FWIW the custom language is very close to C, and the examples are pretty much a 1-1 transposition.

I agree with you though on a different note. It's dubious to compare compilers by benchmarking them, because tests are highly arbitrary and are won/lost based on single weak links. It's not really an exact science, but rather something you can start with to figure out how things are behaving. I mostly base my opinions by looking at the assembly code each compiler generates, but a single bar graph is a better presentation for articles.

It could be fun to compare with Action!--it's been known to compile a reasonably good 6502 assembly (considerably better than other compiled languages for that platform), https://en.wikipedia.org/wiki/Action!_(programming_language),

It has been released as open-source together with the binaries, https://atariwiki.org/wiki/Wiki.jsp?page=Action

You should be able to run these using an Atari 8-bit (XL/XE model) emulator, like Atari800, https://github.com/atari800/atari800/releases or Altirra, https://www.virtualdub.org/altirra.html
