[Tarantool-patches] [PATCH luajit v7] memprof: introduce cli flag to run dump parser

[Maxim Kokryashkin]

Hi, Igor!

Well, I see no obstacles with flag handling in Tarantool.
For instance, the -j flag proxy can do exactly what you want.

| review/tarantool/build  fckxorg/gh-5688-cli-for-memprof-parse ✔                                                                                                                                   239d16h
| ▶ ./src/tarantool -j on -e 'print(jit.status())'
| true	fold	cse	dce	fwd	dse	narrow	loop	abc	sink	fuse

| false	fold	cse	dce	fwd	dse	narrow	loop	abc	sink	fuse

Tarantool's flag handling is not pleasant to say the least,
but we should try to do the same as with -j.

Best regards,
Maxim Kokryashkin
