enough to get used are appearing now and, when they do, the software ecosystem is going to be ready to meet it.

In the past, the hardware usually came first with the software slow to appear after. This time, it is happening the other way around.

Thanks for the blog, I really enjoyed it. Good work. This just makes me appreciate and love compilers even more, they are a fascinating piece of software.

You can hook these benchmarks up to AI and it can automatically find and fix these regressions.

SVGs on Firefox are broken (like 0.1% of the size it needs to be).

This really shouldn't be free work.
