I want to `@code_native` a function, make some edits to the assembly and then run it.

For example a function I want to edit is

```julia
using SIMD

f(x, y) = any(x > y)

x = Vec{8, Float32}(1)
y = Vec{8, Float32}(0)

```

I would like some way to copy `@code_native debuginfo=:none f(x, y)` and then run it.

You can `llvmcall` and use assembly, but you’d need to edit it.  
Alternatively, if it’s big enough that those modifications are unwieldy, you could compile into a shared library with gcc and `ccall` it.

Here is an example: [VectorizationBase.jl/intrin\_funcs.jl at 2842337a85aefc5e3352e1b6272589f4e53c58ee · JuliaSIMD/VectorizationBase.jl · GitHub](https://github.com/JuliaSIMD/VectorizationBase.jl/blob/2842337a85aefc5e3352e1b6272589f4e53c58ee/src/llvm_intrin/intrin_funcs.jl#L934)
