A brief look at the code points me the following snippet:

cluacov/src/cluacov/lj2/lj_arch.h

Lines 40 to 56 in 2a1178a

	#if defined(__i386) || defined(__i386__) || defined(_M_IX86)
	#define LUAJIT_TARGET LUAJIT_ARCH_X86
	#elif defined(__x86_64__) || defined(__x86_64) || defined(_M_X64) || defined(_M_AMD64)
	#define LUAJIT_TARGET LUAJIT_ARCH_X64

It seems the file is copied from LuaJIT sources and actual LuaJIT has the ARM64 branch:

https://github.com/LuaJIT/LuaJIT/blob/8ff09d9f5ad5b037926be2a50dc32b681c5e7597/src/lj_arch.h#L54-L70

Initially reported in tarantool/crud#211.

@hishamhm Is there a chance to get update here? Should I open a pull request?

[hishamhm]

Should be fixed in cluacov 0.1.3!

f485047 from PR #5 seems related. I can confirm that an installation from the scm-1 rockspec on an ARM64 machine is successful. Thank you!
