Some basic questions

[Mahdi Mohammadinasab]

I have some basic questions regarding libgccjit. I could not find the
answer in the documentation.

1. Does libgccjit do optimizations when generating the machine code?
2. Does it support other OSs like Windows?
3. If the output application depends on a static library (.a) I will
need to generate object file using libgccjit (call
gcc_jit_context_compile_to_file with GCC_JIT_OUTPUT_KIND_OBJECT_FILE
option) and use system linker to link it with the library. Is that the
correct approach?
4. Is there any planned feature missing from current codebase which
prevents it moving out of alpha stage?

Thanks,
Mahdi
