Freezing precompilation

[MilesCranmer]

On Julia 1.10 there are issues related to opening persistent I/O during precompilation.

I just installed julia-1.10-rc2 and now am seeing hanging precompilation on my entire base environment due to Random123 (which is an indirect dependency). Here is my system:

julia> versioninfo()
Julia Version 1.10.0-rc2
Commit dbb9c46795b (2023-12-03 15:25 UTC)
Build Info:
  Official https://julialang.org/ release
Platform Info:
  OS: macOS (arm64-apple-darwin22.4.0)
  CPU: 8 × Apple M1 Pro
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-15.0.7 (ORCJIT, apple-m1)
  Threads: 8 on 6 virtual cores
Environment:
  JULIA_FORMATTER_SO = /Users/mcranmer/julia_formatter.so
  JULIA_NUM_THREADS = auto
  JULIA_EDITOR = code

Related to #18 with @IanButterworth and @sunoru.

Is it potentially due to the following const which opens a process?

Random123.jl/src/Random123.jl

Lines 34 to 42 in 8341084

	cmd = Base.julia_cmd()
	push!(
	cmd.exec, "-e",
	"const __m128i = NTuple{2, VecElement{UInt64}};" *
	"@assert ccall(\"llvm.x86.aesni.aeskeygenassist\", " *
	"llvmcall, __m128i, (__m128i, UInt8), " *
	"__m128i((0x0123456789123450, 0x9876543210987654)), 0x1) ≡ " *
	"__m128i((0x857c266f7c266e85, 0x2346382146382023))"
	)

Hi, thanks for reporting this. I don't have an ARM Mac at hand to test but that is probably the cause. I will release a patch to skip these lines on those platforms for now. Please let me know if the problem is fixed after JuliaRegistries/General#97519 is merged.

Ideally, we should also implement those RNGs on ARM64 (#20), but I have been too busy recently to look into that.

That fixed it, thanks for the quick turnaround!!
