I'm not too sure if these
cfg
s are the most optimised - feel free to request any adjustments!Currently
miri
doesn't have support for inline ASM, so any usage of thecmov
crate (on inline ASM-utilising architectures) causes a failure. I scouredmiri
's docs for a solution, but this also works.I have tested these changes locally - all architectures build, and
miri
works too!I'm unsure whether or not this should be included in the README, it wasn't here but it's no hassle either way.
