Some LLVM IR instructions were created according to those generated by LLVM from source.
I.e., load p, load a[1] based on p, load p again, store a[2] based on p, etc.
The machine code turned out to be slightly optmized, as shown on the

However, the machine code generated by JIT is not as good as that generated
by clang or llc.
Here is an example:
