A very nice benchmark. I have a question about this comment in the README:

The compilers vox dmd are, by a large margin, the fastest. 2 times faster than its closers competitor, tcc.

I don't see how this is true by looking at your table:

Lang-uage	Check Time [us/fn]	Compile Time [us/fn]	Build Time [us/fn]	Exec Path
Vox	1.5 (best)	N/A	5.2 (3.3x)	vox
Vox	2.0 (1.4x)	N/A	6.1 (3.9x)	vox
D	6.3 (4.2x)	13.4 (7.4x)	17.9 (11.4x)	dmd
C	1.8 (1.2x)	1.8 (best)	1.6 (best)	tcc

It seems to me that tcc is faster than dmd. It's also not clear what Check, Compile and Build time mean.

Is Check about just checking syntax? How is Build different than Compile?
