With my Rust programmer hat on: I recommend that you don't do that. Instead, have your Rust code call Gecko's C/C++ CPUID code. Or set some global variable with the "has SSE2" flag in your C++ code before the Rust code gets invoked, and have the Rust code test the SSE2 flag. It's not worth using unstable features, especially `asm!` which is fundamentally flawed and shouldn't be stabilized, just to do something this simple. With my Esteemed Mozilla Alumni hat on: It's absolutely ridiculous that Mozilla lets Debian and Red Hat choose what tools Mozilla uses to build its software. Mozilla needs to use the best tools for the job, and assist (mildly) in helping Debian and Red Hat cope with whatever difficulties they incur due to that. Not just Rust, but GCC/Clang and NSS and everything else. And, same with ESR; even reading this sentence cost you more effort than ESR is worth.
